HL6388MG 638nm 250mW Red Laser Diode 5.6mm Package

HL6388MG 638nm 250mW Red Laser Diode 5.6mm Package The HL6388MG stands as a robust, high-performance visible laser diode engineered for demanding optical applications. Crafted with a multi-quantum well (MQW) AlGaInP structure optimized for the 0.64µm wavelength band, it delivers bright, consistent 638nm red light (with a typical range spanning 632–642nm) — making it an exceptional choice for laser shows, professional displays, and a wide array of optical equipment. Designed to balance power and versatility, this diode outputs up to 200mW of continuous-wave (CW) optical power (operating safely within its 250mW maximum rating), ensuring vibrant, visible emission suitable for both entertainment and industrial use cases. Its multi-transverse mode operation enhances light stability, even in dynamic environments, while its compact Ø5.6mm package simplifies integration into space-constrained designs, from portable projectors to custom light systems. In terms of performance, the HL6388MG operates efficiently: it reaches a threshold current of just 110mA (typical) and runs at a nominal 360mA operating current (at 200mW output), paired with a low 2.3V operating voltage — minimizing power draw without sacrificing output quality. Its beam divergence (10° parallel to the junction, 40° perpendicular) ensures flexible beam shaping for targeted or wide-area illumination.
