TIR lens supplier?

[nzoomed]

Is there any supplier of various sized TIR lenses and optics?
Would love to find something that fits perfectly inside an old incan maglite.

Still cant see anything there, seems most optics listed there are not much more than 30mm diameter.
I need something ~2 inches or 51~53MM diameter

The closest thing i can find is this.
Never heard of silicone optics before.
