Description
With focal length 4 mm, aperture F2.0 - F16, image circle Ø8 mm (1/2"), OPT-C0420-2M belongs to the series “2 MP Fixed Focal Length Lenses” by OPT Machine Vision. Also: working distance 100 mm - ∞, C-Mount.
The 2 MP series is OPT's entry level among the fixed focal length lenses: compact C-Mount lenses with lockable focus and aperture rings, designed for cameras with pixels from 5.5 µm and sensors up to 2/3". The illumination is uniform, and vignetting stays low. They are used where a robust standard lens is enough: presence checks, position detection, simple code reading and monitoring of assembly stations.
When choosing a lens, what counts is the interplay of sensor size, pixel size, field of view and working distance - the focal length alone says little. If you tell us your camera and inspection task, we check the combination and, if needed, suggest suitable lighting to go with it. The dimensional drawing and the STEP model are included.
