Products
Visual Optical Instruments

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.
Diopter Telescopes

Diopter telescopes are adjustable focus telescopes that serve the measurement of optical power of lenses in diopter. The measuring result can be directly read from the diopter graduation.

Double Adjustment Telescope

The double adjustment telescope is a device for testing and adjusting prismatic glasses.

Focusable Reading Telescopes

Our reading telescopes are used for the magnified display of distant objects, e.g. difficult-to-access displays

Square Body Instruments

Our square telescopes and collimators are used on flat reference surfaces to align supporting surfaces to the optical axis.

Software LiveViewer

The LiveVIEWER software enables the intermediate image of the eyepiece reticle plane to be conveniently viewed on a screen and screenshots to be saved for the visual testing telescopes, autocollimators and alignment systems in combination with the Live Image Kit or a C-mount adapter and an industrial camera. The software always works in full screen mode.

Electronic Autocollimators

Autocollimators are optical measuring instruments that can measure the smallest changes in the angular position of optical reflectors. In electronic autocollimators, the autocollimation image is detected by means of CCD lines or a matrix sensor. Electronic autocollimators are primarily used for the following measuring tasks: small angle measurement, ultra-precise angle adjustment and calibration, quality assurance of machine tools and their components, assembly automation, angular position monitoring.

ELCOMAT® direct N Product Line

Each ELCOMAT® direct N consists of the autocollimation sensor and the software ELCOdirect. ELCOdirect can be used with Microsoft® Windows and a current PC, laptop or notebook. The autocollimation sensor is connected to the computer via the USB interface. A Microsoft® Windows Dynamic Link Library (DLL), autocollimation function, is included with the software ELCOdirect.

ELCOMAT® vario N

With the direct signal digitization in the sensor head, the high user-friendliness and extended functions of the display unit 5000 the ELCOMAT® vario N sets a new standard in the ELCOMAT® product line. Like its predecessor ELCOMAT® vario D, the low-cost ELCOMAT® vario N autocollimation sensors can be supplied with a wide range of objective tubes. This variety allows you to choose the most suitable ELCOMAT® vario N for your specific measuring task.

ELCOMAT® 5000

In direct comparison to its predecessor ELCOMAT® 3000, the ELCOMAT® 5000 features a 10-fold higher measuring frequency in addition to a larger measuring range and a better signal-to-noise ratio due to direct signal processing in the measuring head. In addition, internal position sensors can be used for fast and precise alignment of the measuring head and on-the-fly straightness measurement in interaction with the new 5000 display unit.

ELCOMAT® HR

The ELCOMAT® HR is a measuring instrument for applications with the highest demands on accuracy. Ultrastable mechano-optical design and specially developed evaluation and calibration algorithms are the basis for the excellent accuracy. This makes the ELCOMAT® HR ideally suited as a reference instrument for national calibration institutes.

Software for ELCOMAT® vario N, 3000 and 5000

For the ELCOMAT® product series we offer additional software for a number of typical measuring tasks.

Software ELCOdirect

The ELCOdirect software is already included in the scope of delivery of the ELCOMAT® direct product line. The software can automatically and simultaneously detect up to 10 cross positions and automatically determine the wedge angle or the 90° angle error of 90° prisms. Note: Executable under Windows® / The software is not suitable for the ELCOMAT® product line!

Goniometers

The high-precision goniometers of the GONIOMAT product series are indispensable measuring instruments in optics manufacturing and quality control. They enable the angular measurement and inspection of optical prisms, polygon mirrors, wedge plates and angle measures with a measuring accuracy of up to 0.4 angular seconds. An overview of the technical data of all available models can be found here

GONIOMAT A PLUS

The fully automatic goniometer GONIOMAT APLUS is the perfect measuring instrument for measuring and testing of angles, optical prisms, polygon mirrors, wedges and angle gauge blocks. The thoughtful mechanic-optical design and the innovative hard- and software guarantee the high reliability of measurement results and an excellent accuracy of 0.4 arcsecond.

Goniomat A5

The GONIOMAT A5 does not require compressed air to achieve a measurement accuracy of 1.0 arc seconds. The user-friendly control is done by the proven GONIOMATIK Software. It is the cost-effective alternative to the fully automatic GONIOMAT APlus.

GONIOMAT M5 / M5 XL

The GONIOMAT M series, with its combination of manually rotatable precision rotary table and software-supported evaluation of the angle encoder signals in relation to the autocollimation image, enables easy handling with frequently changing test specimen types and, at the same time, low measurement uncertainty. The goniometers are ideally suited for in-process production monitoring as well as incoming and outgoing inspection.

Extension for Ground Prisms

The auxiliary device for the GONIOMAT for angle measurement of prisms with fine ground surfaces. It consists of a collimator f=100 D40 and a deflection system for subsequent mounting on the granite plate of an existing GONIOMAT M5, M 10 or A5. The extension enables the measurement of ground prisms (roughness Rq = 1 .0 µm or less) with a maximum measurement uncertainty of 10 arc seconds.

GONIOMATIK Software

The software is part of the GONIOMAT M and GONIOMAT A product series. It is characterized by a simple and sophisticated user interface and is executable under WINDOWS®10. The software enables standard-compliant evaluation of measurements (ISO 10110-1, VDI 2605 as well as DIN 3140) and offers comprehensive protocol functions. Further components of the software are tolerance specifications and checks as well as an innovative beam calculation based on ray-tracing.

Interferometers

Interferometers are essential measurement tools for the production and quality control of optical components and systems. Their applications range from testing the flatness and sphericity of surfaces to measuring radii and testing the performance of optical systems.
- Interferometer VI-direct 28 SUL
- Interferometer VI-direct 50 PUL
INTOMATIK-S

The INTOMATIK-S software uses the static fringe evaluation method for calculating the surface shape deviation and is thus almost free of influences due to air turbulence or vibrations. However, the fringe evaluation does not achieve the same accuracy as the phase shift algorithm of the INTOMATIK-N software and also cannot automatically determine the sign of the surface shape deviation.

INTOMATIK-N

Due to the phase shifting algorithm the software INTOMATIK-N offers higher accuracy and a larger measuring range with respect to surface form deviations in comparison to the INTOMATIK-S. Additionally the sign of the surface form deviation is automatically determined.

Optical Testing Instruments

In addition to the modular test telescopes, collimators and autocollimators, we offer a range of other visual devices for a variety of measuring and testing tasks in the optical workshop.
Secondary Image Angle Measuring Device (SIAM)

The SIAM is a measuring device for determining the angle between the primary and secondary image on windscreens in accordance with ECE regulation ECE R43. The device consists of an eye-safe laser beam source (laser safety class 2), a testing telescope and the evaluation software. Due to the optical arrangement the measurement is independent of the distance between light source, windshield and testing telescope. The included software allows the automatic determination of the angle as well as the recording of the angle together with the corresponding measuring position on the windshield in a protocol.
