Collimators, testing telescopes and autocollimators from Möller-Wedel Optical GmbH have established an excellent worldwide reputation with scientific institutes and leading manufacturers in the mechanical and plant engineering as well as in the optical industry for decades. This reputation is based on the high quality of these devices with an almost unlimited service life and the modular principle developed by Möller-Wedel Optical GmbH.

A testing telescope produces a magnified image of a distant object. Usually, the adjustment is made to infinity at the wavelength 546 nm, but adjustments to finite distances or other wavelengths are also common and possible. Test telescopes are used in conjunction with collimators for angle measurement and angle adjustment.

Möller-Wedel Optical offers testing telescopes with a straight viewing and with different focal lengths and diameters.
