Wavelength calibration glass is a high-precision standard optical material specifically used in spectral analysis and optical instruments. It possesses known and accurate spectral characteristics and is commonly used to calibrate the wavelength resolution and accuracy of spectrometers, spectral analyzers, laser equipment, and other optical measurement systems. By using wavelength calibration glass, the accuracy and consistency of the measurement results of these devices can be ensured.
