Automatic goniometer GONIOMAT APLUS series

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. The GONIOMAT APlus distinguishes itself from conventional goniometers by the following features: • Time saving by using a "virtual tilting table" • Integrated optical ray-tracing analysis of the measurement data Autonomous and reliable image separation in case of multiple reflected images • Precision bearings with backlash-free and maintenance-free drive and angle encoder • No compressed air necessary • High-precision electronic autocollimator with large measuring range and digital camera • Three-dimensional acquisition and calculation of the autocollimation images • Integrated laser finder for easy finding of smallest test specimen surfaces • Integrated measurement cell • Connection of the complete system via a single USB cable Measuring Process • The operator places the specimen on the measurement table • The operator selects the type of specimen (prism, polygon, etc.) through the software menu • The operator starts the automatic measurement process • The software acquires all surface positions by rotating the measurement table automatically • The software reconstructs the prism's geometry utilizing an optical raytracing analysis on the measurement data • The software outputs the surface angles
