Automatic Laser Goniometer
G-03L
Automatic Goniometer G-03L is designed for precise (automatic) measurements of optical polygon and prism angles.
One measurement is considered as a measurement taken during 16 revolutions of the rotary table (approx. 30 sec of time).
Optical polygon/prism faces can be coated or not coated with reflection layer.
Automatic Goniometer G-03L based on ring laser - new generation of fast digital angle-measurement systems.
Automatic Goniometer provides high precision angle measurement during short time interval.
Continuous rotation of the rotary table with the specimen provides fully automatic measurement with great efficiency. Automatic Goniometer G-03L has different modifications for:
- high precision measurements and certification of optical polygons and prisms manufactured of glass, glass ceramics and metal;
- optical encoder calibration;
- refraction index measurements of different materials by measuring minimum beam deviation angles;
- non-contact measurement of object angular position movements.
Application
- metrology and measuring technique
high precision measurements and certification of angular sensors (optical encoders, regular/irregular polygons, inductosines, etc.) - precision engineering
calibration of rotary tables and test beds, measurement of tool way linearity and flatness of calibration plates - scientific research
determination of angular position of mirrors, crystals and other elements of experimental hardware - navigation technique
