AUTOCOLLIMATORS STRAIGHT VI EWING – WITH DIGITAL DOUBLE MICROMETER
An autocollimator with a micrometer driven eyepiece reticle can directly read reticle displacement for higher accuracy compared to a fixed reticle. In place of the micrometer drums above, optionally, programmable digital gauges allow direct reading of the tilting angle in arcsec or milliradians.
Application areas:
■ Measurement of angular tilt
■ Measurement of parallelism of plane plates
Notes on ordering:
■ Optionally, the autocollimators can be equipped with an eyepiece having 10 mm or 25 mm focal length.
■ Two reticles, 6V/5W illumination w/cord, and eyepiece are included.
■ If not specified otherwise, the autocollimator is adjusted to infinity at 546 nm wavelength. Adjustment to other distances or wavelengths is also possible on demand.
■ Specify the unit of display of the digital gauges (mm, arcsec, milliradians).
■ The nomenclature of the autocollimators with straight viewing and digital double micrometer is as follows:
Important: Please specify collimator reticle and eyepiece reticle as well as illumination when ordering.
