Möller-Wedel Optical GmbH ® Our ELCOMAT Product Line Autocollimators are optical measuring instruments that measure the smallest changes in the angular position of optical reflectors. They are mainly used for the following measuring tasks: measurement of smallest angles, ultra-precise angle adjustment and angle calibration, quality assurance of machine tools and their components, assembly automation, angular position monitoring. Each ELCOMAT® direct N consists of an autocollimation sensor and the ELCOdirect software, which can be used with Microsoft® Windows and a current PC or laptop. More...

ELCOMAT direct N Electronic Autocollimator ® Autocollimators are optical measuring instruments that measure the smallest changes in the angular position of optical reflectors. In electronic autocollimators, the autocollimation image is detected by CCD lines or a matrix sensor. Δx Position of the reticle image on the matrix sensor before mirror tilting The ELCOMAT® direct N is particularly suitable for the following measuring tasks: n Small angle measurement n Ultra-precise angle adjustment and calibration n Wedge and prism angle measurement n Assembly automation n Angle position monitoring...

Each ELCOMAT®direct N consists of an autocollimation sensor and the ELCOdirect software. ELCOdirect is designed for use under Microsoft® Windows on current PCs or laptops with a USB 3.0 interface. The autocollimation sensor is connected to the computer via the USB interface. A Microsoft® Dynamic Link Library (DLL), which covers the autocollimator functions, is included in the software. Selection criteria Depending on the requirements of your measuring task with regard to measuring range and measurement uncertainty, you can select the suitable ELCOMAT®direct N from the product range with the...

ELCOMAT direct N ® Dimensions of the different ELCOMAT direct N ® The autocollimation sensors of the ELCOMAT® direct N series allow the selection of the most suitable sensor for the application due to the wide range of objective tubes. The ELCOMAT® direct N housing has two connectors: One for connection to the computer and one for connection of a laser attachment for rough alignment of the autocollimator to the reflector.

ELCOMAT direct N Software ELCOdirect ® The ELCOdirect software is included with the ELCOMAT® direct product series. The software can automatically and simultaneously measure up to 10 cross positions and automatically determine the wedge angle or the error of the 90º angle of 90º prisms. Note: Runs under Windows® / The software is only suitable for the ELCOMAT® direct product series! Software Tools The software provides numerous help functions, such as screen zoom and measurement scale display, to facilitate daily measurement tasks. Advanced parameters such as camera area of interest and...

Cartesian or Polar Coordinates The value display can be configured to show angle values, wedge angles, or height differences with respect to a user-defined base length. Values can be displayed in Cartesian or Polar coordinates. Tolerances Go/NoGo tolerances can be displayed for quick and easy evaluation of the measurement result. Centering Mode In the centering mode of the ELCOdirect Software, for example, the centering error of optical components in relation to the common optical axis of the entire system or the wobble error of rotary tables, can be calculated.

ELCOMAT direct N Typical applications ® Typical applications for the ELCOMAT® direct N series are: n n n Wedge angle measurement Angle measurement on 90°-prisms Alignment of optical components Position uncertainty (rotatory) Wobble error Centering Measurement of surface parallelism Wedge Angle Measurement The wedge angle can be measured by either double cross or deflection angle. The first method offers higher accuracy than the second and does not require an additional mirror. A limitation of the method is that it requires a separation of the autocollimation images in the order of the...

Alignment of optical components With the ELCOMAT® direct N product series, the alignment of optical components (e.g. prisms and mirrors) is possible. Due to the possibility of simultaneous evaluation of several autocollimation images, components can even be aligned when autocollimation images of other components appear in the camera image. Wobble Using the centering mode of the ELCOdirect and a plane mirror, the ELCOMAT® direct N can be used to determine the wobble of spindles or rotary tables. Position Uncertainty (Rotary) Determine the position uncertainty of indexing and rotary tables...
