@Ozymandyus 500C? more like 1000. and no, its not that bad. it takes a long time for the other end to get hot when it's that long and thin.

Is it strange to anyone else that someone is using a bare hand and metal tongs to hold a supposedly 500 degree penny?

what is groove pitch of this lens?
i bought 0.7m² fresnel lens from ebay, but it has too small groove pitch, so diameter of spot is big because of difraction.

You can snag them from old rear-projection TV's, it's the screen.
