Yukon Optics - Popular Questions, Answers, Tips & Manuals

fixya site doesn't do phone calls any way if you got it in 2/14/2014 why did you not do somethinh about the problem immediately and not 4 years later

Why . interested in making an expensive paper weight

Check the warranty on the link below,, if the cost of the repair is more than half the price of the unit,, consider getting a new one, If it is a current model you can always take it back. http://www.walmart.com/ip/Yukon-Advanced-Optics-25023-Viking-2X-Night-Vision-Binoculars/4382096?action=product_interest&action_type=title&placement_id=irs_top&strategy=PWVUB&visitor_id=85147291684&category=0%3A4125%3A546956%3A4155%3A649999%3A5179&client_guid=9a5160ec-3354-4e1f-a8c0-f145eac5b6ef&config_id=2&parent_item_id=13133249&guid=d8367b65-45a7-4cdc-824e-9fd2de574de1&bucket_id=irsbucketdefault&findingMethod=p13n

..the electronics inside may need calibrated

As long as you use a special lens cleaning cloth it will not hurt the lens, it is the same cloth that is used to clean eye glasses or any camera lens. You can buy these almost anywhere.

Hello, don't worry about it. It is HV to the image intensifier tube. The battery voltage goes through control circuit then to ccfl inverter (here is were dc voltage is switch on and off and switch dc voltage is step up by toroid coil that has two input and only two out puts). By impulsing the coil with two different switch dc voltage on the input this make the current lag the two different phase voltage by 90 degrees. Here is where the strange noise is coming from. The toroid coil is encased in iron case and if half of this iron case is loose, it makes case vibrate so the noise.


Now, the voltage come out of the toroid coil is switching dc (one could call it AC because that what AC voltage is, it switch between positive to negative) this voltage is about 300 to 900 switching DC voltage. This voltage will be applied to a 1/2 wave voltage multiplier (this voltage multiplier with have anywhere four four stages to 10 stages depend on what the input voltage to multiplier is.

Low the voltage out of the ccfl inverter the more stages the multiplier will have.



Now, the voltage multiplier will double the voltage per stage to need image intensifier tube voltage of 12000 to 45000 volts---DC switching or AC what ever one wants to call it. This voltage will bit you but it doesn't have a lot current associated with it, the current would be in the 10 to 15 ua (micro-amps) 1/10X6 amps.



Now, you know. GB...stewbison

these units need a very small amount of light to work at all, They amplify this small amount of light, with no light at all they have nothing to amplify! the infra red is a source of light so it can amplify that, At night they amplify street lighting or moonlight or starlight etc, hope this helps,

Take it apart by peeling away rubber cover and then remove two mounting screws. Carefully split cases and see where parts are arranged just in case they shift. Laser and lens frequently get jarred loose ESP in a golf cart environment. Place laser and lens if loose back in mounts and gluon in place with superglue or equivalent. Make sure to get no glue on lenses. Reassemble and it should be good to go again. Total time. Ten minutes maybe.

Hello Paul

The Yukon Futurus series best in optics and body construction design to create a high quality, professional binocular.Yukon's patent protected Rubber Armored™ body, which mixes ergonomic design with rugged good looks.Yukon's Limited Lifetime Warranty.

Hello, clean the outside of the lens with a good optical cleaner. If you have, then trying adjusting the focus for each eye. Try both ends of this binocular at one eye at time; such as, left first, then the right eye until there are focused. That is if you can focus the optical end and they leave you with the eye lens for focus. Let me know how it works out. stewbsion

Hello, take some switch cleaner--Radio Shack- and spray just a small amount into the switch. Did you installed the battery correctly with the polarity be correct. Does the battery compartment have any type of corrosion? If this does help then there is something else wron with it. stewbison

Here we go. Take it to electronic repair facilities. See if the can replace the LED IR. Now if they want. Call Yukon NV Optics and see what the charge, normally these companies have flate fee they will charge. They really don't make it easy for the owner to repair these NV binocular. Basically, the binocular will almost be totally taken a part. stewbison

Hello, let do this. IR illuminator has a montary switch, that is when you push it comes on, and when you release it the IR goes off and it has a red LED to indicate the IR illuminator is being activated.

When you turn you binocular on there will be a green LED activated. This switch is DTSA---double throw sing activated. That is, one throw of the switch it turns on the binocular, the throw will turn off the binocular.

Also within the control panel there is timing circuit to keep the IR illumniator on for ten second the shuts off. Make sure you have the right switches etc. Let me know, then we can brain storm on this matter. stewbison

Don't IR illuminator in the dark room. Turn on a small light in one of the corner; such as, a small light bulb. increase ambient light a little at a time until you can focus. You flooding the dark room with IR illumination which will reflect everywhere in there. This might take care of the fuzziness in the monocular. stewbison

That's OK. When IR broke off did it leave any hole into the cavity of the scope? If it did, use some black anodized aluminum (or black plastic) plate 1/16 or smaller and mold it and fit to where it broke off only if there are holes.

Once the plate been fitted tightly. Now you drill some holes. The number of drill holes is up to you. Go down to your local fastener business, the carry all kinds of screws, machine screw, bolts, nuts, everything that you might need. Get the machine screws that are the self threading. They will look like a little machine screw with SAE threads but it will be tapered on end with a small notch cut in the end. This way you will not have to use a tap to thread the holes.-----One more thing here, pre-tap the drill with self tapping machine screws. This way you can clean out the scope cavity Then apply a thing layer of black rubber cement to the cover plate and then screw the machine screws. The length of the machine screw are critical. You don't want the to long where the reach far into the scope cavity. It could disrupted the flow of light to the NV scope.

Now, for a IR lumination. Get head light with one high luminating bulb. Get an IR lens and have it fitted to the head light, now you have IR lumination. Simple, hey. stewbison

Hello, most of these night vision devises are repaired by the companies that offer to sell and service. It almost impossible to find someone other than the dealer to repair them. You try Morrision Optic they have big web page on the Internet. A little warning here. These companies they sell NV devises are not necessarily the manufacture of these NV devise. Russian make a lot of these NV devises for US NV companies.


I repair them also but it hard for me to get parts, and I can make other parts if I can find some dealer that will sell me parts For a 1st generation cheap Russian image intensifier tube will cost about $175 each and sometime I can get them cheaper. GB....stewbison
