Digital Photoelectric Autocollimator

The Digital Photoelectric Autocollimator is a high-precision non-contact optical instrument designed for measuring extremely small angular deviations. Combining the principles of a collimator and telescope, the system projects a collimated beam onto a reflective surface and analyzes the returned image to determine two-axis angular displacement with high accuracy.

Equipped with an industrial-grade CCD camera and sub-pixel image processing technology, the system provides real-time optical image display and stable recognition of multiple target patterns. It is widely used in precision mechanics, optical alignment, guideway inspection, rotary stage calibration, and laboratory measurement applications.
