Whats up fellas,
Nearly done with my PJ, but I just cant seem to find a proper IR filter for it so my LCD picture starts getting a little dark with the heat. As far as I can tell either I have to put a whole bunch of those tiny IR filters together (the ones that are sold on most of the DIY PJ sites), or get some Low-E Glass. Now I have been searching all over the place for someone who will give me a custom cut piece (15" x 10"), but I cant seem to find a source. Has anyone had any luck in the states tracking down a dealer that has no minimum order and will give me a piece in the size that I want? Thanks in advance!
P.S. - a cold mirror has not been incorporated in my design.

I was able to get low-e glass from a local glass shop. (If you haven't already) Check the phone book. I live in a really small town, so I assume you shouldn't have a problem finding some.
Yeah, already tried them, they have a minimum order of 5 square feet 😡 . I guess i will have to try other towns, thanks for the reply though.

from what i hear
Fellas,
Ok i did a little more research on Low-E glass and also found a dealer that is inexpensive in my area. But, from what I have read it seems that Low-E glass only reflects longwave IR (actual heat like off the dashboard of a car). But what im looking for is something to block the shortware IR, so that it doesnt even reach my LCD, become absorbed by it, and cause it to heat up. All low-e glass seems to do is just keep the heat from the bulb in one place, not filter the light that is actually passing through the pane of glass. Can someone correct me if im wrong. Thanks.

Answer #1
Youre right about one thing Low E glass does not block UV. Low E is also very hard to custom make because of the gas inside it. You'd have to cut the special glass then create a small gap then create a rubber around or metal then inject the gas. For DIY Projection Low E is not the way to go in small LCD's but for 17" or larger (wow) its good. What are you trying to block, heat or UV and what is the LCD size?

15" here
Im trying to block shortwave IR heat from getting to my LCD panel. If i could block this heat that is radiated from the light of the bulb my LCD would not absorb it and heat up. BTW, Im using a 15" toshiba panel from a dell monitor. And i have found someone who will make a piece of Low-E glass in the size i want but i dont know if its what i really need, it doesnt seem to filter IR just insulate and form a barrier.
