I teach Sensation & Perception at the college level. I had one of these paddle sets but then lost it a few years ago. I am so glad to have found one again! This is great in class to talk about light.
The selection of filters, polarizers, and grating films is great. I appreciate the diffuser as well. Can't wait to deploy this in demonstrations in class. Just using this with my laptop set to an all-white screen, there are so many ways to explore.
We've been ordering from you for more than a decade and love your products. Thank you for the may ways you share your bounty of filters with us - colors, diffraction, solar viewing - you name it. Glad to work with you all always. Keep up the great work.
Lots of intel here. Great for small groups of children.
