Field of View on the Sony IMX226 by Focal Length
| Lens | EFL | Max aperture | HFOV × VFOV on the IMX226 | Distortion | Image circle | Price |
|---|---|---|---|---|---|---|
| CIL560 | 4mm | F/2.8 | 89° × 72° | -5% | 9.3mm | $199.00 |
| CIL561 | 6mm | F/2.4 | 65° × 51° | -2% | 9.3mm | $149.00 |
| CIL562 | 8mm | F/2.4 | 50° × 39° | -0.2% | 9.3mm | $149.00 |
| CIL563 | 12mm | F/2.4 | 35° × 26° | -2% | 9.3mm | $149.00 |
The Commonlands FOV engine computes these horizontal and vertical angles for the IMX226 active area rather than for the full image circle, so they run narrower than the diagonal figure on each product page. Run a different sensor through the field of view calculator before you order.
Which Cameras Use the 1/1.7" Format
The Sony IMX226 is the 1/1.7" sensor camera makers ship most often in this class: 4072 by 3046 pixels at 1.85µm with a rolling shutter. Basler builds it into the ace acA4024-29um, IDS into the uEye CP and SE families, and The Imaging Source into the 33UX226 cameras.
Commonlands rates the CIL560 through CIL563 for the IMX226, and smaller 12MP sensors such as the 1/2.3" IMX477 and IMX577 also sit inside the 9.3mm image circle with a narrower field of view. A 2/3" sensor like the IMX264 needs the 2/3" 5MP or 2/3" 12MP series instead.
For the image-circle rules behind these pairings, read the Commonlands guides to sensor size and lens compatibility and image sensor selection for machine vision.
How to Choose a Focal Length for the IMX226
Start from the field you must cover at your working distance, then take the longest focal length that still fits it. Commonlands lists the horizontal field on the IMX226 in the table above, from 89° with the 4mm lens down to 35° with the 12mm.
Stopping the iris down buys depth of field when parts sit at different heights, and machine vision lighting is usually programmable, so the lost exposure is cheap to recover. Check the depth of field calculator before you lock the aperture.
Working Distance and Minimum Focus on 1/1.7" Lenses
Working distance varies by product, typically 100mm to infinity for Commonlands C-mount lenses, and each product page lists the minimum focus distance. The working distance guide explains how the internal cam refocuses these designs and why the minimum object distance is a hard stop.
Depth of field shrinks fast at short standoffs, so pick the aperture with the depth of field guide before you fix the camera height. Short focal lengths such as the 4mm and 6mm reach wide fields from close range; the 12mm keeps more standoff for the same field.
What the 12MP Rating Means at 1.85µm
The 12MP label names the sensor class Commonlands designed and toleranced these lenses for, not a measured resolving power. Ask for the MTF curve at your aperture, field height, and wavelength band, and compare it against the 1.85µm pitch of your sensor.
All four designs are all-glass optics with an adjustable iris. The CIL562 and CIL563 take M27×0.5 front filters, which matters if you plan to add an IR-cut or bandpass filter from the Commonlands optical filters collection.
