    12 to 24 inch diameter parabolic reflector
    Does anyone know where to get a "Deep 12-24 inch parabolic aluminum or steel mirrored reflector" ? Many of the science or lighting labs I find, don't seem to have "deep" dishes, only shallow ones with a small hole in the bottom. I need a bigger hole such as 3 inches or more. Glass is okay, such as from an old traffic light reflector.

    I really don't know.

    Have you tried eBay?
    Or maybe there's a forum somewhere for collectors of old traffic lights?

    What's it for?

    I ground a parabolic mirror out of porthole glass once, but that's not going to help you...

    These guys Oriel Sales use them in their solar simulators. It's a deep parobolic reflector, metalized aluminum, I believe, but they might cost you about a grand.

    I have a 24 inch glass mirror with a short focal length about 18 inches. It weighs about 80 lbs. I could let it go.

    More info 24 inch mirror. It came with a corrector plate, half inch glass. The mirror has about a 3 inch hole in the center, I think it was made for some sort of projector.

    I've been trying to reply to this, Do you still have the 24 inch reflector? I can come by and pick it up.

    I've had some luck building a 24 inch reflector, check out 24 inch LightSward on Candle Power Forum. I had trouble logging on and didn't respond right away.
