Bristol Instruments laser wavelength meter features automatic calibration

The 871B-NIR2 laser wavelength meter measures the wavelength of lasers that operate out to 2.5 μm. These measurements have ± 0.75 ppm (±0.00075 nm at 1000 nm) accuracy and are made at a sustained 1 kHz rate. It uses a Fizeau etalon design to measure the wavelength of both pulsed and continuous-wave lasers over the 1–2.5 μm range. It features automatic calibration with a built-in wavelength standard and prealigned fiber-optic input.
