On consideration of highly clear and precise dot indication for scientific research optical experiments, either pointing at close or long distance, it makes a good job to apply a TTL modulation 650nm red laser diode module. Being made with an import 650nm red laser diode, cooling system and APC, ACC driving circuit board inside a high duration metal housing tube, it achieves increasing laser beam stability, long operating time lasted red light and red dot projection stably and clearly.
TTL modulation cross linee laser mode enables correct use of output power and properly adjusted red laser dot diameter. Either used for long distance or ambient lighting occasions, highly precise and clear red laser dot is used for optical teaching demonstrations, optical path calibration, spot experiments, and photoelectric testing. Can be used as a pulse light source with high-speed switching.
