I have a pair of nikon travelite ex binoculars that I have dropped twice. they have serious double vision, worsening on shaking. i've tried to open the casing by removing 3 screws but it seems glued shut. any tips on how to open it to access the prism which must be loose (needs more than collimation). thank you. keith

Hi Bob,

You'll need to call Nikon and likely send your binoculars to their repair facility in Torrence, CA.
Nikon's phone number is 1-800-645-6687. This type of repair should be covered under their no-fault repair/replacement policy.

They are out of collimation, probably because one of the prisms has shifted due to a knock.

FixYa did not replace your friend's binoculars- this site just gives advice and has no connection with manufacturers or retailers. You should contact the manufacturer or perhaps the place you bought them.

Common problem with binoculars after a knock. One of the prisms has shifted, putting them out of collimation (alignment). If they are very high quality or collectible they might be worth fixing. It is likely to be expensive. I have done a few pair myself, but only when it was uneconomic to have it done professionally (I have ruined a few too).

Hello Scott

While I am mostly a camera expert , I have seen the problem that you are describing. Inside the camera there is a little reflector which is used to invert the picture and focus it to the viewing eyes.

These reflectors are stuck to the camera casing using epoxy and the problem is that with time the epoxy becomes brittle and cracks. When it is cracked , the lens will move out of it's fixed posistion but the epoxy does not always break loose fully which is why you do not hear any rattle.

You could attempt to open it up and glue the lens back into posistion using some new epoxy , but you could possibly have some problems with the screws of they are not standard.

In this case ask a jeweler to repiar the binocular for you as this should not cost much to repiar...no more than $15.

Kind Regards

Well, you can't, but a repair guy can. The body actually splits into two to access the collimation screws. Not a job for the faint hearted as the plastic has a tendency to crack if you don't prise them apart at the right spot.

I'm supposing by eyepiece you mean the rubber or plastic eyecup. The eyepiece is the whole unit that contains the lens. Nikon has a service center in many countries. If you have one in your country then they can order the part. I have ordered from Nikon. They find the part number if you tell them your model and can email you an order form. Alternately Binoculars.com is very good to deal with as is Adorama Camera in New York. Both will sell internationally.

They can be fixed but not at home. You need a collimator to properly align the optical paths. If under warranty send them back. If not get a quote first repairs are expensive and you may be better off with a new one.

Your glasses have had a hard drop or jar- they are out of colluminatiom send them to Deusch Optics in Nevada

well lets see..if i was you which im not i would take my dog for a nice walk on the ocean look at the sea and say bye bye binos.aaah the lobsters and crabs will have a nice time trying to get a single image.ok if you really want to have them fixed. send them for an estimate to a good repair shop...that should only take about 5 weeks and cost you $30.00 for shipping and an estimate.and they only cost $20.00

You have to open each side ( nikon travelite covers just unclip ) to get to the 4 prisms. Once opened to clean make sure you do not break the glue that holds down the prisms ( move the prisms in their seats and your alignment is out ). Clean with window cleaner and isopropanol to finish.
