Lenses (for Machine Vision)

CA-L series

Ultra High Resolution, Low Distortion Lens Supporting 4/3" Images

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 centre of the lens, which enables the capturing of images with higher contrast. These lenses bring out the full capabilities of 4/3" and 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 (CA-LHE12 and CA-LHE16), they reduce aberrations over a wide range all the way to nearly infinite far shooting.

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.
