SYLVINE Lens 0.03/0.25x C-Mount

SYLVINE telecentric lenses provide bilateral telecentricity for precise dimensional measurements and high-resolution micro-inspection down to 2.4 µm pixel size. Designed for 2/3” sensors with magnifications from 0.2x to 1x, they ensure consistent image position even with slight defocusing or sensor misalignment.

This bilateral telecentric 2/3" C-Mount lens for 0.25x magnification is a precise instrument for accurate dimensional measurement and high resolution micro inspection. The special telecentric design is the key for easy inspection of holes and tubes. Telecentricity not only on the object but also on the sensor side keeps the image position even with slight defocussing or sensor misalignment. Typical applications: High precision measurement, tube inspection, jewel inspection, micro defect detection.
