SPECTROMETER
Model RH-221 |
A
robust instrument designed to give maximum accuracy consists
of a telescope & a collimator , mounted on a stable heavy
C.I. base with three levelling screws. The protected 150mm(6.0”)
scale divided into 0-360 degrees in steps of half degrees
can be read from both sides & moves along with the telescope
to give its exact position.It gives accuracy of one minute
of an arc or 30 second of an arc. The telescope is fitted
with 175mm(7.0”) focus achromatic objective having clear
aperture of 25mm & a Ramsden eyepiece with cross line
graticule. The free moving telescope can be fixed at any position
by a screw & fine adjustment for final reading be done
by micrometer screws. The collimator is also fitted with 175mm
objective & adjustable precision slot with jaws of non-rusting
metal. Both the telescope & the collimator are having
fine rack & pinion motion. In the center of the table
there is a prism table for clamping of prism or diffraction
grating. The instrument is supplied in a thick & attractive
plywood box.With Stainless Steel scale.
