Question

what lamp is used asUV source in spectrophotometer

​

Answer 1

Answer:

Light Source

The radiation source is often a Tungsten filament (300–2500 nm), a deuterium arc lamp, which is continuous over the ultraviolet region (190–400 nm), Xenon arc lamp, which is continuous from 160 to 2,000 nm; or more recently, light emitting diodes (LED) for the visible wavelengths.

Explanation:

Light source The function of the light source is to provide a sufficient of light which is suitable for marking a measurement. The light source typically yields a high output of polychromatic light over a wide range of the spectrum.

Answer 2

Answer:

Light source

Two kinds of lamps, a Deuterium for measurement in the ultraviolet range and a tungsten lamp for measurement in the visible and near-infrared ranges, are used as the light sources of a spectrophotometer. A continuous spectrum of 300 - 3,000 nm is emitted.
