AUTOCOLLIMATORS FOCUSABLE – STRAIGHT VI EWING WITH DOUBLE MICROMETER
Additionally, micrometers allow the direct measurement of eyepiece reticle movement. The scale division (SD) of the micrometer drums is 5 µm.
Application areas:
■ Measurement of angular tilt
■ Qualitative testing of the imaging properties of optical elements and systems
■ Measurement of large radii of curvature
■ Infinity adjustment to other wavelengths
■ Adjustment of optical and mechanical systems
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.
■ The nomenclature of the adjustable autocollimators with straight viewing and with double micrometer is as follows:
Important: Please specify collimator reticle and eyepiece reticle as well as illumination when ordering.
