    Grating Reflection
Click For Summary
Reflection gratings function as diffraction sources by altering the angle of the incident light beam, which causes the light to spread into various directions based on wavelength. A steel ruler can be used as a reflection grating due to its finely spaced edges that can diffract light, although it may not be as effective as specialized gratings. The discussion hints at the educational context, suggesting that the questions posed may stem from a homework assignment. Understanding the principles of diffraction and the role of angle in light behavior is crucial for applications in optics. Overall, the mechanics of reflection gratings are essential for manipulating light in various scientific and practical applications.

Can a steel ruler be used as a reflection grating ? if so, why?
 
Why do I get the feeling this is a homework question?

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...
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...
