Description
With focal length 35 mm, aperture F4.5 - F32, image circle Ø44 mm, OPT-M3545-78M belongs to the series “78 MP Fixed Focal Length Lenses” by OPT Machine Vision. Also: working distance 100 mm - ∞, M58.
The 78 MP series serves full-frame sensors up to Ø44 mm with pixels from 3.2 µm and resolves up to 160 lp/mm across the entire field. The coating covers 400 to 1000 nm, and the floating focus secures the performance over a wide working distance range. Intended for cameras of the 60 to 80 megapixel class in semiconductor, display and precision measurement.
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.
