NEWTON RING MICROSCOPE COMPACT TYPE ( CAT NO. 667-ii )
This Newton ring’s microscope is compact type with built in all necessary arrangement required for conducting newton’s ring experiment . The whole microscope tube unit can be raised or lowered and can be clamped in any desired position. The focusing of the microscope unit is done by rack and pinion arrangement.
The longitudinal movement of the microscope saddle for the purpose of the Rings is done by rotating the drum. The 26 mm movement can be read by scale and on the divided drum to 0.001 cm.
Newton’s Ring set consisting of the optical flat glass and one Plano-convex Lens (50mm radius) arranged inside a metal case resting over the stage of the instrument which can be adjusted for the alignment of the measuring line . An adjustable reflector plate in the required direction is fitted on to the side of the set. The condenser lens is provided in front of the reflector.
