Here's a pair of WWII binoculars I just repaired for a repeat customer.  These were made for the Lend Lease Program and went to Great Britain as indicated by the upward pointing arrow and the location of the reticle in the right barrel.

The left prisms were broken and all  lenses were foggy. 

I disassembled the binoculars for a thorough cleanup and lubrication.

True collimation was achieved for all IPD range after reassembled all parts.

Now the binoculars function like new like they were in WW2.

Nice job. Was it difficult to find a replacement for the broken prism? (since I know absolutely nothing about replacing and aligning prisms.)

Not very difficult to find prisms for some of the WWII binos. Some places still sell old stocks.

For smaller binoculars I use Fuji UBMM. For larger ones I use a special collimator that can perform collimation up to 150mm aperture or more.

Hello Mark,

 

I think WA is an abbreviation for Washington State, USA.  

 

Stay safe,

Arthur

Hi Ivan, I guess you are a professional and know even the most modern tools. In a Swarovski video I saw a technician looking at an LCD screen from 30-40cm away with binoculars.
Do you know if there is a collimator of that type, or do you have any idea what the technician was doing?

Thanks.

I tried to find it, but as usual when you look for it you can't find it. smirk.gif 
It was still a PC monitor ... maybe a 27-32" Apple

They're mine and I love what he did to them.  I now have a rare piece of history that functions like the day they were made together with an original case~!

These are pro kits usually used by factory.
Personal service won't use a monitor, however the function is the same.

So, can you answer my question?
Are you aware of the existence of a collimator or similar device, which uses a PC monitor (observing it with binoculars)?

Ivansky said he uses a Fuji UBMM collimator which has a screen, which I believe the above images he provided are taken of.

 

Bill Cook gave me a demonstration of the Fuji UBMM that was installed at Captain's in Seattle years ago.  I wonder if Ivansky purchased his UBMM from Captain's when they left the bino business, since they are local to him.  question.gif

Hi Rich,

Yes I purchased the UBMM from Captain's  when they sold their business in 2020.
