SpectroMaster® HR Compact - High Precision Manual Goniometer-Spectrometer
The SpectroMaster® HR Compact Goniometer-Spectrometer uses refractive optics and is therefore limited to the visible spectral range from 365nm to 1014 nm.
The high accuracy of this instrument is achieved by special focusing optics, so that the telescope and the collimator can be focused to best collimation at the specific measurement wavelength.
The manual SpectroMaster® HR Compact employs a differential micrometer screw for the greatest sensitivity and accuracy during the manual adjustment of the telescope angle. Due to the sophisticated software assistance and alignment indicators, it has been proven that manual operators can reach the same high accuracy of the motorized version but at the cost of reduced measurement speed.
Key Features:
- System accuracy for refractive index measurement:
5×10-6 (sample size at least 10 mm) - System accuracy for angle measurement:
±0.5 arc sec - Manual air bearing rotary table with axial and radial run-out errors smaller than 0.05 µm
Focusable collimator and focusable autocollimator for a wide spectral range
HgCd spectral lamp with spectral lines
between 404.6 nm and 643.8 nm as standard and optionally between 365 and 1014 nm - Spectral lamp covering the spectral range from 365 nm up to 1014 nm
Applications:
SpectroMaster® Goniometer-Spectrometers are used for high-precision determination of the refractive index and dispersion of optical glass and crystalline materials in the UV, VIS or IR spectral range.
SpectroMaster® HR Compact - Software
The complete functionality of the SpectroMaster® instrument is controlled by an integrated Windows 7 based software program. It employs CCD camera and photo detector readout, including the full configuration of attached amplifiers and controllers. With the motorized SpectroMaster® model, measurements can be performed fully automatically over the complete spectral range of the chosen detector and spectral lamp. When the approximate refractive index is known for a certain glass type, the software searches and automatically measures each programmed spectral line and gives a report on the actual index values with the highest accuracy. Additionally, sophisticated tools enable the quick and easy characterization of unknown glass types, so that accurate refractive index data can be obtained in a few minutes. Of course, the software corrects the measurement data to take into account the ambient air refractive index depending on temperature and pressure.
In CCD camera measurements the software relies on the approved image analysis algorithms of TRIOPTICS PrismMaster® and OptiAngle® instruments for the accurate detection of spectral line positions. In scanning photo detector measurements, the spectral line profiles are automatically scanned and the line center position is determined with the highest precision. Full motorization ensures maximum independence from the skill of the operator and makes repeatability in the range of 10-7 possible. However, it has been proven that the manual models could reach the same high system accuracy due to precise alignment indicators assisting the operator in gaining maximum accuracy.
Of course, the software generates a complete and detailed measurement certificate. For further analysis, a RAW data output format is available, too.
