12 mm lens for small pixels
Low distortion
Excellent corner brightness
The Kowa LM12JCM lens was designed for monochrome cameras having 6 micron or larger pixels, and color cameras having about 8 micron or larger pixels. This lens has 100 lp/mm resolution at center and 80 lp/mm in corners.
This lens has a compact metal housing that moves the front and rear spherical elements independently for better resolution and contrast, regardless of working distance. The focus and aperture adjustments lock-down with thumb-screws to resist equipment vibration.
