228B OPTICAL WAVELENGTH METER
Description
The 228 Optical Wavelength Meter uses a proven optical interferometer-based design to measure the wavelength of CW lasers to the highest accuracy available. Two versions are offered. The model 228A is the most accurate, measuring wavelength to an accuracy of ± 0.3 pm. For less exacting test requirements, the model 228B is a lower-priced alternative with a wavelength accuracy of ± 1.0 pm.
