glass reflectors

Recommended Posts

Looking for a pair of 7" diameter  glass reflectors for Rushmore headlights.  Whether the silver mirror is good or nor makes no difference.  Must be crack free.  These are the thick glass reflectors, about 1/2" thick.   Any help is appreciated.Thanks

"Looking for a pair of 7" thick glass reflectors" ........."These are the thick glass reflectors"

 

Does any meaningful light escape these?😉

YA, that grabbed my attention too.

I have been playing with reflective optics for 60 years. In the context of the use these reflectors are being put to, the answer is :  No.

"Meaningful" is a relative term, and I think the curiosity stems from the thickness of the glass. There is always some light loss in any reflective or transmissive optical system. In this case the thickness would not play a part. I am trying to avoid TMI, but I could say that in the case of a backsilvered zero power, (uniform thickness - I assume that is what the subject reflector is), meniscus, thickness variation would only impact the spherochromatism. The good news here is that most of the very minimal light loss in this particular system (reflector and lens), actually ends up somewhere in the illuminated field. I hope this helps.   -   Carl
