请教各位GGJJ，
2hf]XV\ 我想用zemax的非
序列模式
仿真玻璃diffuser的透射及反射场。
50r q} - 我用的是thorlabs ground glass diffuser,技术
参数如下：
n7X3aoVV Material: N-BK7 (Uncoated)Scratch-Dig: 80-50Clear Aperture: >90% DiameterPolished Side Surface Irregularity: <4λGaussian Intensity Profile120, 220, 600, or 1500 grit
Lc*i[J<s 请问是否可以使用zemax的内建散射
模型？如果可以，应该使用哪一种？谢谢！！

p- The scattered ray projection vector has equal probability anywhere on the projected plane
- The scattered intensity varies like cos(qs)
- The scattered intensity is independent of the incident angle

s2]
- The scattering distribution is symmetric in direction cosine space
- s determines the width of the Gaussian distribution on the projected plane
- Maximum value allowed for s is 5 (for s > 5, distribution is nearly Lambertian)
d'^jek h ABg #)=P/N1 BSDF(

- Widely used to model scattering due to random isotropic surface roughness
- Input values for A, B, and g are provided in an ASCII file (in the <data>\ABg_Data\ directory)
- Input value limitations: A >= 0, B >= 1.0E-12 (unless g = 0, then B = 0 is allowed)
