Maximum compatibility for 1.1 (18.4mm) inch sensor cameras.
This series has two options: coaxial and non coaxial. Coaxial lenses can provide more uniform illumination than traditional light sources, while non coaxial telephoto lenses have the characteristics of low distortion, high telecentricity, and high depth of field, both of which are suitable for high-precision measurement.
Standard lens interface C, other interfaces can be customized.
