PrismMaster® 300 - Precision Goniometer
The TRIOPTICS PrismMaster® 300 is a high precision and versatile automatic goniometer for angular measurements of prisms, polygons and wedges.
The new PrismMaster® series boasts a number of new features including new user-friendly software packed with many new functions. The overall concept of the new PrismMaster® series follows a simple philosophy: providing an instrument with unrivalled accuracy which is also easy to use.
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.
Applications:
- Angle measurements of polygons, prisms and wedges
- Surface tilt errors of prism and polygons
- Wedge errors, parallelism of optical windows
- Deflection angle measured in transmission
- Index of refraction of optical glasses
- Angles of microprisms
- Pyramidal errors
- Angular gauge block
Measuring Process of a Standard Sample
There is no easier way of achieving an immediate and ultra-accurate angle value of plano-optic components. The new software provides fully automated measurement of standard prisms and polygons:
- Prism Configurator for the easy definition of non-standard and compound prisms
- Automated ray tracing for:
- reconstruction of the sample geometry
- classification and selection of the detected images, incl. automatic detection of internal reflections, e.g. in 90° prisms
- refractive index calculation
- virtual transmission measurement of deflection angles
- Input of tolerance ranges and pass/fail classifications
- Evaluation, display and recording of the measurement results according to ISO
