Description
OPT-CH20-65-F11 is a telecentric lens from the series “Cheetah Telecentric” by OPT: magnification 2.0 ×, aperture F11, image circle Ø11 mm (2/3"). In addition: working distance 65 mm ± 2 mm, C-Mount, telecentricity 0.10°.
The Cheetah series is OPT's broad telecentric range for 2/3" sensors with five megapixels: magnifications from 0.3 to 2.0×, large apertures for short exposure times, high telecentricity and high contrast. Many models are available with coaxial light coupling (C variants). It is the workhorse of optical metrology: diameters, distances, edges and hole patterns that must be measured exactly regardless of distance.
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.
