Data sheet Gas laser (He-Ne) 2 mW


Metal / glass-welded tube with cathode specially treated to ensure an increased long-time strength (15 000 H) and a storage without maintenance. Collimation lenses at the mirror's front side producing a small-diameter beam. A low divergence enables the beam to remain fine. Coaxial laser tube providing stability in the power and direction to carry out reproductible quantitative recordings (spectrophotometry, for ex.). Built-in 230 V power supply for an easier experiment's putting into service and the equipment storage. Supplied with instruction booklet.
