Scanning spectrophotometer
WebSep 12, 2024 · Schematic diagram of a scanning, double-beam spectrophotometer. A chopper directs the source’s radiation, using a transparent window to pass radiation to the sample and a mirror to reflect radiation to the blank. The chopper’s opaque surface serves as a shutter, which allows for a constant adjustment of the spectrophotometer’s 0%T. WebThe basic elements of a monochromator are (1) entrance slit, (2) collimating mirror (to form a parallel beam after the slit), (3) diffraction grating (dispersive element), (4) camera …
