Colimatoare laser 635nm 1.25" & 2"

A precision-machined alignment tool for 1.25 and 2-inch apertures

• This graceful laser collimator is practically indestructible. The laser diode module is held in place by paired setscrews from four compass points, ensuring true alignment, even after repeated dropping.
• The combination of a 635 nm, bright red laser diode with an 0.8 mm aperture stop resuilts in a small, easily visible impinging point for precise collimation.
• An aluminum ring protects the on/off switch from inadvertent power cycling and thus empty batteries.
