views updated

monochromator In reflected-light microscopy, an accessory used to observe the optical properties of minerals with incident light of a specific wavelength. Fixed monochromatic interference filters with a band width of 15–50 nm and continuous-spectrum monochromators are available. They are used primarily for reflectance measurements at specific wavelengths, normally 546 to 589 nm.
