Description
OPT-CDP1228 is a fixed focal length lens from the series “Dolphin 20 MP Fixed Focal Length Lenses” by OPT: focal length 12 mm, aperture F2.8 - F16, image circle 1.1"(17.6mm). Also: working distance 100 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.
