Abstract

The ultra-efficient standard light baffle plays an important role in the calibration of the stray light test system. In this paper, a three-class baffle is designed. And a design scheme of the baffle with honeycombed wall is proposed, by analyzing the stray light transmission model and suppression mechanism, which can meet the requirements of a baffle with ultra-efficient stray light suppression capability. A simulation model of the baffle was established. The simulation of baffle show that when the stray light suppression angle is greater than 8°, the PST value of the baffle reaches 10^-6 magnitude. When the stray light suppression angle is greater than 17°, the PST value of the baffle reaches 10^-12 magnitude, which can meet the needs of ultra-efficient calibration of laboratory stray light test systems.
