Sunnyvale, Cal. – The AC201 2-axis high-performance angular displacement Digital Autocollimator System from Equipment Solutions, Inc. is a compact high-precision instrument designed to measure small angular displacements with high sensitivity over distances to 2.0 in. (5.06 cm).
The AC201 Digital Autocollimator is ideal for instrumentation, tooling, and OEM manufacturers with requirements for high precision alignment, flatness, squareness of surfaces in relation to each other, detection of angular movement, shaft straightness, motion control, and other orientation measurements. This rugged and compact 1.0 in. x 1.1 in. x 1.3 in. (2.5 cm x 2.8 cm x 3.3 cm), low-cost digital autocollimator can also interface with a PC.
The AC201 Digital Autocollimator has an optical angular range of ±344 arc sec (±100 mrad), and a sensitivity of 0.2 arc sec (1.0 µrad). The laser has a beam diameter of < 0.125 in. (<3 mm) and requiring only a slightly larger reflection surface. Electrical requirements are: +5.0 VDC @ 30 mA. It can be factory configured with one of several different interfaces including analog, USB, SPI, or quadrature encoder. The black anodized (per MIL-A-8625C) 6061-T6 Aluminum body has 2x 4-40 mounting holes and integral electronics and connections are via a Nano D9 or USB connector.
Supplied with a Windows® application software and more than 24 ASCII commands for control and operation, the AC201 Digital Autocollimators can perform complex data collection and analysis. They are ideal for vibration analysis, mechanical and optical alignments, servo control feedback, tip & tilt 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, and medical analytical devices.
