The Co-ordinate Measuring Microscope is characterized by carefully lapped micrometer screws and nuts provided with compensating spring device to eliminate back-lash and to minimize its development after prolonged use.
The linear carriage, carried on a rugged and aged cast frame, is provided with Micrometric motion through its entire 20 cms. Range, read to 0.0001 cm directly on the Micrometric head. Micrometric heads are made of gun metal. A compensating spring device minimizes development of back-lash after constant use over a long period. The machined opposing surfaces of the carriage and the frame and inter ground to give an oil smooth movement free from any lateral shift.
The cross carriage is carried on the linear slide and has a range of 10 cms. Read directly to 0.0001 cm on the micrometer head.
The lifetime stainless scales are precision machine divided on the latest machines to give maximum accuracy. Micrometer drum heads are of large dia divided to read directly to 0.0001 cm.
The microscope tube is provided with rack and pinion focusing and is fitted with finest achromatic optics. The instrument is supplied with 3” objective and 10 x Ramsden eyepiece with cross line graticule. Supplied in wooden box but W/O any accessories.
