Nikon's 6B autocollimator checks alignment and measures very small angular deviations to measure flatness or height by simple geometry. The 6B brightfield model projects a dark cross and illuminates the surface so you can see details. Provides measuring accuracy down to 0.5 arc seconds.

Key benefits

  • Efficient measurement - the autocollimator needs only the setting of a target mirror and collects reflected light rays
  • Simultaneous measurement of vertical and horizontal axis values

Applications

  • Surface Analysis

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Benefits & features

Half second measuring accuracy

Readings of angular displacement of 0.5 second of arc using an easy-to-read large-diameter micrometer drum.

70 mm aperture lenses

The 6B employs a 70 mm aperture lens to product clear, reflected images. It also features extremely accurate double line reticles for improved detection.
