Frequently asked questions
What sensor format is CIL290 designed for?
CIL290 is set up for 1/2.7″ sensors and uses a 5.8mm image circle. That format matches compact 3-5MP cameras well.
How wide is the field of view on CIL290?
The CIL290 gives you a 190° field of view from a 1.9mm effective focal length. That is full fisheye territory and enough to capture nearly hemispheric coverage from one camera.
How much distortion does CIL290 have?
The lens is specified at -9% F-Theta distortion at a 5.7mm image circle. That is controlled for a fisheye this wide, and it helps keep angular behavior predictable across the field.
Is CIL290 suitable for day/night imaging?
Yes. The CIL290 is NIR corrected, so it works in day/night cameras that image in visible light during the day and near-infrared at night.
How small and light is CIL290?
The CIL290 weighs 2g and has a total track length around 12.3mm. It fits camera modules where both mass and z-height are tight.
What mechanical versions are offered for CIL290?
The lens comes in M12A and M12B versions. Both use BBAR on lens 1 surface 1, and the versions differ in barrel construction while keeping IP67 sealing.
