Microprocessor automation of a UV-visible monochromator
Introduction Isolation of selected wavelengths of light with high resolution grating monochromators is a common operation in spectrochemical methods of analysis. Commercial monochromators and monochromator controllers are often unable to control the monochromator’s operating parameters with the resolution required in automated systems. If a monochromator is to be used in a completely automated ...
متن کاملCalibration of a monochromator using a lambdameter
The standard procedure for wavelength calibration of monochromators in the visible and near infrared wavelength range uses low-pressure gas discharge lamps with spectrally well-known emission lines as primary wavelength standard. The calibration of a monochromator in the wavelength range of 350 to 2500 nm usually takes some days due to the huge number of single measurements necessary. The useab...
متن کاملA Single-Element Plane Grating Monochromator
Concerted rotations of a self-focused varied line-space diffraction grating about its groove axis and surface normal define a new geometric class of monochromator. Defocusing is canceled, while the scanned wavelength is reinforced at fixed conjugate distances and horizontal deviation angle. This enables high spectral resolution over a wide band, and is of particular advantage at grazing reflect...
