The Newport Gas and Vapor Reference Cells are offered in various configurations and elements, and will create a molecular absorption at specific wavelengths when used in conjunction with a broadband light source. They are an intrinsic wavelength reference standard for any spectral based measuring device or instrument. See reference table below for descriptions and absorption lines for each gas type.
