INTRODUCTION COLLIMATORS TESTING TELESCOPES AUTOCOLLIMATORS Collimators, testing telescopes, autocollimators and alignment systems are indispensable for the optical workshop. Principal field of applications stretches apart from measurement of angles, quality test of optical systems up to measurement of optical surfaces radii. MÖLLER-WEDEL OPTICAL collimators, telescopes and autocollimators are internationally recognised at scientific institutes and leading manufactures of mechanical and optical engineering. This success story is based on the high quality standards and on a well engineered...

INTRODUCTION COLLIMATORS Alignment systems Alignment telescopes are precision instruments for the alignment of objects on a reference line, which is defined by the line of sight of the system. This property makes them an indispensable tool for the alignment of bore holes and bearings. Beside alignment telescopes we offer alignment collimators and autocollimators. The alignment autocollimator offers the additional possibility of measuring the tilt angle of the target with respect to the reference axis. TESTING TELESCOPES Modules Because MÖLLER-WEDEL OPTICAL equipment is based on a modular...

INTRODUCTION COLLIMATORS TESTING TELESCOPES AUTOCOLLIMATORS Introduction Layout and principle of operation A collimator projects a reticle to a certain distance. Usually the image is at infinity at a wavelength of 546 nm. The main components of a collimator are: ■ ■ Calculation of the angles The angles (α x and α y) of the parallel beam of a collimator adjusted to infinity in respect to its optical axes can be calculated as follows: objective tube with objective reticle sleeve with reticle, condenser and illumination The following figure shows the principle set-up of a collimator adjusted...

TESTING TELESCOPES ACCESSORIES OTHER INSTRUMENTS ALIGNMENT SYSTEMS Fixed or variable distance setting? Fixed, infinity focus collimators are generally the best choice when testing systems adjusted to infinity. Fixed focus tubes set at other than infinity can be ordered. Measuring tasks requiring different wavelengths of light, or measurements requiring focus other than infinity are best accomplished using focusable collimators. [Bild Fokussierbare Fernrohre] a) Small or large objective aperture? Light conditions are more favourable when large apertures are used, and the evaluation of the...

INTRODUCTION COLLIMATORS TESTING TELESCOPES Description: For a general description of the operating principle of collimators see page 6. Notes on ordering: ■ One reticle, 6V/5W illumination w/cord are included in the delivery. ■ If not specified otherwise, the collimator is adjusted to infinity at 546 nm wavelength. Adjustment to other distances or wavelengths is also possible on demand. ■ The nomenclature of the collimators is as follows: K 50/ 40 Example: Objective Illumination Condensor Collimator Focal length Tube diameter Application examples: ■ Measurement of angular displacements (in...

INTRODUCTION COLLIMATORS WITH DOUBLE MICROMETER Description: For a general description of the operating principle of collimators see page 6. A collimator with double micrometer allows the setting of defined image angles in two directions. The movement of the reticle in x- and y-direction in the focal plane is measured with measuring drums. The scale division (SD) is 5 µm. Collimator Focal length Tube diameter Double micrometer Important: Please specify the reticle (see page 82) and illumination (LED-, bulb- or cold light, see page 81) when ordering. Notes on ordering: ■ One reticle and...
