Description
With focal length 35 mm, aperture F2.8 - F16, image circle 1.1"(17.6mm), OPT-CDP3528 belongs to the series “Dolphin 20 MP Fixed Focal Length Lenses” by OPT Machine Vision. Further key data: working distance 200 mm - ∞, C-Mount.
The Dolphin series is designed for 20 megapixel cameras with pixels from 2.4 µm and sensors up to 1.1" (Ø17.6 mm) and reaches up to 208 lp/mm across the entire image field. A chief ray angle below 5° ensures uniform illumination without edge fall-off; the coating covers 400 to 1000 nm. It is the first choice for high-resolution area scan cameras of the 1.1" class in electronics, battery and precision inspection.
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.
