The 500-010001 from The Optoelectronics Company Ltd is a Diode Laser that operates at a wavelength of 639 nm. It delivers an output power of 5 mW and has a power stability of 5%. This laser produces a beam of diameter 4 mm x 2 mm and has a beam divergence of 0.6 mrad x 0.3 mrad. It has a beam pointing stability of up to 0.2 mrad/^oc and bore sighting below 2^o (half-angle). This laser consists of a laser diode, an aspherical AR-coated glass lens, self-contained drive electronics, and externally adjustable optics. It requires a DC supply voltage of 5 V and consumes 50 mA of current. This laser is available in a compact anodized aluminium housing that measures Ø12 mm x 53 mm and is ideal for industrial & medical alignment, industrial inspection, sensing, positioning, and low-level laser therapy applications.
