Autocollimator
An autocollimator measures very small angles with high precision using optical autocollimation. It provides noncontact, sensitive, stable, and convenient detection of angular deviation, straightness, and flatness for precision manufacturing, optical inspection, industrial metrology, and automation. A source illuminates a reticle;the objective collimates it into a parallel beam directed at the test reflector. Returning light retraces the path through the objective and forms an image on a precision sensor. Small reflector tilts displace the image;precise displacement detection and algorithms convert the shift to angular deviation, enabling subarcsecond measurements.

FlaTester Flatness Measurement Instrument Family FT100 Optical Metrology Shineoptics
Structural Configuration: Inverted Measurement Method: Grazing incidence Light Source: Helium-neon laser (632.8nm)
In modern precision manufacturing, single-line scanners and coordinate measuring machines collect too little data to determine flatness over an entire surface. The FlaTester flatness instrument measures complete part surfaces without contact in seconds, accommodating different sizes and complex shapes. FlaTester has 5nm resolution and 50nm accuracy, enabling rapid, precise measurement of flatness, profile, radius, and other surface parameters across various materials and surface finishes.
