Autocollimators measure small angles with high-precision and have stable performance, greater accuracy with easy accessibility. Wavelength Opto-Electronic offer multiples series of Autocollimator such as Base, Std, Pro and Laser based on the accuracy degree. The Laser series uses a laser source, and the others use a white light source. The Laser series has an additional field for CCD chip positioning for the laser high power property. They are useful for optical aligning, precision angle measuring, straightness, parallelism, squareness and flatness measuring purposes.

Goniometer consists of a high precision air-bearing turntable, high accuracy angle sensor and an autocollimator. It is helpful in the absolute measurement of any dihedral angle from 0° to 180° and any 3-D turn angle from 0° to 360°, the beam bending angle of an optical device and the material refractive index. They are applicable in a high-precision test of a rectangular prism, pentagonal prism, polygonal prism and other optical prisms and all kinds of precision measurement blocks and also used in high-precision optical system debugging and the precise positioning of the space of an optical device.

Measuring Angle: Dihedral angle: 0° – 180° / Arbitrary angle: 0° – 360°
Turntable Diameter: 200mm
AutoCollimator Focal Length: 200mm
AutoCollimator Aperture: 30mm
