Frequently asked questions
What sensors does the CIL436 zoom M12 lens support?
The CIL436 covers 1/2.7″ sensors at up to 2MP with 3μm pixel pitch and projects a 6.7mm image circle. That is the sensor class it was built around.
How much zoom range does the CIL436 provide?
The lens gives about 2.5-3X optical zoom from 4mm to 9mm EFL. At 4mm, it reaches 141° FoV and then narrows toward a normal field at 9mm.
Is the CIL436 compatible with FLIR Blackfly S cameras?
Yes. The CIL436 is mechanically compatible with FLIR Blackfly S, Allied Vision Alvium S-mount, The Imaging Source M12, and Basler Dart S-mount cameras.
What is the distortion on the CIL436 at the wide end?
At 4mm, the lens is specified at -65% distortion. That is very high, so a fixed-focal low-distortion lens is the better choice if geometry matters at the wide end.
Does the CIL436 come with an IR cut filter?
Yes. You can order CIL436-F2.0-M12A650 with a 650nm IRC filter or CIL436-F2.0-M12ANIR without the filter for NIR or dual-band work.
Does the CIL436 M12 zoom lens ship from the US?
Yes. Orders placed before 12 PM PST ship same day from the San Diego warehouse.
