Encapsulated in hard-coat anodized case with scratch-resistant sapphire window to protect lens, laser modules withstand harsh conditions, and are static, surge, and reverse polarity protected. They come in 635–830 nm wavelengths with standard elliptical output beam or line or cross generating optics. Laser module has optical output powers from 0.95–30 mW, operating voltage of 5 Vdc regulated ±10%, -10 to 50°C operating temperature range, and 2.5 mm dc jack/industrial screw-on connectors.
