Product Details: WA-1600 W***emeter systems are instruments designed for simple, automatic and accurate w***elength measurement of continuous w***e (CW) laser sources. W***emeter systems count interference fringes produced by the input laser radiation in a scanning Michelson interferometer and simultaneously count fringes from a built-in reference laser. The ratio of the fringe counts of the input laser and the reference laser provides the w***elength of the input laser. |
