Sony IMX637 · 0.32768MP 1/4.5" CMOS image sensor
IMX637 Sensor Specifications & Compatible M12 and C-Mount Lenses
The Sony IMX637 has 640x512 pixels at 4.86µm pitch. Each pixel reports a brightness change asynchronously. Conventional frame-rate and global-versus-rolling-shutter labels do not describe this event stream. Lens selection still requires image-circle coverage, suitable focus, and contrast across the field. Dimensions are calculated from the manufacturer active pixel array: 3.1104x2.48832mm, with a diagonal of 3.983mm.

Lens selection for the IMX637
A calculated lens table is not available for this sensor. Confirm the sensor's active readout area with the manufacturer, then contact our engineers for a lens match.
How to choose a lens for the IMX637
Start from the field of view and working distance your application needs. Confirm that the lens image circle covers the active sensor diagonal and that the mount provides the required focus travel and rear clearance. A lens megapixel rating alone does not establish resolution on this sensor. Compare measured MTF at the spatial frequencies your task needs, at the intended aperture, wavelength, distance, and field position, accounting for the 4.86 µm pixel pitch. Estimate framing with the Commonlands field of view calculator.
