komparators
103
divisible radnuses of curvature 10-1000 mm . For ease of operation, the optical axis of the microscope is tilted at an angle of 45" using half a pentaprism and a rectangular prism.
Horizontal Crosscomparator-2
This device is designed for accurate measurements of lengths. It is built on the principle of a longitudinal comparator, in which the measured segment and the scale are arranged sequentially and rigidly

are interconnected. Due to its high design and operational qualities, the device finds a very wide application.
The measurement limits of the comparator ISA-2 0 200 mm, the division price of the main scale is 1 mm, the division price of the spiral ocular micrometer is 0.001 mm. A visual reading of 0.0001 mm is possible. L
The measurement error of the device is 0.9 300 - 4h) microns, where L is the measured length in mm; h is the height of the plane of the measured object above the plane of the comparator scale in mm.
Movable slides 11, sighting 8 and reference 6 microscopes are mounted on a massive base 1 (Fig. 69). On a sled
