Motorized goniometer SpectroMaster® HR Universal

automatic

The SpectroMaster® HR Universal Goniometer-Spectrometer 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. Key Features Most accurate refractive index measurement system currently on the market with an accuracy of: UV 195 nm – 365 nm 3x10-6 VIS 365 nm – 1014 nm 2x10-6 SWIR 1014 nm – 2325 nm 5x10-6 Motorized air bearing rotary table with axial and radial run-out errors smaller than 0.05 µm High precision piezo motor drive High measurement speed and high positioning accuracy High performance off-axis parabolic mirrors with surface quality better λ/10 Off-axis mirror collimator and autocollimator with infinity setting Geometric beam splitter design ensures wavelength-independent focusing over the full measurement range of the CCD UV-enhanced coating for best reflectivity over the full spectral range of 195 - 2325 nm Additional photo detectors are included besides the CCD. A cooled PbS-detector is used for the infrared and a photomultiplier for the UV . A motorized filter changer wheel can be equipped with up to 17 narrow bandwidth interference filters for easy selection and identification of the measurement spectral line Set of spectral lamps covering the spectral range from 195 nm up to 2325 nm
