The JC Series is the go-to lens for many machine vision projects. The Kowa LM16JC has all the features and performance characteristics most applications demand.
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.
The optical resolution is 100 lp/mm at center and 60 lp/mm at the corners. The minimum object distance is just 20 centimeters.
The 16 mm focal length is ideal for many projects. Image distortion is minimal – just .8% for a 1/2 size sensor – making it good for pattern match and OCV applications. And a system having a 16 mm lens will be more compact than one having a 25 or 35 mm lens.
