First surface mirror sources

AFlood · Aug 29, 2009

Hi Folks,
The mirror on my bronica is in a right state, its covered in gunk which seems to come from the deteriating light seals that the mirror flips up onto. In parts it looks like the silvering has been worn away. Does anyone know where I can get either a replacement mirror, or a piece of first surface mirror that I can then cut to shape? Will a polaroid mirror be big enough for a bronica sq?
Cheers,
Alex.

Hi-- you might try Edmund Scientific. They carry some odds and ends in optical supplies.

I would replace the mirror with a new one from Bronica as the thickness of the glass of the mirror will have an effect on your focussing.
Replacing the seals (Interslice) should be done at the same time, in that way your camera will be in tip-top shape for the years to come.

Just get the mirror resilvered.

If you can't buy a replacement from Bronica you could send your mirror to a recoating service. These guy do it all the time for telescope mirrors. I'll bet it doesn't cost as much as you would think. It might be a good experience you write up to help other folks that aren't luck enough to have a camera manufacturer that can or will supply a replacement. The replacement might even cost more than having it recoated.

If you try this, stay away from the mirror refinishers that work on vanity type mirrors.

I have had mirrors re-silvered by Vacuum Coatings (Scientific Mirrors) http://www.vacuumcoatings.co.uk/vacuumcoatings.howtofindus.html

The quality of the work was very good and not expensive at about £15 to clean and re-silver two mirrors.
The turn around time was about a month.

Thanks for all the replies, I think I'll try the link yellowcat posted. Im astounded: £15 for two mirrors, I'll get this sorted right away. Sorry for all the questions but where can I buy new light seals?

Thanks

As I mentioned: Interslice on ebay, you probably have to send him a message as he does not have all his seals on ebay.
I got an universal set some month ago that is good for many jobs.

I'd suggest first trying to clean the existing mirror with denatured alcohol and lens tissue. Trying to replace the mirror may open a huge can of worms. John
