Wavelength meter
The Model WA-2500 Wavemeterjr uses a Michelson interferometer to measure CW laser wavelengths from 400 to 1800 nm to an accuracy of ۫ part in 104. The instrument comes with both fiberoptic coupling and an RS-232 data interface. Wavelength measurements from beams with powers as low as 20 µW can be made.
