Abstract

As a kind of main homogenizing device, the homogenizing rod is widely used in laser lighting system. ZEMAX software is used to simulate the light path when the length, tilt degree and aperture size of the homogenizing rod change, and the uniformity of the light spot is calculated by ZPL language in ZEMAX software. The results show that the longer the rod length is, the better the effect is. When the length reaches a certain value, the uniform effect remains unchanged; when the inclination angle is about 0.75 ° and the aperture size exceeds the light source ratio of about 250%, the effect is better Good, the conclusion provides the basis for the selection of the uniform rod in the laser lighting system.
