Flat telecentric illuminators for 4k linescan cameras

LTCL4K telecentric illuminators are specifically designed for use with the TC4K telecentric lenses, in order to provide the high optical throughput needed for high-speed linescan measurement applications.

These illuminators are equipped with state-of-the-art LED driving electronics, providing exceptional illumination stability, precise light intensity tuning and easy replacement of the LED source.

The flat shape, when coupled with the flat telecentric TC4K lens, enable the whole configuration to be easily integrated into constrained spaces.
