Estimation of the Refractive Index of Monocrystalline Sapphire by Polarization Measurements using the MSV-5000 Series

2 Jul 2015

This application note illustrates how polarization measurements were obtained for a sample of monocrystalline sapphire and used to calculate the dispersion of the refractive index. The MSV-5000 series micro-spectrophotometer is ideal for transmission and reflection measurements of samples as small as 10 μm diameter over a wide wavelength range from the ultraviolet to the near-infrared wavelengths.

V-780 UV-Visible/NIR Spectrophotometer

JASCO (USA)

The V-780 UV-Visible-Near Infrared (UV-Vis/NIR) spectrophotometer features a monochromator with automatically exchanged dual gratings: 1200 lines/mm for the UV/VIS region; 600 lines/mm for the NIR region. A PMT detector is provided for the UV-visible region and a high sensitivity InGaAs photodiode detector is employed for the NIR region. Both gratings and detectors are automatically exchanged within the user selectable 800 to 900 nm range.

Infrared / IR SpectroscopyInfrared (IR) spectroscopy measures the interaction of infrared light with a sample, including transmission, reflectance & absorbance, facilitating the identification of analytes. Equipment used for quantitative analysis includes Fourier-transform infrared (FTIR) spectrometers, infrared cameras, FTIR gas analyzers, as well as attenuated total reflectance (ATR) accessories and pellet or film presses.

The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.

Common methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), and eddy-current testing. NDT is regularly used in forensic engineering, civil engineering, mechanical engineering, electrical engineering, systems engineering, aeronautical engineering, and medicine.Refractive IndexCrystallization
