Opto Engineering TC4K

Flat telecentric lenses for 4k linescan cameras

The TC4K series telecentric lenses from Opto Engineering has been designed for measurement applications using linescan cameras with a detector size up to 28.7 mm.

The flat design is ideal for applications and machines with tight dimensional constrains and, when coupled with the LTCL4K illuminators (with a matching flat design) and dedicated accessories, allow for optical combinations that fit most geometrical measurement configurations.

The TC4K series feature standard F or M42 mounts to fit common linescan camera interfaces. Moreover, the lens-camera interface provides both fine detector phase adjustment and a precise focusing mechanism. The detector phase adjustment enables precise positioning of the linear FOV at 90° from the object movement direction.
