Frequently asked questions
What sensor format is CIL825 designed for?
CIL825 is specified for sensors up to 1/2.5" and uses a 6.4mm image circle.
How much distortion does CIL825 have?
The lens is specified at -11% TV distortion in 4:3 format at a 6.0mm image height.
Is CIL825 a fisheye lens?
Not in the usual full-fisheye sense. It is a 2.5mm wide-angle lens with stereographic rendering and a 115° field of view, so the image looks more natural than a typical fisheye.
What resolution can CIL825 support?
It is rated for 6MP imaging with 2.2μm pixel sizes.
How heavy is CIL825?
The listed weight is 4g, which is useful for lightweight board cameras and compact housings.
