WebA monochromator is an optical instrument which measures the light spectrum. Light is focused in the input slit and diffracted by a grating. In this way, only one color is transmitted through the output slit at a given time. Spectra are then recorded wavelength by wavelength, rotating the grating. WebUsing Type IV aberration-corrected monochromator Gratings, a single concave grating disperses, collimates and refocuses the light from the entrance slit onto the exit slit. Wavelength scanning is obtained through a simple rotation of the grating. The groove spacing of these gratings is computeroptimized to produce high quality images ... Data … changing an immersion heaterWebThis grating monochromator is grey, made of metal, and trapezoidal in shape. It has three silver knobs - drum micrometers - which can be used to manually adjust various settings. The knob on top is likely used to adjust wavelength and the knobs on the sides of the object (marked in milimeters) are likely used to adjust slit openings. changing an led light bulb
