Sill Optics TD

Bi-telecentric lenses for a wide range of applications 

The Sill Optics TD series of bi-telecentric lenses includes lenses with fixed and variable apertures. A wide range of working distances, structural shapes and magnifications are available to choose from.

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 at an angle other than the perpendicular (to the camera's sensor).
