Will this work? Seems like it may conditionally align but not actually collimate because it doesn't look like it can accommodate several IPD settings.

Thanks for supporting Conditional Alignment!

I think you may find this to be a "comparator." That's the kind of thing used on Big Eyes. There is a lighted cross on the water tower in Port Orchard, Washington, facing the shipyard. Since Big Eyes don't have a hinge, something similar was used to align them. As far as I'm concerned, CA is as close as they would get with the setup.

I once bought a binocular collimator on the net. When it arrived it was a parabolic mirror in a cell. The "expert" who sold it to me just needed cash, I assume!

Cheers,

Bill

You know how the word "collimation" brings 'em out!

Bill :-O

PS This may be the drawing that started all that Bull. I had planned to make a few for sale, but never got around to it. The CRT is fuzzy because I was using InDesign for the first time and didn't have the drawing "embedded."

I think you could probably get as good conditional alignment with a home made scope, made for about $40.

With a reticle of some kind at the eyepiece, a Newtonian (backwards) or an SCT is a collimator. The obstruction doesn't matter because it's where the axle will be, anyway.

I've been thinking about making one from a C-11. It's just that having sold the real thing . . . TWICE, I'm just being ornery. In addition, nobody (well, not enough) wants anything repaired anymore. I'm not buying into all that some people see as "great," but you can buy a new--really good--(read: good enough) binocular for the cost of have a qualified technician do the work. In addition, there are so many "qualified" technicians around who . . . Aren't.

I would only trust Cory.

PS There are probably a number of your army's MK 4 lying around your country.

I like his description that this collimator is used by all the big German and Japanese manufacturers.

I have worked for both the German ones (still work for one) and have never seen anything like this !!!

I have never seen one either! It looks like a home brew to me. Also, note the adjustment screws. With this set-up, one has to wonder, "Is the collimator, collimated?"

The seller can say what he wants. But, it looks to me . . .

"Good advertising need not be accurate, or even meaningful; it needs only to be BELIEVED."

Many of the Germans and most all (reputable) Japanese and Chinese manufactures use the Fujinon U.B.M.M. (Universal Binocular Measuring Machine).

PS Gary, Are you the Leica/Zeiss engineer I met over on CN?
