Grande 635nm 650 mW High Power Laser Diode Module. The Grande laser provides up to 20 Watts of optical power for demanding applications that require high output powers. Controlled by an internal micro-processor, the design features an LCD display, which provides users safety status as well as real time information on power current settings and internal temperature. Drive current and bias settings are user controllable with 12 bits of resolution (4096 steps). The Grande features passive cooling for the circuitry and laser. Input to the module is typically 5 VDC, while blue and green lasers require 8VDC.
