“…For the optical system applied in different environments, the shape and size of the shading tube of the baffle will also change accordingly. According to the volume of the system and the shading effect to be achieved, the shading type of reflection, shading or both is designed according to the attenuation of stray light such as reflection and absorption [17][18][19][20] . At present, the shape of the shading cylinder is generally designed to be cylindrical or conical, as shown in Figure 2.…”

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.
