Modified formula of environmental conditions in precision measurement of optical glass refractive index

The article points out the inadaptation and defects of air pressure correction formula which is used currently in the precision measurement of optical glass refractive index. Based on the latest formula of air refractive index, the article also focuses on the research of environmental conditions and puts forward a new correction formula. And the article indicates that different correction formulas should be used in different testing precisions and different test conditions.
