Abstract

Abstract

The same optical product can show different stray light coefficients in different measuring conditions, and it is impossible to compare the different results correctly. According to this situation, the stray light coefficients of several kinds of optical lenses have been experimentally investigated in different measuring conditions, such as sizes of block body, receiving apertures of photoelectric device and mounting the collimating objective or not, and the theoretical analysis and experimental results supply the dependences of stray light coefficients on test conditions. The experimental results indicate that the larger size of the black body, the smaller value of stray light; the larger receiving aperture of photoelectric receiving device, the larger value of stray light; the use of collimating objective will induce new stray lights which increase the value of stray light in experiments, but the increased part can be deducted from the results, as the value can be seen a fixed one.
