First Surface Mirrors for Rear projection, etc.
We have 4 large First Surface Rear Projection mirrors. We haven't provided any photos of the mirrors themselves, because it would serve no purpose.
4 op voorraad
The glass is .250 inch thick optical grade float glass. This type of glass is used in demanding applications where no image distortion is tolerable. I have 4 mirrors available;
Asking prices for the 40x50 are $399 each and the 60x66 mirrors are $599 each. Accepting any reasonable offer for all 4.

These mirrors sell for thousands new. Most often found in rear projection systems. Also used in jewelry cases. These would be a very unique and possibly scary addition to a beauty salon or barbershop.
This type of Mirror applies the silver to the Front of the glass, thus eliminating the second or Ghost Image that one normally sees with a conventional back silvered mirror.
This from Wikipedia:
A first surface mirror or front surface mirror (also commonly abbreviated FS mirror) is a mirror with the reflective surface being above a backing, as opposed to the conventional, second surface mirror with the reflective surface behind a transparent substrate such as glass or acrylic. In cases where the mirror is subjected to extreme cold (as low as 33 K as in the James Webb Space Telescope), a polished pure beryllium mirror is used without a first surface coating in order to obviate buckling caused by differing coefficients of thermal expansion.
They are made for applications requiring a strict reflection without a ghosting effect as seen with a second surface mirror, where a faint secondary reflection could be observed, coming from the front surface of the glass. This includes most optics applications where light is being manipulated in a specific manner. Telescopes, rear-projection televisions, periscopes, non-reversing mirrors, high quality kaleidoscopes, and the animation process Spectrafocus use this type of mirror.
