In the spectrophotometer, light from the Halogen Lamp is focused on the entrance slit of

the Monochromator where the collimating mirror directs the beam onto the grating. The

grating disperses the light beam to produce the spectrum, a portion of which is focused

on the exit slit of the Monochromator by a collimating mirror. From here the beam is

passed to a Sample Compartment through one of the filters, which helps to eliminate

unwanted second order radiation from the diffraction grating. Upon leaving the Sample

Compartment, the beam is passed to the silicon photodiode Detector and causes the

Detector to produce an electrical signal that is shown on the Digital Display window.
