The patent pending extension for ground prisms for the GONIOMAT M5/M10 Goniometers allows the measurement of prism angles with a fine grinding / roughness of up to Rq = 1.0 µm and a measurement uncertainty of less than 10 arcsec. The achievable accuracy and measurability of the test specimen depends on its surface size, and…
The GONIOMAT M is a semiautomatic goniometer with robust, innovative, and easy to use software. This instrument is perfect for quickly and easily measuring the geometry of prisms, polygons, wedges, angle gauges, and more. The GONIOMAT M series comes in two levels of accuracy:
GONIOMAT M5: 1.5 arcsec
GONIOMAT M10: 2.5 arcsec
Also available as GONIOMAT M5 XL, for measuring large systems and parts.
The GONIOMAT A uses the same measuring principle and software as the GONIOMAT M, with increased accuracy and an automatic rotary stage. A housing around the instrument provides an environment free of external disturbances to further increase accuracy and repeatability. The GONIOMAT A is also available in two levels of accuracy:
GONIOMAT A5: 1 arcsec
GONIOMAT Aplus: 0.4 arcsec
The Goniometer II can be used for geometry measurement, as well as the precision measurement of refractive indices of transparent media in the UV-VIS-IR from 254nm – 2325nm. Refractive index measurements are accurate to 1 in the 5th decimal place. Liquids can be measured using a special hollow prism.
While the Goniometer II is outdated by the GONIOMAT series, it is still an excellent instrument for certain applications.
