A high precision VIS/NIR dynamic goniometer-spectrometer
Metrologia. 2023. Vol. 60. No. 4. Article 045007.
We present a method for measuring the refractive index (RI) and spectral characteristics of transparent triangular prisms based on the minimum deviation technique. The proposed method has been developed to automatically measure RI simultaneously for three different wavelengths to determine the spectral dependence of RI. A high precision dynamic goniometer with a He-Ne ring laser and continuously rotating autocollimation mirror was used to implement the proposed method. A set of reference prisms made of optical glass were experimentally studied and the measurement uncertainty budget was estimated. The obtained values of the expanded measurement uncertainty did not exceed 4.6 × 10−6 for near-infrared and 1.2 × 10−5 for visible wavelength ranges with a coverage factor k = 2 (95% level of confidence). It is shown that this method can be used for high-precision measurements of the RI and determine the spectral characteristics.

We present a new autocollimation method for measuring the refractive index (RI) of transparent triangular prisms. The classical autocollimation method is simple, but due to total internal reflection it is suitable only for prisms with small angles, which limits the accuracy of RI measurements. The proposed new method makes possible the autocollimation measurements of the RI for prisms with ...
