The 635 and 650-nm versions of the laser modules have outputs of 3, 5, and 7 mW. The lasers feature automatic power control with soft-start protection, as well as three-element glass collimating-lens with AR coating. Operating voltages range from 4.5 to 9 Vdc, but 5 V is the recommended rate within a temperature range from 10 to 4°C. Housing is of a durable anodized aluminum. A green LED in the rear of the unit confirms laser emissions.
