Bino issue with Olympus CH-2

[Krishan]

Hi out there,

I have a serious issue with my old but beloved CH-2: Dropped it today, and it fell on the the left eyepiece holder with the diopter correction (thanks god oculars were not inserted). The holder broke off including the short aluminum tube that centered the holder in the correct position. I checked if I can glue it back, but something got off the optical axis. When I put it back flat I have double images with the image in the left eyepiece about 7 or 8 percent left from the right one. If I correct the left image by tilting the holder it is visibly crooked from it's normal position. Anything else seems to be alright. Also checked the prisms inside, but they have not come loose. Do you have any repair suggestions except buying a new bino head or sending it to Olympus service?

Best regards

The first step to getting the best possible advice is to post pictures of the damage. The more the better, and with as much detail as you can capture.

You may want to consider a used binocular. I think you will find them priced very inexpensive and it sounds like yours is pretty bad.

However, unless the seller is knowledgeable you wont know if a used binocular has collimation issues until you get it so pay attention to the return policy.

Let us know how you make out.

Hi Kirby,

great tip, thank you. I would have taken the risk even at no return/refund policy and high shipping cost to Germany, where I live. But a closer look at images and description of this item shows that the top cover of the trino is dented and even cracked. Too many doubts that collimation is still okay with such a mechanical impact.

Hi together, thank you for your answers. Looks like I have found a replacement at an affordable price here in Germany. By the way: Some users from a german forum told me this issue seems to be typical for that type of bino tube. The left ocular tube has turned out to be some kind of predetermined breaking point for Olympus tubes of that generation.

Krishan,

I’m in Europe and have a mono ocular you might be interested in as an interim solution to bridge the gap till you have found a new bino/trino.

And if you find a new One I’m interersted in the bottom lens of your bino

Hi deBult,

thank you for your offer. Currently it looks like I will get a replacement for my bino next week here in Germany. If not, I can send you the bottom lens as a "rent" for the mono tube if you tell me how to disassemble. Otherwise I would be happy selling it to you as a replacement part at an affordable price.

Best regards

The CH2 is finite, and while there is a flat glass plate at the bottom of the head I do not think there is a lens there from looking at one I have handy.

[deBult]

There is a relay glass plate at the bottom of the CH2 bino and mine is cracked.

I would have thought the main purpose would be to keep dust out, though I suppose it'd mess up the expected distance to remove it.

Hope the new head works out ok.

Have been able to locate a spare Bottom relay lens with help of Carl.
