Through their special optical design, the anti-shading lenses have very flat image sided chief ray angles. This enables the lens to image on sensors with micro lenses where large angles work very destructive on the imaging performance of the lens/camera system.
Schneider 1.3" lenses
Lenses for large image circles with an anti-shading lens design
These lenses are made for large sensors with up to a 24 mm sensor diagonal. Whilst the Xenoplan 28/2,0 and Xenoplan 35/2,0 are regular 1.3" lenses with relatively short working distances, the other 4 lenses in this series come with a special optical design to prevent shading on sensors where micro lenses are located in front of the pixels. This of course works in favour of the resolution as well, resolving a pixel size of up to 2.5 µm.
Reasons to use the Schneider Kreuznach 1.3" lenses and Anti-Shading lenses
Despite the large image circle, these lenses come with relatively short focal lengths and working distances, which make large field of views possible whilst keeping the space requirements tight.
Just like most other Schneider C-mount lenses, these ones are coated from 400 nm to 1000 nm.
- Sensor size: 1.3"
- Lens mount: C-mount
- Minimum pixel size: 3.5 µm (regular) and 2.5 µm (anti-shading)
- Miscellaneous: Anti-Shading
