The wavelength meter precisely characterizes the wavelengths of cw lasers in the spectral range of 400 nm to 1800 nm.
According to the principle of the "scanning" Michelson interferometer, the unknown laser beam is permanently compared with the integrated He-Ne reference laser. Due to the high system measuring rate of 8.3 Hz, the measuring results are evaluated and displayed virtually under real-time conditions.
The resulting wavelength is calculated in separate, microprocessor-controlled evaluation electronics and output on the LED display as wavelength, wave number
or frequency. The integrated IEC interface allows the data to be additionally evaluated and displayed via PC.
