It is a repetitive type job not really made for tall people with all the low shelving they have. Cons Not enough pay. What are people saying about the leadership at Carl Zeiss Vision?

Management, some have neen questionable buy majority of management are very well versed in their positions and fair to their employees. Pros consistent work day.

Eyeglasses, telescopes, microscopes, drawing instruments, thermometers, barometers, balances, glassblowing accessories and other apparatuses purchased from foreign suppliers were also sold in a small shop.

In he began to make simple microscopes which almost immediately met with especially good commercial success.

Zeiss microscopes could be focused by moving the column that carried the optics, instead of the object stage. Business was so good that he was able to hire an assistant and move to a larger workshop by early A total of 27 simple microscopes were delivered to customers beyond the borders of the grand duchy in Three difficult years followed with poor harvests, business crisis and revolution in the grand duchy, but by , Zeiss and his microscopes had established a good enough reputation to receive an attractive offer from the University of Greifswald in Prussia.

Nothing came of the offer, and Zeiss was to remain in Jena for better or worse, when an influential mathematician maintained that such a position should not be filled by a "foreigner.

She died giving birth to his first son in February of the following year. Roderich survived to eventually join his father in the family firm.

They would have one son, Karl Otto and two daughters, Hedwig and Sidonie Zeiss ran his workshop in a strict paternalistic fashion. Microscopes produced by the apprentices which did not meet the strict standards of precision he set were destroyed on the workshop anvil personally by Zeiss.

The working hours of the shop were 6 AM until 7 PM. Despite these strict rules, the working environment in the shop was very good. New recruits to the workshop were interviewed extensively in his home over a glass of wine.

As the firm expanded, by the Zeiss health clinic was established which guaranteed employees free treatment by a clinic doctor and free access to medication.

If a worker was unable to work wages were paid for six weeks with a further six weeks at half wages. Worker morale at the Zeiss works was consistently good.

Production of microscopes in was a handcraft and art more than manufacturing enterprise. Each worker produced an instrument from start to finish without any division of labor.

Only such assemblies which were particularly time consuming, such as the stage, were prepared in series in advance.

Matthias Jacob Schleiden had been an interested patron and advisor since the founding of the firm, frequently spending hours at the workshops.

He advised Zeiss to concentrate his efforts on the microscope which was critical for the rapidly advancing science of cellular anatomy and very much in demand.

Schleiden had a personal interest as this was his field of study. As a result of the interaction, the first microscopes products of the workshop, the simple microscopes, were constantly improved.

They were very favorably reviewed by the influential microscopist and botanist Leopold Dippel The optics for the simple microscope included a triplet of fold magnification, for 5 Talers, and one of fold magnification, for 8 Taler.

These pushed the limits of the simple microscope. Greater magnification would require compound microscopes. Zeiss would need to expand his offerings if he was not to be made irrelevant by his competitors.

Production of compound microscopes required extensive research, which he had foreseen long in advance. Zeiss had developed into something of a bookworm in his limited spare time, researching everything available on theory of the microscope.

He wanted, above all, to move past the prevailing methods of microscope production which relied on empirical matching of sets of lenses which would make up the high magnification compound lenses he needed for compound microscope optics.

Empirical methods used a selection of lenses, exchanging and examining elements, altering lens spacings again and again until a usable lens was obtained.

Many dozens of lenses could be examined to produce the combination of three elements used in a microscope lens. A reasonably good lens obtained this way was altered and tried again and again to find the best result.

To some extent, these designs could be reproduced, but each item was an empirical fit of the small elements which could not be reproduced exactly with the work methods used.

Zeiss was from the beginning more a fine machinist than an optician. This meant that he was less constrained by the traditional work methods and thinking of contemporary opticians and more open to innovation.

He decided to pursue the design of microscope optics by theoretical calculation, which expert opinion considered impossible for various reasons. Zeiss had already attempted to acquire the required theory in his evening literature studies.

These are described as "Small body tube, consisting of a field lens and two oculars with an adaptor to attach the tube to the stand and doublet objectives of stands 1 through 5 to allow use of the doublets as objectives to obtain two stronger magnifications after the fashion of the compound microscope.

The power doublet of the simple microscope yields in this fashion and fold magnification. By the publication of the 7th, , price list in August , newly developed compound microscopes appear in 5 different versions.

The largest of these, costing 55 Taler, was a horseshoe foot stand as made popular by the well known Parisian microscope maker Georg Oberhaeuser. Under the object stage Zeiss introduced a domed aperture plate and a mirror mounted to allow not only side to side, but also forward movement to produce oblique illumination.

Each microscope suite was produced to order for his customers so that they could choose their preferred optical components; objectives, oculars and illumination.

The objectives for these new compound microscopes were still empirically design but nonetheless met with immediate approval from Leopold Dippel.

The D objective was compared very favorably with the similar power objectives of Belthle and Hartnack successor to Oberhaeuser.

The F objective is even described as the equal of much more expensive objectives from established makers. That was, of course the problem.

When selling to researchers at the forefront of their fields, "almost as good" is a commercial disaster. Zeiss knew quite well that his strongest objectives could not match the quality of the Hartnack water immersion objectives.

Every attempt to empirically design a satisfactory water immersion objective had failed. To solve his problem Zeiss returned to his original plans to design his objectives based on a calculated theoretical basis.

He renewed his search for a collaborator and this time chose Ernst Abbe , a private docent, or associate professor, at the university.

A first step in the rational production of optics was a modernization of the workshop methods. The plan was to measure every individual property of each lens element before an objective was constructed to allow precise reproduction of the optical system.

The D objective, for example contained 5 lenses. Each was composed of glass with a specific index of refraction, with exact curvatures, of a specific focal length and exact spacings.

