This paper describes measuring principle of the photo electric automatic refractometer with high precision in the wavelength range 365 to 12000nm and its constraction and discusses the sources of error.The refractive indices of different optical materials are measured with this instrument.The measuring uncertainies of better than 3?10
-6
and 3?10
-5
in the wavelength range of 365 to 2600 nm and 2600 to 12000 nm are obtained
