Frequently asked questions

What sensors work with the CIL534 25mm C-mount lens?

Supports 2/3″ sensors up to 12MP with 2.2um pixel pitch. Sony IMX487 and IMX536 are standard matches, and the >11mm image circle covers the full 2/3″ format.

Does the CIL534 really have 0% distortion?

Yes. The CIL534 measures 0% from rectilinear at minimum object distance. That makes it a strong option for precision measurement and gauging where geometric accuracy cannot drift.

What is the minimum working distance for the CIL534?

The CIL534 focuses from 200mm to infinity. For shorter working distances, look at the 12mm CIL532 or 16mm CIL533, which focus down to 150mm and 100mm respectively.

Can I adjust the aperture on the CIL534 25mm lens?

Yes. The aperture adjusts manually from F/2.0 to F/16. Use https://commonlands.com/pages/camera-depth-of-field-calculator to pick the right setting for your working distance and required depth.

How does the CIL534 compare to the CIL514 25mm C-mount lens?

The CIL534 covers 2/3″ sensors (>11mm image circle, $149) while the CIL514 covers larger 1.1″ sensors ($249). If you are using a 2/3″ camera, the CIL534 is the cost-effective choice.

Does the CIL534 ship same day from the US?

Yes. Orders before 12 PM PST ship same day from our San Diego warehouse. Volume pricing is available. Contact Commonlands for quotes on quantity orders.

The CIL534 is a 25mm C-mount lens for 2/3" sensors at 12MP resolution with 2.2um pixel pitch. It covers sensors including the Sony IMX487, IMX536, and comparable 2/3" imagers. Adjustable aperture from F/2.0 to F/16 gives you precise control over depth of field.

Distortion is 0% from rectilinear at minimum object distance. Rare in this price class, and exactly why the lens is strong in dimensional measurement, gauging, and precision metrology. The 26° field of view gives tight framing, while the >11mm image circle covers the full 2/3" sensor format without vignetting. Check field coverage at https://commonlands.com/pages/camera-field-of-view-calculator.

All-glass optical construction in a 50g barrel. The lightest lens in the CIL53x C-mount series. M25.5x0.5 front thread accepts standard filters. Finite conjugate optimization from 200mm to infinity keeps corner sharpness consistent across the working range, which is not always true of infinity-only designs.

Standard C-mount interface (17.526mm flange distance) fits cameras from Basler, FLIR, Lucid Vision, Allied Vision, and other industrial camera manufacturers. The 25mm focal length is a common choice when the job needs moderate magnification for quality inspection, character recognition, or precision assembly verification. More on the mount is at https://commonlands.com/pages/lens-mounts-101.

Available as CIL534-F2.0-CMANIR (without filter). Ships same day from San Diego for orders placed before 12 PM PST. Contact our optical engineering team for volume pricing, Trioptics MTF data, and .STP mechanical files.
