Description
OPT-COB3524 is a fixed focal length lens from the series “Cobra Fixed Focal Length Lenses” by OPT: focal length 35 mm, aperture F2.4 - F16, sensor up to 1/1.8". In addition: working distance 150 mm - ∞, C-Mount.
At Ø29 mm, the Cobra series is as slim as a compact camera and yet designed for pixels from 2.2 µm - up to 230 lp/mm across the full image field. The coating covers 400 to 1000 nm, TV distortion stays below 0.2 %, and a chief ray angle below 5° keeps the illumination uniform right into the corners. It fits wherever little space and high resolution come together: character inspection on plastic parts, chip and display inspection, particle control.
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.
Model of the first Cobra range (folder “Cobra 1” of the OPT delivery).
