Low noise Laser Diode Collimator LNC-91CM flatbeam®

The laser collimator LNC-91CM flatbeam® projects a collimated laser beam with high edge intensity and minimal beam divergence. The correct choice of aperture can ensure the production of an illuminated area of almost constant lighting intensity. Applications include shadow-edge analysis and measurement methods relying upon diffraction.
