The Development of the Glan-Taylor Prism AR Film
Glan-Taylor棱镜端面增透膜的研制

For increasing the transmissivity of the Glan-Taylor prism and making it's performance better,the design,evaporation and measurement of the Glan-Taylor prism's antireflection films were studied. The suitable film materials and control condition were found by engneering testing for many times and solved the problem of the adhensive power between the film and the iceland crystal. The film structrue was designed using the film soft and the film was evaporated the film on the iceland crystal surface according to the film structrue which had been designed. The reflective spectral of the antireflective film were measured by spectral photometers. The result of the measurement shows that the reflectance of the end surface,which had been filmed,is less than 0.4% in the rang of spectral regions,and the adhesive power of the film is firm.
