■Summary
The ACT-25B autocollimator is a high-precision measurement device capable of resolution down to a fraction of a second. It has a built-in laser for coarse adjustment, a base with leveling adjustment and bubble level and focus adjustment. High quality CCD detectors are sensitive enough to capture and display even the weakest back reflections.
When using the ACT-25B as an autocollimator, the unit has a horizontal measurement range of 42 minutes. In alignment telescope mode, the field of view is 84 minutes horizontally. The PLX ACT-25B autocollimator has a resolution of 0.01 seconds and a focus range from 30cm to infinity. A unique feature of the ACT-25B is its ability to focus down to 30cm (12 inches) in telescope mode.
This feature allows the measurement of lateral displacements, as opposed to autocollimator mode, which measures angular displacements. The ACT-25B is designed as a complete system, ready for use right out of the box. The software suite can automatically display angular deviations and give the relative positions of multiple targets. Accessories for the ACT-25B include a hollow retroreflector, a lateral transfer hollow retroreflector, a lateral transfer hollow periscope, and a tool cube.
■Machine adjustment
Autocollimators/telescopes can be used to check the accuracy of machine slides. To view the slides, attach a mirror to the machine table. The mirror is facing the direction of travel. The autocollimator is aligned with the mirror and the table is moved either continuously or in discrete steps. If there is an error in table movement, the reticle image will move.
■Optical test
Electronic autocollimators can be used to test a variety of optical components. Some can be measured directly, while others require additional optics.
