Sill Optics TDL

Bi-telecentric lenses for large sensor sizes 

The TDL series of bi-telecentric lenses is designed for applications with larger camera sensor sizes ranging from 30 mm to 70 mm length. The series has a clear aperture between 63 mm and 133 mm and a magnification range from 0.461 up to 1.0.

The advantage of the bi-telecentric design is the uniform vertical exposure of the camera sensor. Suitable mainly for sensors with microlenses so that no light enters the camera at an angle (from the perpendicular).
