Key Features
Outstanding absolute accuracy achieved in a single measurement.
Benefit: Saves time as no multiple measurements are required.
High precision electronic autocollimator with large measuring range and optimized light intensity combined with a high resolution camera.
Benefit: Facilitates operation and allows the measurement of a large variety of samples including microprisms with a minimum sample size of 1.5 mm².
Software-automated sample tilt compensation (emulated tilt table).
Benefit: Quick and precise measurement of prism angles and pyramidal errors without laborious adjustments.
Stable granite frame for all measuring parts.
Benefit: Utmost mechanical and thermal stability guarantee highest measurement accuracy and repeatability.
Transmission measurements and refractive index calculations performed by the software.
Benefit: No additional equipment - thus easy to operate and time-saving as no modification required
Ultra-stable and accurate rotary air bearing with axial/radial run-out of less than 50 nm and high performance angular encoder.
Benefit: Highest measurement accuracy.
Compact design with full system integration and single-cable connection.
Benefit: Easy to install and to transport.
Measurement table in three different heights.
Benefit: Easy to adapt to different sample diameters and heights.
