How much distortion does the CIL027 have?
The CIL027 has -1.5% TV distortion measured at 4:3 aspect ratio. That is low enough for barcode reading, dimensional measurement, and inspection without software correction.
What is the CIL027 field of view on a 1/2.3 inch sensor?
The CIL027 gives 100° horizontal field of view on a 1/2.3 inch sensor at the 6.3mm image circle. Its usable image circle extends to 7.4mm, with 9.0mm maximum.
