About this product
HW-493 is a red laser emitter module built around a 650 nm laser diode, housed in brass with an acrylic lens. It includes a built-in current-limiting resistor and runs from 5 V using only power and ground connections. Typical uses include alignment marks, optics experiments, and simple beam-based intrusion or link projects with a light-sensitive receiver.
