AUTOCOLLIMATORS 90°-VI EWING
An autocollimator with right angle viewing has the user’s line of sight at 90° to the objective axis. These autocollimators are preferably used down-looking and on optical tables where a straight viewing is not feasible.
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 90°-viewing is as follows:
Important: Please specify collimator reticle and eyepiece reticle as well as illumination when ordering. Please specify direction of use if reticles with lettering are used so that the lettering will be right-side-up.
