Optics Tutorial - 7 - Fnum, windows, FOV

[@opticsrealm]

GRINS are really cool. There are radial GRINs and axial GRINs and I hope to present those some day. I'm trying to release videos in a rational progression. The radial GRINs tend to be small diameter, like the SELFOC lenses. Axial GRINS create an aspheric wavefront but the lens has a spherically polished surface - the material comes from LightPath.

Just getting an overview!

I was disappointed that you didn't actually define FOV in this presentation, despite the title and introduction : /

Same, I've been having trouble finding a good explanation backed with math elsewhere, was really hoping this would shed some light. I was wrong...

What you're doing is really great, but please consider these few remarks. No need to zoom-in on the formulas, slides aren't too crowded for that and it would be more helpful to see the entire slide all the time. Also, a bit weird to have the webcam video covering a part of the slide with useful information. Thank you otherwise, very useful.

i have a sensor with 90 degree FOV. i have a lens of height 12mm and focal length of 50.8 mm. i want my sensor to measure infinity (Fov=0). what would be the calculation?

[@roachsalad]

Awesome keep the videos coming.

[@stepanvyhlidka]

nice videos, thank you

[@MrAMVision]

Very interesting videos, Please, could you make a tutorial about GRIN lenses on ZEMAX THX
