CA-L series
CA-LHE Series
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.
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.
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.
