Optical absorption & polarised intensity measurement using photo resistor (C.R.)

Order Code: 55864

55864 Experimental Set-up has been designed specifically to measure optical absorption and polorised light intensity using photo resistor. The set-up consists of a Spectrometer, mercury light source, photo resistor, microammeter, optical filter, Batt...

SPECIFICATION

The set-up is complete in all respect and requires no other apparatus.

OBJECT

To study the variation of light intensity from a Poloriser and Analyser combination.(Using photo resistor as a detector)
To estimate the absorption coefficient and transmission coefficient of various optical filtters using a photo resistor as detector.

FEATURES

The complete Experimental Set up consists of the following :

SPECTROMETER STANDARD : 6" dia circle reading 30 seconds. The objectives used in telescope and collimator are achromatic and provided with rack and pinion focussing arrangement. Telescope arm and prism table are provided with fine and coarse adjustment. The prism table is provided with three leveling screws and is engraved with concentric rings & lines. The scales and verniers are of stainless steel and are machine divided. Clamping devices are also provided to lock telescope and collimator after adjustment, with prism clamping device and diffraction grating stand.
