Lenses (for Machine Vision)

CA-L series

Ultra High-Resolution, Low-Distortion Lens Supporting 4/3" Image Sensors

CA-LHE Series

High-resolution design

Even though these lenses support full-size C-mounts, they guarantee a resolution of 160 cycles/mm at the center of the lens, which enables the capturing of images with higher contrast. These lenses bring out the full capabilities of 4/3", 21 megapixel cameras.

4/3" image dedicated design

Even though these lenses support 4/3" images, they attain a TV distortion of 0.02% (CA-LHE16). What’s more, even though they have a minimum WD of 0.1 m 0.3' (CA-LHE12 and CA-LHE16), they reduce aberrations over a wide range all the way to nearly infinite far image capture.

Wide-band multi-coating

Using wide-band multi-coating reduces the occurrences of ghosting and flares while also enabling highly-efficient transmission over a wide wavelength band from visible light to near-infrared.
