I have an Eprad 47000 series lamphouse with no heat reflecting glass .... Are there special requirements for this glass? What do I need to get?

Last time I ran an old Eprad lamp was years ago. Is yours equipped with a cold mirror or a hot mirror? If it is a cold mirror, you probably don't need one, unless it is a distance corrector. If it is a hot mirror, it'll probably have to be a dichloric filter. Those get mighty expensive.....if they are available for that lamp.

That serries of lamphouse is only a hot mirror
You can get heat filter glass in larger squares and cut them down
Edmund Scientific used to sell it
