PHYSICS, Class XII, Part-2,Chapter-9, Ray optics & optical instruments.
The theory of the prism spectrometer indicates that a spectrum of maximum definition is obtained when the angular deviation of a light ray passing through the prism is a minimum.

SPECTROSCOPE (DIRECT VISION)
PHYSICS, Class XII, Part-2,Chapter-9, Ray optics and optical instruments, Dispersion by a Prism.
It is used to observe dispersion of light. Body made of brass. Supplied in wooden case. Length : 100 mm.
SPECTROMETER STUDENT
PHYSICS, Class XII, Part-2,Chapter-9, Ray optics and optical instruments, Dispersion by a Prism.
It is used for quantitative light experiments. The collimator is fixed on the base and the telescope can be rotated. Concealed helical focusing is provided on the telescope and collimator tubes. The collimator slit has spring loaded jaws. The graduated prism table has a vernier attached which is fixed on the telescope arm. The prism table is adjustable with the help of 3 knurled screws and it has screwed holes for attaching prism & grating holder.
