Zeiss Dimension 25mm f2 C-Mount Industrial lens

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

Exceptional Image Quality

Thanks to ZEISS Dimension lenses’ outstanding image quality, even the smallest structures are clearly resolved. This reduces the demands placed on downstream image processing and makes shorter production times possible. In addition, the lenses’ extremely high image resolution is what makes certain measurements and the ability to collect some data possible at all.

Correct Flange Focal Distance Tolerances

Precision is crucial in industrial applications. For maximum image sharpness, the lens and camera must work perfectly together. The smallest deviations in the flange focal distance can have negative effects on imaging performance. This is why the ZEISS Dimension lens family is equipped with the innovative adjustment mechanism. The benefit of this system is that it allows the back focus distance to be corrected by up to +/- 0.2 millimeters without having to disassemble parts of the lens.

ZEISS T* Coating for High-Contrast Images Without Reflections

The ZEISS Dimension lenses feature all ZEISS T* coating. The careful selection of the layers deposited on the lenses ensures both the high and uniform transmission of light from the visible spectral range to the near-infrared wavelength range.

For Sensors Up To The 4/3” Format

ZEISS Dimension lenses can be used with all common sensor formats that are offered in combination with the C-mount. The range of compatible formats extends up to 4/3” sensors. All ZEISS Dimension lenses make it possible to fully exploit the resolving power of sensors with a pixel size of up to two microns. They stand out due to their high speed with a maximum aperture of f/2, or f/2.8 at 8 mm. This not only brings advantages in low light – the lenses’ high speed makes short exposure times possible, resulting in faster processes.

Scales can be Read From Any Position

The mounting position of lenses on cameras in industrial applications can vary greatly. This often leads to scales being in inconvenient positions that are difficult to see during operation. To ensure optimum legibility at all times, the azimuth alignment of the scales can be corrected. Doing so is as easy as loosening three screws, moving the scales into the desired position and retightening the screws.

Locking Screws for Aperture and Focus

To ensure maximum image quality, eliminating interference from external vibrations is extremely important. This is why ZEISS Dimension lenses are equipped with three locking screws each on the aperture and focus ring. They prevent the lens settings from shifting unintentionally as a result of vibrations. All ZEISS Dimension lenses have been extensively tested for reliable performance under permanent mechanical stress and meet the stringent requirements of DIN ISO 9022.
