Autocollimator
An Autocollimator is a high-precision optical angle measurement instrument designed for detecting extremely small angular deviations. Based on the optical autocollimation principle, it enables accurate measurement of angular displacement, straightness, flatness, and other geometric parameters.
With advantages such as non-contact measurement, high sensitivity, and easy operation, autocollimators are widely used in precision manufacturing, optical component inspection, industrial metrology, and automated measurement systems.

Product Advantages
-
High-Precision Detection with Sub-Arcsecond Resolution
A precision CMOS sensor enables highly accurate photoelectric detection, achieving sub-arcsecond resolution for high-precision angular measurements.
-
Wide Field of View for Larger Deviation Range
With a field of view up to ±0.9°, the system measures larger angular deviations and improves measurement adaptability.
-
Non-contact Measurement with Long-Distance Positioning
An integrated laser coarse positioning module enables non-contact measurement and fast positioning of distant target surfaces.
-
Fast Response for Real-time Angle Tracking
High-speed sampling and rapid response capture angular variations in real time, improving dynamic measurement efficiency.
