WAVELENGTH METER Bristol Instruments Inc. has introduced model 521, a laser wavelength meter that uses Michelson interferometer-based technology to measure the absolute wavelength of most continuous-wave lasers with an accuracy of ±10 pulses per minute (±0.01 nm at 1000 nm). An integrated moiré scale serves as a reference to provide continuous calibration. Two versions are available: one operating from 350 to 1100 nm, and the other, from 500 to 1700 nm. A prealigned optical fiber input accepts the laser under test, and measurements are made at a rate of 10 Hz. A USB interface is included.
