Hi, I have a pair of ex army binoculars, no make on them unfortunately but they have lovely glass in them, 3D effect when viewing and nice and bright,made in japan and are rubber. .
As they are ex army, I have got no information on them and one thing I don't know is why both eyepieces barrels can be extended in and out about an inch or so ,I have no idea what this is for or does?, would anybody on the forum know?.
Thanks

Hi and welcome.

If you mean eye cups then it is for use with and without spectacles.

A photo would help identify the binocular.

Regards,
B.
 
They are either eye cups which extend up/down to get proper eye relief. Or it could be that you have an IF bino where each eye piece focuses individually. Is there a center focus wheel?
 
What does the inscription say?

For instance 8x42.
Waterproof?

Seems like extending eyecups for use with or without glasses.

Why do you think the binocular is ex army?

Regards,
B.
 
Hi, no inscription. Ex army friend got me them...if you know what I mean.
You do seem right about extending eyecups, I googled that and seen a pair with same cups and info how to use extending eyecups, which was helpful.
Thanks again everyone.
 
There seems to be something marked on the top of the focus wheel.

The binocular is a roof prism centre focus.
Rubber armoured.

Dioptre setting on right eyepiece by twisting.

Looking at reflected white light what are the colours of the reflections?
Are there any white reflections?

What is the diameter of the glass in the front, the objective end?

What is the size of the small light circle at the back when pointed at a bright scene? The exit pupil size?

Regards,
B.
 
It seems to be the Pyser E8x42RM, as shown in two images from a PDF.

Pyser states that it is '. . . the ONLY British manufacturer of night vision goggles and monoculars for land forces.'
See at: Pyser Optics ā€“ A specialist British manufacturer and supplier of precision optical and electro-optical equipment and associated components.

Presumedly the various binoculars of Asian manufacture are to enable the company to offer a wider range of optical products,
to those primarily interested in NV equipment.

Hi John A , good find , my bins are exactly like your pic. Also it enabled me to see a number that I never noticed before, the number on mind is 8/n02076.(not sure if that's a 0 or o after the n) As I said earlier , my binoculars are made in Japan.
Still surprised you found that info .
Cheers.
 
Glad I put this post on here John and you seen it. I was pleasantly surprised at the glass in the Pyser E8x42RM and compared to what the British army are now using, as I asked my friend if he could get a pair of 12x50 for me , I was expecting the same quality but received a pair of Praktica "Falcon" binoculars, when I received them I messaged him to say "really" and he said they were now using off the self ones
