Am I right about:

Pyrex - glass
Lexen - plastic
Borofloat - glass
UCL - glass

Nope,

Lexan - plastic

Not sure what Lexen is? /ubbthreads/images/graemlins/grin.gif

Lexan is also the registered trademark for GE brand polycarbonate resins. Most of what's out in the flashlight lens world is just generic polycarbonate.

Pyrex is a clear pyroceramic.

Borofloat is borosilicate glass, an inexpensive lab glassware grade.

Lexan is polycarbonate

UCL? Don't know what the glass is.
