Optical tooling
Testing & Calibration Equipment

Testing and calibration equipment in surveying and metrology ensures that high-precision instruments—like Total Stations, Theodolites, and Levels—maintain their accuracy over time. These specialized tools are used to detect and correct errors such as collimation drift, tilt sensor inaccuracy, and optical misalignment.
What we carry
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.
