6D autocollimator - Darkfield model is perfect for measuring small, flat mirrors.

nikon metrology autocollimators 6B 6DNikon's 6B autocollimator checks alignment and measures very small angular deviations to measure flatness or height by simple geometry. The 6D darkfield model projects a bright crossline and is the most popular model because the bright-line cross is the easiest to see. 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 6D employs a 70 mm aperture lens to product clear, reflected images. It also features extremely accurate double line reticles for improved detection.


Viewfield diagram

The 6D Autocollimator makes high-precision measurements simultaneously on two axes with the darkfield technique. It projects a bright crossline and Nikon's most popular model because the bright-line cross is the easiest to see.
