- The 228 Series Optical Wavelength Meter uses proven interferometer-based technology to measure the wavelength of CW lasers to the highest accuracy available. This performance is maintained over long periods of time with continuous calibration using a built-in wavelength standard. What’s more, features such as short measurement time, straightforward operation, and rugged design satisfy the needs of both the R&D scientist and the manufacturing engineer.
