Vacuum ultraviolet spectrometer McPherson VUVAS 1000
The VUV spectrometer allows you to measure reflectance, transmittance and scattering of light in the vacuum ultraviolet spectral range. It allows you to extend optical characterization into areas that are inaccessible to conventional optical instruments. Conventional optical instruments are mostly limited to a wavelength of 190 nm (6.5 eV), which corresponds to the transmittance of fused silica optical elements and the transmittance of the atmosphere.
Specification
- Single-channel vacuum spectrophotometer: 115-320 nm (3.88-10.78 eV)
- Transmittance, reflectance or scattering measurement
- Detector on goniometer: 10°-180°
- Working pressure: 10-3 Pa
- Various sample holders: standard 1 inch
