AUTOCOLLIMATORS STRAIGHT VIEWING
An autocollimator with straight viewing has the user’s line of sight co-linear with the objective axis. These autocollimators are preferably used in horizontal direction, where the eyepiece is at eye level. In a down-looking arrangement or on optical table 90°- or 60°-viewing is often more suitable.
Application areas:
■ Measurement of angular tilt
■ Measurement of parallelism of plane plates
■ Adjustment of optical elements
■ Qualitative testing of the imaging properties of optical elements and 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.
■ 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.
■ The nomenclature of the autocollimators with straight viewing is as follows:
Important: Please specify collimator reticle and eyepiece reticle as well as illumination when ordering.
