The JC Series is the go-to lens for many machine vision projects. It has all the features and performance characteristics most applications demand.
This Kowa LM75JC 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.
