Paper Abstract

It is difficult to measure the transmittance of large aperture optical lens, when incident beam runs in a wide angular range and in a scanning way, especially of those with different apertures in the same setup. Here an automatic spectrometer setup has been built, which can measure the transmittance of various large aperture optical lens in the visible spectrum. It is composed of a coordinated four-axis mechanical system, sample fixtures and an advanced optical system. It can give one-dimensional scanning result of samples with varied surface apertures in a wide range of incident angle, as well as at a fixed point. The incident angle of the testing beam is allowed to range from -80° to 80° . Moreover, various measurement errors and corresponding solutions were discussed in this paper. It has been proved that this spectrometer setup can give results accurately.
