Frequently asked questions
What sensors work with the CIL523 16mm C-mount lens?
The CIL523 fits 2/3″ to 1.1″ sensors including the Sony IMX304 and IMX253 at 5MP with 3.45µm pixel pitch. The 11mm+ image circle covers up to 2/3″ format cleanly.
What is the field of view of the CIL523?
The field of view is 67° on a 2/3″ sensor at the 11mm image circle. That makes the CIL523 one of the wider C-mount options without giving up geometric accuracy. You can calculate exact FoV at field of view calculator
How much distortion does the CIL523 16mm lens have?
Distortion measures -0.1% from rectilinear. That number is unusually low for a 16mm C-mount lens, so software correction is generally unnecessary for dimensional measurement.
What aperture range does the CIL523 offer?
The aperture adjusts from F/1.4 to F/11.5. F/1.4 gives you maximum light throughput, and stopping down increases depth of field when you need more front-to-back sharpness.
Does the CIL523 ship same day from the US?
Yes, the CIL523 ships same day from San Diego for orders placed before 12 PM PST. Volume pricing starts at 50 units.
What is the minimum working distance of the CIL523?
The minimum working distance is 150mm to infinity. The lens weighs 64g and includes M30.5x0.5 filter threading for standard accessories.
