Bi-telecentric lenses with high numerical apertures

This bi-telecentric lens series is designed for applications where high resolution and numerical aperture is required. The advantage of the bi-telecentric design is the uniform vertical exposure of the camera sensor. Suitable mainly for sensors with microlenses as that all light enters the camera at 90 degrees (from the surface of the sensor).

The high numerical aperture enables the lens to resolve very fine details in an object. The whole series has a clear aperture of 46mm and the numerical aperture is between 0.120 and 0.180.
