Abstract

In the paper, an apparatus for high accurate measurements of transmittance and reflectance of large size optical components will be described. The working wavelengths of apparatus are 1.06 micrometers and 0.53micrometers respectively. It can measure both transmittance and reflectance of optical components simultaneously. And both plane and spherical optical component can be easily tested. The apparatus' measurement precision is less than 0.1 percent. The maximum measured size of components is 450 mm in diameter. The heaviest weight of measured component is about 20 kilograms. In this paper, the method of data processing and the schematic diagram will be presented.
