60 Day 100% money back guarantee. Industrial red laser module, model M617L3, supplied with a factory-style collimator lens for tight, adjustable beam shaping. Unit is used and produced red output during a quick bench check. No driver or power supply is included; you will need an appropriate constant-current laser driver and safe operating procedure. Photos may show an orange-looking spot in the beam center—this is a camera Bayer filter artifact when imaging narrow-band red light, not a color shift in the laser. Sold as a single module. Ideal for alignment, machine vision experiments, research fixtures, and optics labs. Ships from Carol Stream, IL USA. Dimensions: 2.5 x 2.5 x 7.0. Weight: 1.0 lb.
