Direct Vision Spectroscope Laboratory Equipments Supplies Description and Specifications for Lab Tenders
Product description:
A complete and light weight
direct vision spectroscope without wavelength scale, for observing
visible radiations from 400 to 750 mm.
B 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
focusing 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..
