The ZEISS Classis lens family offers extraordinary image quality with high contrast for technical and industrial applications in addition to a precise fixture for focus and aperture. The outer design is characterized by a full-metal housing as well as a focus ring, which allows precise manual focusing.

The lenses cover linescan sensors up to 43 mm (4k to 8k) or full frame area sensors with 24 x 36 mm (up to 42 Mpixel). They are available with F-Mount and M42x1-Mount (45,5 mm Flange Focal Distance) for more stability. The lens family consists of five lenses from 25 mm to 85 mm. This range is completed by the lenses of the ZEISS Interlock family.

ZEISS lenses for technical applications are key components in complex production processes (Machine Vision) as well as in optical metrology, medical applications, traffic enforcement, quality assurance, sports and many other applications. Here they prove their outstanding image performance and reliability. Due to the precise manual adjustment of the helical focusing mount you will gain much better results than with comparable lenses.

Stress Test

ZEISS lenses need to operate perfectly in extreme conditions, withstanding everything from scorching heat and bitter cold to sandstorms and severe vibrations. The video shows how ZEISS researchers systematically submit lenses to extreme stresses in order to arrive at findings that can help in future lens design and development. The video explains how a lens with fixing screws was tested regarding following norms:

  • DIN ISO 9022
  • DIN EN 60068-1: 1988-06
  • DIN EN 60068-2 Part 64: 2009-04
  • MIL-Std 810G

High-quality metal housing

Noticeable quality and high value stability qualify ZEISS lenses for decades of intense use. The high-quality craftsmanship of the all-metal mount, the metal housing and the aperture ring as well as the robust front bayonet ensure reliable results.

Fixing srews for focus and aperture

ZEISS Classic lenses are equipped with small screws to fix focus and aperture to get stable and reliable measuring results even in rough industrial conditions. Both the locking screws and the stable design make the lens inured to vibrations, improve measuring repeatability and avoid machine downtime.

ZEISS T* anti-reflective coating

The optical elements of ZEISS lenses feature T* anti-reflective coating on all surfaces and an optical design that guarantees images of superior brilliance at all times, even in unfavourable lighting conditions. The first coating techniques were employed by ZEISS as long ago as in the 1930s.

High Speed Lenses

Good optical quality captured in low light always begin with a fast lens for a system or a camera. Because, a fast, high-performance lens captures as much light as possible. And a lens with a large maximum aperture leads to the best results when shooting in unfavourable light.
