Trichroic Prism

A dichroic prism splits light into two beams of differing wavelength (colour). A trichroic prism assembly combines two dichroic prisms to split an image into 3 colours. They are usually constructed of one or more glass prisms with dichroic optical coatings that selectively reflect or transmit light depending on the light's wavelength. That is, certain surfaces within the prism act as dichroic filters. These are used as beam splitters in many optical instruments. (Wikipedia)

Tim is such an honest, good soul we need more people like him.

I remember finding one of these in an old projector, it mystified me as a kid.

[Jawaddles]

This is the most calming episode ever. I love it. It really puts one's mind at ease.

Although Tim touches on science, he is all about the whimsy, and that is what makes him so cool!!! His style reminds me of Mr Wizard, a TV show host we had in the US. Many shows fashioned themselves after him but only captured the honesty, imagination, and curiosity that I remember from Mr Wizard! Thank you, Tim.

imagine having one of those on a rotating platform with a light focused on it.
would make a room look pretty magical.

Tim is the Bob Ross of toys. his voice and the way he talks soothes my soul

[adammotala]

Tim: "Wow!
-
Well now that I've got your attention..."

[frysco]

I was feeling really depressed and honestly really shitty today, until I found this account. Watching these videos makes me smile, and they're quite fascinating to watch. I'm feeling much better after having watched a few of these. Keep up the good work, Tim!

[Aurasmae]

This is honestly one of the most beautiful things I have ever seen.

[Mimsyborogove]

Geez, got all super relaxed watching him shine the light at the end and then abruptly awoken by the outro!

[optimisticwhovian]

I often love spraying a hose into the air to make my own rainbow but this is easier, never ceases to amaze me how you can just create these colours seemingly out of thin air.

[franceslovesrainbows]

I absolutely love the opening:
"Wow! ... Now that I've got your attention, "
:')

TIM YOU ABSOLUTE MADMAN UPLOADING TWICE IN ONE DAY

[lordseafood]

Didn’t expect to find something from Tim when searching for glass prism, but this video deserves a like and this channel deserves the highest honor I can bestow: subscribed *all notifications*

[RoySATX]

Oh, I know just how he feels. At fifty-eight years of age I am neither easy to surprise nor easy to amuse, but hand me a trichroic prism and a flashlight and suddenly I'm eight years old again! I've never heard of this man nor seen any of his videos, seeing just this one has convinced me to subscribe. After all, if you must see illusions, and apparently I must, then shouldn't they be grand ones?

[christinavaughan]

I had one of those when I was little! My dad used to work on those old big screen tv's and I think he got it out of one of them, and gave it to me. I played with it all the time, and now I really miss it.

[Bobbydog]

0"05 Oh tim, when it's your vids, you've always got our attention.

[WhiskeyDip]

There's a guy named Jack Storms and he takes an effect similar to this (he uses dichroic aside from trichroic) and turns it into a glass sculpture masterpiece. It takes him months to finish one project as he has to build it layer by layer. Just search him on Youtube. It's amazing

[stupidmovies]

Tim should do vlogs of his travels to toy shows honestly. If he isn't down to filing himself he could do it documentary style, interviewing toy inventors, telling stories, etc.