Fraunhofer had arrived at the same solution long before but the procedure had remained a trade secret of his workshop.

Every attempt to empirically design a satisfactory water immersion objective had failed. To solve his problem Zeiss returned to his original plans to design his objectives based on a calculated theoretical basis.

A first step in the rational production of optics was a modernization of the workshop methods. The plan was to measure every individual property of each lens element before an objective was constructed to allow precise reproduction of the optical system.

The D objective, for example contained 5 lenses. Each was composed of glass with a specific index of refraction, with exact curvatures, of a specific focal length and exact spacings.

Fraunhofer had arrived at the same solution long before but the procedure had remained a trade secret of his workshop.

Abbe constructed a series of new measuring apparatus to measure focal lengths and refractive indices. The result of all of this effort was clear by Outwardly the microscopes had hardly changed, but due to the rationalization of the work flow more microscopes were produced with the same personnel.

Abbe could now proceed with the actual task, namely calculation of the theoretical objective designs. Despite this, there were many obstacles to overcome.

It was before the work was complete. Abbe had recalculated the existing A through F objectives for systematic production and added four new, larger aperture, objectives AA through DD in this series.

Most important, he added three water immersion objectives which resolution and image quality equalling anything available from Hartnack, Gundlach or other competitors.

In catalog number 19, Microscopes and Microscopical Accessories, it was announced that, "The microscope systems presented here are all constructed on the basis on the recent theoretical calculations of Professor Ernst Abbe of Jena.

This was also reflected in the prices. While the best microscope cost Taler in , in one paid Taler for the top of the line.

Despite this, business remained brisk and the new objective system garnered high praise at a conference of natural scientists and physicians in Leipzig.

Zeiss repaid Abbe for his endeavor with a generous profit sharing arrangement in the workshops and made him a partner in As one condition of his financial participation Abbe was obligated not to expand his responsibilities at the university further.

On 14 October the completion of the th microscope was celebrated and the staff had grown to 60 employees in the meantime.

In addition Roderich made important contributions in the design of microphotographic apparatus. Carl Zeiss remained active in the firm on a daily basis.

In recognition of his contributions Carl was awarded an honorary doctorate by the faculty of the university of Jena in at the recommendation of one of long term collaborators, The zoologist Prof.

A move to modernization and enlargement of the firm was encouraged by Ernst Abbe, while Zeiss remained somewhat more conservative based on the many setbacks he had experienced.

Nonetheless, by the 80s the transition to large scale operations was underway. By the firm was enjoying solid business success.

The firm published its catalog No 26 as an illustrated and bound volume of 80 pages in an edition of copies. The always thrifty Zeiss required the retailers to share the cost of three or four silver groschen per copy.

The firm was even opening field offices in and outside the country. After mastering the problem of producing objectives based on theoretical calculation one problem remained, namely the production of suitable optical glass.

At the time optical glass was obtained from England, France or Switzerland and left much to be desired in quality, reliable availability, selection of optical properties and prompt delivery.

The optical properties were not consistent from batch to batch and, as important, those glasses which could be obtained were not ideal for the properties calculated to give the best correction in a microscope objective.

Abbe and Zeiss were convinced that the optical qualities of the microscope objective could be improved further if glasses with certain properties could be obtained.

Unfortunately, no such glasses existed. Zeiss once again supported Abbe in his theoretical work with the resources of the workshop to produce objectives using liquids in lens triplets to test his theory by , known as polyop objectives in the workshop.

Liquid lens triplets were not a new idea. They allow access to several optical properties which are not accessible in glasses.

Unfortunately, they are not commercially viable. Superior optical corrections were possible. For the first time, these objectives were better than anything made anywhere.

This result provided the argument for developing new glasses. Abbe discussed the problem of expanding the range of properties of optical glasses with the major producers no success but he continued to search for a way forward.

Zeiss and Abbe responded very enthusiastically to the enquiries of the chemist and glass technician Otto Schott when Schott contacted Abbe to seek help characterizing new chemical compositions in glasses.

Schott was uniquely skilled at producing small batches of experimental glass compositions in high quality. He was convinced to move to Jena and expand his experiments.

After demonstrating dozens of successful experiments, Zeiss used his credibility and connections to obtain financial support from the Prussian government for the efforts.

Within two years of the establishment of a glassworks in Jena, Zeiss, Abbe and Schott could offer dozens of well characterized optical glasses with repeatable composition and on large scale.

The firm still operates as Schott AG. The apochromatic objectives represented the success of collaborations lasting almost two decades.

In December Zeiss suffered a mild stroke, from which he fully recovered. The grand duke enrolled him in the Order of the White Falcon for his 70th birthday in , the same year the apochromatic objectives appeared on the market.

These represented the final realization of the grand design for the theoretical design of objectives inspired by and made possible by Zeiss and realized by Abbe; they delivered previously unknown image quality.

The members of the congress of Russian physicians were so inspired by the new objectives that they made Zeiss an honorary member. Zeiss was able to attend the celebration on the occasion of the completion of the 10,th microscope on 24 September , to which all employees and their spouses were invited.

It was a lavish party remembered in Jena for decades. Zeiss suffered a rapid decline and, after several strokes in the last quarter of , died on 3 December Zeiss is buried in Jena.

In final analysis of the contributions of Carl Zeiss one must conclude that, although he introduced several improvements in the mechanics of the microscope, he did not personally introduce groundbreaking innovations.

His critical contributions were his insistence on the greatest precision in his own work and in the products of his employees and that he maintained from the beginning close contacts to the scientists who gave him valuable insights for the design of his microscopes.

The greatest contribution of Zeiss was in his steadfast pursuit of his idea to produce microscope objectives based on theory, even when his own efforts and those of Barfuss failed.
