RDV-1 A complete and light weight direct vision
spectroscope without wavelength scale, for observing visible radiations
from 400 to 750 mm.
RDV-2 A compact visible spectroscope with wavelength
scale which allows the direct reading of spectral length and employs a
prism for dispersion. It is also useful for flame test of basic radicals
(sodium, strontium, potassium, copper etc.) There is a single eyepiece
and independent focussing tube for the graticule, which carries an index
at 590mm. with "D", marked right below the scale, (corresponding to the
wave length of sodium light) can be calibrated to a known light source
by adjustment of knurled screw. The amount of light admitted to the
spectroscope can be regulated by a variable slit, adjusted by a knurled
ring round the rating tube
