Frequently asked questions
What sensor format does CIL924 support?
CIL924 is specified for sensor formats up to 1/2.5\" with a 6.4mm image circle.
What does +0.5% F-Theta distortion mean on this lens?
It means the lens is tuned close to F-Theta projection, with only +0.5% deviation at the 6.4mm image circle. In practice, that gives more uniform angular mapping across the image than a conventional rectilinear or strongly distorted wide-angle lens.
Is CIL924 appropriate for outdoor camera placements?
Yes. The listed mechanical version is IP67+, so it is intended for cameras that may face dust, rain, and similar environmental exposure.
Why does the all-glass, aluminum construction matter?
All-glass optics and an aluminum housing generally hold focus and alignment more consistently across temperature than lighter plastic-heavy designs. That is useful in embedded systems mounted outdoors or near heat sources.
What resolution is CIL924 designed for?
CIL924 is rated for 5MP sensors with 2.2µm pixels.
How wide is the field of view on CIL924?
The specified field of view is 156°. That places it in the wide-angle range without moving all the way to a full fisheye presentation.
