This paper studies environment correction algorithm in the minimum deviation angle method for refractive index measuring.The principle formula of minimum deviation angle method,based on the refractive index of air and the absolute refractive index of glass specimens is derived.The environmental factors are analyzed which may affect the measurement results in the process of actual measurement.According to thermal characteristics equations of glass,absolute index of refraction of glass for certain material is related to temperature.According to the Edlens equations,refractive index of air is related to temperature,pressure,humidity and so on.Sometimes,the environmental factors is uncontrollable,refractive index will change over the environmental factors,including temperature,pressure and humidity.
