GH0641FA2G Sharp 642nm 150mW Red Laser Diode 5.6mm Package
This SHARP red laser diode is a precision-engineered visible-light source, tailored for applications that demand stable, focused emission. Operating at a typical 642nm wavelength, it delivers a reliable 150mW continuous-wave (CW) optical output — making it an excellent choice for displays, barcode scanners, laser sensors, and a range of other optical systems.
A key highlight of this diode is its single transverse mode oscillation, which ensures tight, consistent beam quality — critical for precision tasks like barcode scanning or sensor calibration. It comes packaged in a compact Ø5.6mm CAN form factor, balancing small size with robust performance to simplify integration into space-constrained designs.
In terms of operational reliability, it supports a 155mW maximum CW output (at 25°C case temperature, adjusting to 130mW at 40°C) and a 2V reverse voltage. It functions across a -10 to +60°C operating temperature range and withstands -40 to +85°C during storage, with a 350°C maximum soldering temperature (under specified conditions) for easy assembly.
Whether powering high-precision scanners, compact displays, or sensitive laser sensors, this SHARP 642nm diode combines single-mode clarity, consistent 150mW output, and durable packaging — a trusted solution for both consumer and industrial optical applications.
