Description
OPT-F2528-29M, a fixed focal length lens of the series “29 MP Fixed Focal Length Lenses” by OPT, comes with focal length 25 mm, aperture F2.8 - F32, image circle Ø44 mm. Also: working distance 140 mm - ∞, F-Mount.
The 29 MP series is designed for large-format sensors - 29 megapixel area scan cameras as well as line scan cameras up to 8K with 5 µm pixels. Across the full image field it reaches up to 100 lp/mm with low overall distortion. It is used when a single image has to capture large objects with high fidelity: displays, printed circuit boards, web material on line scan cameras.
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.
