Monochromators
The monochromator slit width used in a spectrophotometer is expressed not as the slit width dimension but as the value of the resolution achieved. Setting the slit
The monochromator contains an entrance slit, a dispersive element (usually a diffraction gratin or a prism) and an exit slit. Typically the widths of the entrance and exit slits are fixed for a given ...
