IMX487やIMX250など、最大2/3インチセンサー用の16mm Cマウントレンズ

The CIL533 is a 16mm C-mount lens for 2/3" sensors resolving 12MP and above at pixel pitches down to 2.1um. It covers sensors like the Sony IMX487 and IMX250 with an 11mm+ image circle, and the iris adjusts from F/2.0 to F/16. This is the focal length that usually works when 12mm still looks too wide and 25mm starts to feel cramped.

The CIL533 measures -0.1% from rectilinear at 0.5m working distance. That is low enough that most machine vision systems can skip distortion correction and keep measurement math simple. The 37° field of view keeps per-pixel detail high while still covering a practical area for part inspection and conveyor monitoring. You can check coverage at field of view calculator

The optical design uses all-glass elements in a compact 63g barrel, and the front takes M27x0.5 filters. Focus runs from 0.1m to infinity, so the lens works in both close inspection cells and longer-range factory setups. The design also resolves pixel pitches as fine as 2.0um at F/2.0, which gives some margin for current high-density 2/3" sensors.

The standard C-mount thread and 17.526mm flange distance let the lens fit Basler, FLIR, Lucid Vision, Allied Vision, and similar industrial cameras directly. The mechanics are straightforward, and the 16mm focal length is straightforward to deploy because it rarely pushes the system into optical extremes.

The CIL533 is available as CIL533-F2.0-CMANIR without a filter. All in-stock units ship the same day from San Diego when you order before 12 PM PST. Volume pricing and STP mechanical drawings are available through our US-based optical engineering team.
