1660. Vernier Microscope "RAC"
A Sturdy special instrument designed for a wide variety of uses in
the laboratories.
The Bed is a heavy box casting well seasoned and carries the

The Scale fitted to the bed along the carriage, is machine divided
on lifetime stainless steel. Range of division ±.001 %.
A Vernier is sprung fitted to the carriage and gives the least count
of .01, .005. .002 or '001 cm as specified while ordering (In the
absence of any specific instructions, .001 cm is supplied). The
Spring fitting of the vernier permits its fine apposition to the
scale.
The Microscope can be adjusted to any horizontal or any vertical
position with reference to the scale. Rack and Pinion focusing,
provided with 10x Ramsden Eyepiece, cross line reticule with 2" or
3" focusing distance achromatic objective
Cross Motion: Cross motion is provided to determine the young's

The longitudinal movement of the Microscope saddle for the purpose
of the Rings is done by rotating the drum provided.
The 26 mm. movement can be read by scale & on the divided drum to
0.001 cm. Newton's Ring set consisting of one optical flat glass and
one plano convex lens arranged inside a metal case resting over the
stage of the instrument can be adjusted for the alignment of the
measuring line. A reflector plate adjustable in the required
direction is fitted on to the side of the set. The condenser lens is
provided in front of the reflector.
