The QL63D43A/B from Quantum Semiconductor International is a Continuous Wave Red Laser Diode that operates at a wavelength of 635 nm with a slope efficiency of 0.65 mW. This single transverse laser diode delivers an optical output power of 5 mW. It has a parallel beam divergence of 8 degrees and a perpendicular beam divergence of 34 degrees. This QL63D43A/B requires a threshold current of 21 mA, an operating current of 30 mA, and a reverse voltage of 30 V. It is available in a 3.3 mm TO-Can package and is ideal for optical leveler, laser module, and bar code reader applications.
