The LH series laser modules features: Shock resistant design. A single element glass collimating lens that provides good beam quality and low divergence. A ball joint rear end, so when placed in a tube, the output end can be steered for beam alignment. Automatic power control (APC) circuitry that regulates the output power over their entire input voltage range. Reverse polarity protection. NOTE: The case of the laser module and the positive input lead are electrically common. Specifications: Power output: 4.5mW typical Wavelength: 635nm RED Note: This wavelength laser will appear twice as bright to the eye as a 650nm laser of the same power. Beam diameter: 1mm x 3.8mm Beam divergence: 0.4mRadians Collimating lens: 1 element glass Input voltage & current: 3 to 6 VDC, 40mA Input leads: Red lead positive, Black lead negative. Operating temperature: up to 50 deg. C Housing material: Brass Dimensions: .375″ dia. x .65″long, 9.5mm dia. x 16.5mm long
