Häufig gestellte Fragen

What sensors is the CIL237 1.75mm fisheye M12 lens designed for?

The CIL237 is specified for formats from 1/3″ to 1/1.7″, and it is commonly used on sensors up to 5MP 1/2.5″ and 8MP 1/1.8″.

Why does the CIL237 page mention both 200° and 192° field of view?

Both numbers appear on the page. The product page markets the lens as 200° at 5.5mm, while the specification table lists 192° at 5.4mm image circle, so use the spec-table value for formal optical comparisons.

What is the distortion profile of the CIL237 fisheye M12 lens?

The CIL237 uses a special F-Θ distortion profile: less than 2% F-Θ through a 5.0mm image circle and -8% F-Θ at the full 5.5mm image circle.

Which lens holder should I use with the CIL237 M12 fisheye?

The CLA020 holder is one compatible mounting option for the CIL237.

Is the CIL237 compatible with Allied Vision or FLIR board cameras?

No. The page lists Allied Vision Alvium and FLIR Blackfly S Board as mechanically incompatible with the CIL237.

Are STP files available for the CIL237 200° fisheye lens?

Yes. Mechanical drawings and STP files for the CIL237 are available on request from the engineering team.

CIL237 is a cost-competitive 1.75mm fisheye M12 lens for wide coverage on larger image circles. The product page leads with 200° at 5.5mm, while the specification table lists 192° at 5.4mm image circle with a full 5.5mm image circle. In practice, this is the lens to use when you want aggressive coverage on sensors from 1/3" to 1/1.7" without moving to a much larger assembly.

The lens is rated at 5MP with 2.2μm pixels, and it is commonly used on sensors up to 5MP 1/2.5" and 8MP 1/1.8". The 1.75mm EFL, F/2.2 aperture, and 19.0mm TTL help when housing depth is still tight.

The optical design uses hybrid Glass+Plastic construction with metal mechanicals. That trade keeps cost and weight under control at 5g while still giving useful performance. The M12A variant includes BBAR on lens 1 surface 1 with a metal cap and barrel, and it is available both with IR cut and without a filter for NIR work.

The distortion profile is unusual. Commonlands calls out less than 2% F-Θ distortion through a 5.0mm image circle, then -8% F-Θ at 5.5mm. That profile is useful when angular consistency matters more than straight edges.

The recommended holder is CLA020. e-con Systems boards with 7-10mm mount height work, and iDS uEye LE Rev1.1 is compatible. Orders placed before 12 PM PST ship same day from San Diego, and mechanical drawings plus STP files are available on request.
