Any suggestions for shades for Swarovski 10x25B pocket binoculars? (To stop internal reflections)
ship
Hi
I recently bought a pair of Swarovski Pocket size binoculars (10x25B),
but am having trouble with them.
Several years ago, following much research at the time, I bought a
pair of EL 10x32, which I am extremely happy with, but I needed
something genuinely pocket-sized.
I only did a moderate amount of research this time (and did a back to
back test against a pair of Leicas) and although the optics are
absolutely gob-smackingly good they have a MAJOR flaw. There is a huge
amount of internal reflection when pointed even vaguely towards the
sun! In the low Autumnal sun this is proving to be a SERIOUS
pain... :^[
However I was disappointed to discover when I visited the Swarovski
website that they do not sell any kind of shades. I am extremely
tempted to build some out of cardboard or something, but before I do
so I was wondering if anyone had experienced the same problem and what
can be done about it(?)
- Any thoughts?

All that money. What a shame. (diabolical laughter)
The only answer is to jury-rig something. There's a device that can
be attached to camera flashes to direct the flash. Maybe that would
work. (It uses velcro)

what you have in mind, but they might serve as inspirations for a
design that would work.

Not quite the same problem, but my solution might help. It's here:

(Not the same because in my case the bins were OK but the light gets in
between eye-piece agains the spectacles and my eyes. So the shade goes on
the eye-piece end not the objective end.)
Mike.

What about a call to Swarovski? I have found them very helpful in the
past (but I only have the EL 10X42 similar to you - not the pocket
version). If you acquired through a dealer - how about asking there.
Perhaps they can suggest some kind of filter. Good luck!

I was going to suggest (also) seeing if Sharon Stiteler
http://www.birdchick.com/ might have an idea, she is a Swarovski scope fan.

You might want to check out birdforum.net. They have a binocular section
with many
experts in binoculars. It's free to register. It's a message board.

Shades (cardboard tubes) will do the trick. But I can't resist a
puerile pun...
You might consider 'flocking'. It seems apposite.
Joking aside, if most reflections are from the internal tube walls,
flocking will do a good job. It's a common practice among amateur
astronomers. Like this;
http://www.tomhole.com/Flocking.htm
It's a council of perfection of course, not necessarily a practical
solution. But if you like that sort of thing, you might be able to
adapt the idea for binos.

Get the flock outahere!

I dare say. I've got a set of bins downstairs (don't remember what
brand) that got water in them--taking them part, drying them out and
doing something with white grease for some reason (I've forgotten what
or why) I had converted them to junk.
If you have some experience with optics, have at it. If not, beware.

I dunno about "flocking paper"--"flocking to me is a process where you
paint something with stickum and blow a fuzzy powder into the stickum.
But it dies suggest that maybe some matte paper rolled into a cylinder
might work.
(But I stick to my strongly held belief that anything that pricey ought
not to have that kind of a problem--I mean we are talking
first-telescope optics problems here.)

Flock paper is moderately stiff paper covered with glue, after which
flock is applied electrostatically. That causes the pieces to stand on
end, creating a surface like velvet. Especially with oblique incidence,
there is very low reflection from such a surface. I use it for lining
home-made telescope tubes, but I wouldn't advise it for binoculars. (1)
Pieces of flock occasionally fall off the paper and get onto the glass.
It's not easy to remove. You don't want to be opening binoculars because
they can tend to fog up after that, and in any case, you really want a
dust-free area like a clean hood (laminar flow hood) to work in. (2)
Do what you can to remedy the flaw from the outside. If it were my
problem, I'd ask Swarovski for guidance.

It's what Jerry Avins described, paper to which a kind of black
velvety surface is applied.
I'd never attempt to dismantle high quality binos--or low quality--,
for that matter.
Once you violate the integrity of the O-ring seals, their waterproof/
fogproof properites are gone along with the dry nitrogen inside them.
You will void the guarantee, too. Swarovski would have every right to
refuse to honor it.
