Technical Selection: How to Choose the Right M12 Lens?
When selecting a manufacturer from the list above, your engineers should evaluate these four critical parameters:
- Sensor Match: Ensure the lens image circle covers your sensor (e.g., 1/1.8″ or 1/2.3″).
- CRA (Chief Ray Angle): The lens CRA must match the sensor’s microlens CRA to avoid shading.
- Resolution (MTF): Does the lens support 4K or 8K? 2026 sensors require higher LP/mm (line pairs per millimeter).
- Environmental Durability: Does the application require IP67 waterproof rating or wide temperature operation (-40°C to +85°C)?
Lens Selection Criteria by Application
