8mm CS-Mount Lens for Up to 1/1.7" Cameras such as IMX226

The CIL080 is an 8mm CS-mount lens for 1/1.7" sensors up to 12MP, including the Sony IMX477 on the Raspberry Pi HQ camera. It gives you a 45° field of view across an 8.1mm image circle, which lands in the standard-to-portrait range instead of the exaggerated look you get from a wide lens. The fixed F/1.8 aperture also gives you useful light margin when factory or warehouse lighting is inconsistent.

The distortion is 3% TV. That is moderate, not scary. General imaging systems can usually live with it, and measurement systems can calibrate it out in software without much pain.

The optic uses all-glass elements in an aluminum housing. That combination holds focus better over temperature than cheap plastic-element lenses, and the 28g barrel has enough stiffness that the lens does not feel disposable.

The CS-mount thread makes replacement simple. You thread out the old lens, thread in the CIL080, and go back online without adapters or shims. It drops directly onto the Raspberry Pi HQ camera and Teledyne FLIR Blackfly board cameras. You can calculate your field of view.

This model does not include an integrated IR cut filter. Add an external 650nm filter for daylight-only visible imaging, or run the lens unfiltered for NIR-sensitive setups. Orders placed before 12 PM PST ship same day from San Diego, and every lens is 100% MTF tested before it leaves our facility.
