Low Cost Auto Collimator with 0.5 µrad Sensitivity Performs Complex Data Collection and Analysis



Sunnyvale, CA, - The AC421 2 axis angular displacement Autocollimator System from Equipment Solutions, Inc. is a high precision instrument designed to measure very small angular displacements with high sensitivity over distances to 78.7 in. (200.0 cm). Highly portable, the compact 12.3 in. x 2.5 in. x 3.2 in. (31.2 cm x5.1 cm x 8.1 cm), low cost autocollimator can interface with a PC, or handheld color touchscreen interface. For unparalleled accuracy in the laboratory and on the factory floor a DSP signal processor and temperature-controlled lasers and sensors compensate for environmental disturbances.

The AC421 Autocollimator has an optical angular range of ±2160 arcsec (±10mrad), and a sensitivity of 0.1 arcsec (0.5 µrad). The standard 670 nanometer red laser has a beam diameter of <3mm typical (a green laser is optional). Other options include: Stand/mounting base, reference mirrors, USB interface (an RS-232 computer interface is standard), and translation displacement sensor. Additional features of the series include: Visible laser pointer function, wide scanning angle, low noise, and large aperture.

Supplied with a Windows® application software and more than 24 ASCII commands for control and operation, the AC421 autocollimators are able to perform complex data collection and analysis. They are ideal for: Vibration analysis, mechanical and optical alignments, servo control feedback, pitch & yaw measurements, settling time and stage damping analysis, and measurements needed in the manufacturing and testing of miniature mirrors and lenses, linear and rotary stages, fiber optic components, robotic components, silicon components, and medical analytical devices.
