This visible laser emits at 670 nm and can be operated with a battery or AC-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 screwdriver for elevation and pitch adjustments. • Battery or external power supply operation • Compact, weatherproof design • Built-in screws for fine beam direction adjustment • Output power >1 mW • Minimal beam divergence and beam drift • Highly stable output power • Precision optical system alignment • System reference beam Specifications Wavelength (nm) 635 Beam Diameter (1/e2) 3.7 mm x 1.9 mm at 1 m distance Beam Divergence Full Angle (mrad) <0.5 Beam Drift, Long Term (ìrad) <1 Power Stability, 1 hr (ìW) ±5 Dimensions [in.
