A precision-machined alignment tool for 1.25 and 2-inch apertures, this graceful laser collimator is practically indestructible. The 632nm, bright red laser diode is held in place by paired setscrews from four compass points, ensuring true alignment, even after repeated dropping. An aluminum ring protects the on/off switch, helping to prevent inadvertent power cycling. The laser is filtered by a .8mm aperture stop at the business end of the collimator. Rugged, yet smooth, this tool fits nicely into the palm of your hand, and will provide years of trouble-free, accurate mirror alignments.
