Description

This UV-VIS Spectrophotometer, is a rugged, cost effective, work horse type semiautomatic microcontroller based version of Spectrophotometer introduced to fill in the need for routine analysis where variation of parameters is very critical.

Principle of Operation

A selectable light beam in Ultra-violet or Visible spectrum from the Light Source gets focused on to the entrance slit of Monochromator. The incident beam of light gets tuned to push-button-settable wavelength by motorized slewing of the holographic grating and reflecting optics in Czerny-Turner mount and emerges as monochromatic light of narrow band width from the exit slit of the monochromator. Transmitted portion of this monochromatic light through the medium is detected by a wide range Photo-detector. The output of Detector-Pre-Amplifier is processed and the Absorbance / Concentration / Percentage Transmission of the medium is displayed on the Readout of the instrument.
