SpectroMaster® 600 HR
Automated Precision-Goniometer-Spectrometer
The SpectroMaster® 600 HR is the most accurate refractive index measurement system currently on the market. This accuracy is the result of ultra-high precision components like the motorized air bearing rotary table or the high-class mirror optics and the high-quality manufacturing including careful inspection of all relevant parameters. The motorized goniometer is equipped with backlash-free piezo motors of negligible power dissipation for optimum thermal stability.
- Highest accuracy of 2×10⁻⁶ in the determination of the refractive index
- Maximum wavelength range of 195 nm to 12,000 nm
- Fully automated measurement procedure
More information
- Motorized filter and spectral lamp changer wheel
- Motorized goniometer
- Motorized sample table
- Collimator and autocollimator based on mirror optics. No refocusing over the entire spectral range necessary
- Equipped as standard with Hg and Cd spectral lamps
- Further spectral lamps optionally available
- Equipped as standard with CCD for measurement in the spectral range 365 nm – 1,014 nm
- Further detectors available to extend the measurable spectral range between 195 nm – 2,325 nm
- Infrared light sources between 4,000 nm – 12,000 nm and infrared detectors optionally available
SpectroMaster® 600 MAN
Manual precision Goniometer-Spectrometer
The SpectroMaster® 600 MAN works with mirror optics and thus retains the advantage that the collimator and autocollimator do not have to be refocused over the entire measurable spectral range. The lamp change wheel, goniometer and sample table can be operated manually and the user is guided through the measurement procedure with software support. The measurement system achieves excellent accuracy in refractive index measurement and is therefore an alternative to the fully automated SpectroMaster® 600 HR with lower requirements in the measurable spectral range and measurement speed.

SpectroMaster® 300 MAN
Manual precision Goniometer-Spectrometer
The SpectroMaster® 300 MAN uses refractive optics. The high accuracy of this instrument is achieved by special focusing optics, so that the telescope and the collimator are focused to best collimation at the specific measurement wavelength. It offers a very high system accuracy for refractive index measurement.
- Accuracy of 5×10⁻⁶ in the determination of the refractive index
- Maximum wavelength range from 365 nm to 1,014 nm

Software
SpectroMaster® Software
The complete functionality of the SpectroMaster® instrument is controlled by an integrated Windows 10 based software program.It processes the measured values from autocollimator and high-precision angle encoder to an exact measured value for the refractive index.
With the motorized SpectroMaster® 600 HR, measurements can be performed fully automatically over the complete spectral range. If an approximation for the refractive index of a certain glass type is known, the software searches and automatically measures each programmed spectral line and gives a report on the measured refractive indices. The initial approximation for the refractive index can either be entered manually by the user or calculated by the software via an integrated glass database from stored dispersion coefficients. 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, humidity and pressure.
More information
For measurements with scanning photo detectors which are used in the UV and IR spectral range, the spectral line profiles are scanned automatically and with high resolution, so that the line center position is determined with highest precision. Full motorization ensures maximum independence from the skill of the operator. However, it has been proven that the manual models SpectroMaster® 600 MAN and SpectroMaster® 300 MAN could reach similarly 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 text data output format is available, too.
