The utility model discloses a hoist is used in test of optical glass refracting index homogeneity aims at solving the optical glass sample raised the test position difficulty at the hoist problem. Hoist is used in test of optical glass refracting index homogeneity, including sample platform, jib and gyro wheel, jib and gyro wheel all set up at the sample bench, and the upper surface of upward reason than sample platform of gyro wheel is high. This hoist simple structure, make things convenient for the optical glass sample place with the adjustment of test position. During the test of refracting index homogeneity, the gyro wheel that exceeds the upper surface of sample platform through last reason can conveniently carry out the adjustment of test position to the optical glass sample at the sample bench, has improved efficiency of software testing. To anomalous optical glass sample, very convenient just can be balanced with its adjustment, avoid the sample to rock, has reduced the sample and has dropped the acc
