Description
OPT-S0856, an M12 fixed focal length lens of the series “M12 Fixed Focal Length Lenses” by OPT, comes with focal length 8 mm, aperture F5.6, image circle Ø9.3 mm (1/1.7"). Further key data: working distance 80 mm - ∞, S-Mount (M12).
The M12 series brings OPT optics to the S-Mount format: short overall length, fixed aperture F5.6 with large depth of field and a resolution close to the diffraction limit for sensors up to 1/1.7". The chief ray angle stays below 7.45°, so the illumination remains uniform. It sits in board-level cameras, smart cameras and code readers where a C-Mount lens would not fit.
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 is included.
