Abstract
The Moller-Wedel Goniometer-Spectrometer Model 1 is a high accuracy instrument for the determination of prism angles and index of refraction in the visible wavelength range (400-700nm). The instrument is capable of absolute accuracy to ± 0.2 arcsec for prism angle measurements, and ±1X10-6 for index of refraction measurements. Recently, we have developed a modified version of this instrument to provide absolute index of refraction measurements in the Near Infrared (NIR) wavelength range (800-2400 nm). The absolute accuracy for index of refraction measurements in the NIR is ±1X10-6.
