Testing Telescopes with Micrometer Type FG MD & MDD | MÖLLER-WEDEL OPTICAL
MÖLLER-WEDEL OPTICAL GmbH offers testing telescopes with fixed and variable focus settings with straight, 90° and 60° viewing (only with fixed focus setting). Versions with mechanical (MD) or digital double micrometer (MDD) are also available. A testing telescope provides a magnified real image of a distant object. Usually the image is at infinity at a wavelength of 546 nm (Green). But also alignments to 470 nm (Blue) or 660 nm (Red) are possible.
