USED CONDITION. This item has been used, potentially in an industrial setting. It may have dust, grime, and scratches present. Although we expect this item to generally be in working condition, we have not tested it to verify full operational characteristics.
We have several Kowa LM12JC lenses that were previously used in a factory environment. They are dusty, have small scratches on the metal housing, and may be missing a locking thumb screw. No dust was observed inside the lens assembly.
The JC Series is the go-to lens for many machine vision projects. This Kowa LM12JC 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 10 centimeters.
