Description

The 650nm 5V Red Laser Diode Module HW-493 is a compact dot laser module emitting a focused 650nm red beam at 58mW transmit power, operating from 3V to 5V DC at 40mA with approximately 135mm of connecting cable for flexible mounting. The laser diode module includes an onboard APC (Automatic Power Control) driver circuit — unlike simple resistor-driven laser diodes, the APC driver continuously monitors and adjusts the diode drive current to maintain stable output power despite supply voltage fluctuations and temperature changes, extending diode lifespan and ensuring consistent beam intensity.

The laser module projects a focused point beam rather than a line — this 5v laser light module is the dot-beam counterpart to line laser modules, suited for applications requiring a precise point reference rather than a projected line. At 58mW, the 650nm laser module output power is significantly higher than typical 5mW pointer-style lasers, placing it in a higher laser safety class that demands stronger eye-safety precautions — this power level is sufficient for applications like laser tripwire security systems, optical communication experiments, and laser cutting/engraving test setups at low power, though not for actual material cutting.

APC driver circuit means this module cannot simply be PWM-dimmed like a standard LED — the APC circuit actively compensates for voltage changes, so PWM dimming techniques that work for simple laser diodes may produce unpredictable results or be filtered out by the power regulation circuit. StemVolt provides, sensors with trusted quality, ensuring reliable performance and easy usability.
