Low Distortion 5.2mm M12 Lens for up to 1/1.8" Sensors such as AR2020

CIL052 is a 5.2mm low-distortion M12 lens for sensors up to 1/1.8" format, resolving 16MP+ at 1.4µm pixel pitch. Rectilinear distortion is -0.1% measured at the 7.2mm image circle. That number is why engineers use this lens for barcode reading, measurement, and PCB inspection where straight lines need to stay straight without software correction.

The 9-element all-glass design gives you a 70° field of view at a fixed F/3.4 aperture. The image circle is 9.0mm as designed and 9.2mm maximum, which leaves margin on 1/1.8" sensors. For the ON Semiconductor AR2020 and similar 16MP sensors, the lens is a direct optical match. The lens weighs 13.1g, and the 12° chief ray angle at 8.9mm works with most BSI CMOS microlens arrays.

The M12A variant uses BBAR coating on the first surface but has no IP rating. You can order CIL052-F3.4-M12A650 with the 650nm IRC filter, CIL052-F3.4-M12ABP850 with an 850nm bandpass for NIR, CIL052-F3.4-M12ANIR without a filter, or CIL052-F3.4-M12B650 in the IP-rated M12B barrel. The IR cut filter is optional across the line.

The lens is compatible with the Commonlands CLA024 lens holder. e-con Systems boards need a 12–15mm tall mount. D3 Engineering, Allied Vision, Basler Dart, and The Imaging Source M12 cameras are compatible. iDS XLS and Raspberry Pi HQ are not mechanically compatible. You can check field of view calculator for angular coverage on your sensor.

The lens ships same day from San Diego for orders before 12 PM PST. Mechanical drawings and STP files are available on request. You can see depth of field calculator for depth of field at your working distance.
