The LOA Series Alignment red laser is designed to easily mount onto 1-inch mounts with its ring adaptor and provide exceptional power and beam-drift stability with very small beam-divergence. This visible laser emits at 635 nm and can be operated with a battery or AC to DC power adaptor. This Class IIIa laser is only 92 mm long and constructed of aircraft aluminum (6061T) with weatherproofing seals to make it a lightweight, robust, portable tool for laboratory or field use. The LOA-1 comes with a 6 V alkaline battery while the LOA-2 has an external power supply. Each includes a 1-inch optical mount adaptor and Allen hex wrench for elevation and pitch adjustments.
