In someway I'm a CRT purist when it comes to coin op arcade games (and old consoles as well). However, I have found it very time consuming and expensive to either fix or replace 25 inch CRTs in my arcade cab. I have found a happy medium. I have created a CRT lens and combined it with an LCD screen. Along with running the proper CRT shader it comes extremely close to a real CRT. I made a mold of a 25 inch crt screen and then casted the screen out of epoxy. After sanding and polishing I combined it with an LCD that fit close to the dimension. See pics and video example in the link below.

Nice! Maximum effort!
Curious, why didn't you vacuum form or heat form a piece of acrylic over the mold instead of pouring resin and sanding/polishing?

If I use an acrylic sheet for the screen it wouldn't bend the light as it should, it needs to be a solid lens. It would be like putting a tupperware bowl over the screen, just be a plastic window on the screen and wouldnt look like a CRT should. Now if you meat why didnt I use an acrylic sheet for a mold of the origional CRT then cast an epoxy lens from that... because I wanted to be able to cast multiple lenses, protoypes, back ups, etc. and didn't know how many I could cast using and acrylic mold vs silicon. Silicon I was able to make multiple. I may try the vacuum forming as molds later for different CRT sizes.
