AI Thread Summary

Photochromic lenses analyzed in a laboratory using a spectrometer have not been matched by various Chinese manufacturers, who instead provided similar materials. The inability to replicate the exact specifications may stem from differences in manufacturing processes or material availability. To resolve this issue, sourcing from German or American manufacturers is recommended, as they may have more advanced technology or better quality control. Additionally, providing detailed specifications and laboratory data could help in achieving a closer match. Exploring alternative manufacturers or technologies may also yield better results.

TL;DR Summary: Photochromic lenses

Hello,

I have a photochromic lenses that I analyzed in a laboratory using a spectrometer. I sent the obtained data to various manufacturers in China, but for some reason, they are unable to produce an exact match. Instead, they sent me a similar material.

What could be the reason for this, and how can I solve this issue?

Thread 'Simple math model for a Particle Image Velocimetry system'

Hello togehter, I am new to this forum and hope this post followed all the guidelines here (I tried to summarized my issue as clean as possible, two pictures are attached). I would appreciate every help: I am doing research on a Particle Image Velocimetry (PIV) system. For this I want to set a simple math model for the system. I hope you can help me out. Regarding this I have 2 main Questions. 1. I am trying to find a math model which is describing what is happening in a simple Particle...

Thread 'How to model converging illumination through object plane (in ZEMAX)'

Hello community, I'm designing a projection lens system for a 35mm film projector in Zemax OpticStudio and struggling with the correct sequential mode setup for the illumination geometry. The light source is a Xenon short-arc lamp reflected by an ellipsoid mirror, which creates a converging cone with a 40.6 degree full angle that passes through the film gate. The film gate is my object plane, but the light doesn't diverge from it like a typical Lambertian source. Instead, the converging...
