B&L B Stand

[Scoper]

Could someone show the underside of the B&L B stand?

I have one that is missing the complete mirror mount.

Thanks

I should mention that mirror part that was included has a typical concave mirror and a translucent (flat?) reflector. The translucent reflector is tarnished (delamination?)..any suggestions as to what to replace the surface with?

Thanks

You could try white paper. It's not extremely reflective and really designed to have the Nicholas shining right one it.

Thank you very much for posting great detailed photos.

I spent over a hour searching on the Web with no luck..apparently amateur microscopy is not a popular subject.

In regards to the search for a replacement for the translucent reflector, the solution seems to be the many types of packaging for food stuffs we are blessed with.

So far the candidates are a foil cover for cashews, a chocolate chip cookie package, a foil seal from a peanut butter jar, the unpolished side of aluminum foil and the foil side of a hot cocoa package. A foil surface is used widely to maintain freshness of the product.

The B&L mirror is very well made with tight tolerances for the mirror/mount..I suspect any attempt to try to remove the translucent mirror will unwanted damage to the mount. At this time, I am planning mounting the replacement reflective surface to the mounting using contact glue..a far more gentler solution.

Here's the underside of mine:



In case it would help you to have a parts diagram, you can find one on pages 22–23 of this older manual or page 8.8 of this newer one.

Two different mirrors were available for these stands. Yours sounds like the older one—shown in @BramHundingNematoes' images—which has a grey frame with a concave mirror on one side and a flat, frosted surface on the other. The newer one—shown in my image above—has a black frame with two sets of mounting slots, and both the mirror and the frosted sides are flat. I don't get the impression that one is more functional than the other (though I haven't had an opportunity to compare them), but if you wanted to source a replacement mirror, the newer one may be easier to locate. It also would probably not be too difficult to DIY a replacement mirror, since the method by which it is attached to the stand is so simple.

I think that the unpolished side of aluminum foil will probably be the best of the options you are considering (and nothing better comes to mind). It will be a bit shinier than the original mirror, though. @BramHuntingNematodes' suggestion of white paper would be a good alternative to try if the unpolished side of aluminum foil doesn't diffuse your light well enough.
