Microptic Universal Autocollimators
- larger aperture, giving increased maximum working distance
-2 ?/?-inch diameter telescope barrel, chromium plated and ground to permit direct mounting in vees and tooling fixures
- elemination of the image of the target draticule from the field of view
- maximum versatility
For the types 1, 3, 50, 51, 53, 57 this 4 data are the same:
- direct reading to: 0.1 second of arc
- measuring range: 10 minutes of arc
- accuracy over total measuring range: 2 seconds of arc
- accuracy over any 1-minute range: 0.5 second of arc
TA1
Microoptic Autocollimator
Displacements in two planes at right-angles are measured separately, by rotating the instrument through 90 degrees. External micrometer reading system.
maximum working distance: 50 ft
TA 3 Photoelectric Microptic Autocollimator
Displacements in two planes at right-angles are measured separately, by rotating the instrument through 90 degrees. Settings are made by rotating the external micrometer drum until a null-reading is given on a separate indicator meter.
maximum working distance: 30 ft (50 ft when used as a visual-setting instrument)
TA 53 Photoelectric Microptic Autocollimator
same as TA3, but:
Displacements in two planes at right-angles are measured separately, by rotating the eyepiece through 90 degrees.
maximum working distance: 50 ft (100 ft when used as a visual-setting instrument)
TA 50 Universal Autocollimator
Displacements in two planes at right-angles are measured separately, by rotating the eyepiece through 90 degrees. External micrometer reading system.
maximum working distance: 100 ft
+ Position of eyepiece interchangeable to permit either straight viewing, or right-angle viewing from above the intrument.
