83 Alignment Telescope

As our most versatile alignment scope, the model 83 incorporates two micrometers for precise measurements in two directions perpendicular to the line of sight. The telescope has built-in provisions for maintaining the line of sight straight throughtout a focusing range of tow inches to infinity, allowing the instrument to be located in the tightest of setups. Straightness is maintained at ±0.001 of an inch from two inches to 17 feet and one arcsecond from 17 feet to infinity. Model 83 is also equipped for autocollimation and auto-reflection.

83-1 Alignment Telescope

The Brunson model 83-1 alignment telescope has the same capabilities as the 83 with the addition of a right angle eyepiece. The eyepiece swivels 360 degrees for ease of viewing from any angle.

82 Alignment Telescope

The Brunson model 82 alignment telescope has the same physical configuration as the 83, without the micrometers. This unique feature produces an economical linescope that is compatible with the popular Brunson spherical mounting system.

Telescope:

81 Alignment Telescope

Whether it is employed in complex, multi-instrument setups or simply holding a reference line, the 81 is an economical and reliable optical alignment instrument. This scope is well-suited to applications not requiring micrometer measurements.






81 Specifications

Telescope:

381 Alignment Telescope

Functionally similar to the larger model 81, the 381's compact size results in affordability without compromising accuracy. A different mounting base is required for the smaller barrel.

Technical Information
Barrel
The 6.978-inch long barrel meets A.I.A. specifications, and is hardened and ground to assure good stability and accuracy.
The outside diameter is 1.7494 to 1.7497 inches.

Auto-Reflection Target
This paired line target is concentric to the line of sight within ±0.001 of an inch. Three spacings exist (0.012, 0.036 and 0.110 of an inch) between the paired lines for use at all distances up to 100 feet. (A 0.092-inch radius circle target is also included.) The target is illuminated from the rear by an auto-collimation light source.

Mounting
The model 381 may be set up using mounting base model 388, 88-6 or "vee" blocks. Custom mounting hardware available by request. (Mounting not furnished with instrument.)

Lighting
Illumination is supplied by a low-voltage lamp to decrease heat distortion and shock damage. A transformer and cord are supplied to step down 110 volt/60 Hz power.

Case
Hardwood case.
