Description

High-power, monochromatised UV source for the study of nanostructures. This product uses Bragg diffraction to separate a narrow band of light wavelengths. During crystal rotation, the user can find four different wavelengths of beam transferred to the sample. This happens because each wavelength is reflected by crystal at different angles (Bragg reflection). ZERO ORDER beam is created when monochromator crystal works similar to a normal mirror – it reflects multiple wavelengths and gives highest intensitivity of transferred beam. That mode can be used when the user does not need monochromated beam, but high intensitivity of UV radiation.
