Description
With focal length 12 mm, aperture F5.6, image circle Ø9.4 mm (1/1.7"), OPT-S1256-LQL belongs to the series “M12 Liquid Lens” by OPT Machine Vision. In addition: working distance 150 mm - ∞, S-Mount (M12), spectral range 435 - 656 nm.
The M12 lenses with liquid lens combine the S-Mount format with an Optotune liquid lens (EL-3-10): focus by current, optical power from -13 to +13 dpt, fixed aperture F5.6 and an image circle for sensors up to 1/1.7". Connection is via a two-pin FPC cable. For board-level cameras and code readers that have to focus on varying distances without moving mechanics.
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.
