Frequently asked questions
What sensor size does CIL926 cover?
CIL926 is specified for sensors up to 1/2.5" and uses a 7.4mm image circle.
What is the distortion profile of CIL926?
It is specified as an F-theta lens with about -1.4% F-θ distortion, which is low for a 172° field of view.
What resolution is CIL926 designed to support?
The lens is rated for 5MP imaging with 2μm pixels.
Is CIL926 built for outdoor or exposed use?
Yes. The listed mechanical version is IP67, so it is intended for applications that need dust and water resistance.
Why does the all-glass, aluminum construction matter?
All-glass optics and an aluminum housing generally hold focus and alignment more consistently across temperature changes than lighter mixed-material designs.
How heavy is CIL926?
The listed weight is 12g.
