BRUN-271 Tilt Collimator

BRUN-271 Tilt Collimator:

Provides (2) reticles -near and infinity- for optical instrument testing and evaluation. Specially mounted spirit level vial is fixed to the barrel to set the collimator’s reticle pattern in a plumb orientation.

Infinity target is graduated for angular measurement estimations, with a resolution of 30 arcseconds and a range of ±30 arc seconds in two directions. Paired-line near target allows offset measurements when using instruments with micrometers.

 

BRUN-27215 Multiple Target Collimator:

Available with multiple targets (shown) or graduated targets (BRUN-272MC).

BRUN-27215 Multiple Target Collimator

Multiple purpose test collimator, specifically designed for use in collimating test stands and instrument adjustment applications. Each adjustable target contains a label identifying its location along the optical path. Allows for testing and calculation of the deviation of any optical instrument’s line of sight from a perfectly straight line.

Specifications:

  • Barrel: Outside diameter of 2.4994” to 2.4997”. Meets A.I.A specifications
  • Length: 14” (BRUN-271) 18” (BRUN-27215)
  • BRUN-271 Targets: Displacement and infinity targets; 0.092” radius circle target also included
  • BRUN-27215 Targets: Filar/Bi-filar pattern with approx. distance settings of 2, 4, 6, 16, 25, 50, 75 ft. as well as infinity
