IMX487 및 Sony IMX536과 같은 최대 2/3" 센서용 25mm C-Mount 렌즈

The CIL535 is a 35mm C-mount lens for 2/3" sensors resolving 12MP at 2.2um pixel pitch. It is the longest standard focal length in the CIL53x 2/3" series, and it gives you a tight 16° field across the >11mm image circle. Sensors like the Sony IMX487 and IMX536 are direct fits.

The CIL535 measures -0.1% from rectilinear at minimum object distance. That low distortion, combined with the narrow field, makes the lens a strong match for precision gauging, OCR at distance, and detail inspection when you need the target to fill the frame. The iris adjusts from F/2.0 to F/16, which matters because long focal lengths punish shallow depth of field quickly. You can model the tradeoff at depth of field calculator

The lens uses all-glass optics in a 63g barrel with an M25.5x0.5 filter thread. Focus runs from 150-200mm to infinity. The finite conjugate optimization keeps the field sharp at close working distances instead of only cleaning up at infinity, which is important in the 200-500mm standoff range where many inspection systems operate.

The standard C-mount thread and 17.526mm flange distance let the lens drop straight onto cameras from Basler, FLIR, Lucid Vision, Allied Vision, and similar industrial platforms. If 35mm is too tight for the station, you should step down to the CIL534 at 25mm or the CIL533 at 16mm. You can compare coverage at field of view calculator

The CIL535 is available as CIL535-F2.0-CMANIR without a filter. All in-stock units ship the same day from San Diego when you order before 12 PM PST. Contact our US-based engineering team if you need volume pricing, STP files, or Trioptics MTF test data.
