tungsten filament lamp that can be made to either manually or automatically replace the deuterium
lamp when the wavelength programmer has reached the appropriate transmission wavelength.
The UV/Visible Dispersive Spectrometer
A diagram of the optical system of a UV/Visible Dispersive Spectrometer is shown in Figure 2.3

The Multiwave Length Dispersive Spectrometer-Detector
Light from the deuterium discharge lamp is collimated by two curved mirrors onto a holographic
diffraction grating. The dispersed light is focused, by means of a curved mirror, onto a plane mirror and
the light of the required specific wavelength selected by adjusting the angle of the plane mirror. Light of
the selected wavelength is then focused by means of
