    • High-Precision Fizeau interferometry Wavemeter     


    When paired with a high-performance, low-loss photonic crystal optical switch, the wavemeter supports simultaneous high-precision wavelength measurement of up to 8 channels. This makes it highly suitable for quantum physics experimental applications such as quantum computing and atomic clocks, which require monitoring of multiple laser frequencies.
