Night Vision Equipment

Looking for a good set set of Night Vision Binoculars for a good price. are any of them on ebay a good buy?

You get what you pay for. Night Vision is best evaluated by what "generation" it is typed as. First generation is just IR (Infrared) capable and requires an IR light source. Second generation has a low grade image intensifier tube and is IR capable. The cadillac is the Third generation. Completely passive light amplification and IR capable. You can drive or navigate in almost total darkness with third generation. There are enough vendors for Night Vision Equipment on Ebay that the prices are competitive. Your best course is to decide your price range and search within that parameter.

I have a camera that doesn’t have night vision so can i get it on my camera some how

I really don’t think but it your camera picks up Infrared light ( witch I don’t think it will ) you could mount a infrared light on it but I really don’t think your camera can do that sorry

i want the cheapest gen.2 night vision..please give the price of it too:D
idk it could be binocular,goggles, or monocular

binos 2.0

I’m looking to buy a piece of hardware that can work in complete darkness and that has a relatively far range of sight what would be the best product or things to look for in a product.

However, some of us DO take pictures in extreme low light, or NO visible light at all..

Night Vision Equipment needs SOMETHING to amplify in order to excite or charge the viewing screen. With a good night vision scope, star light is often enuf. Any kind of moon light is plenty.

2nd generation night vision equipment is what you will find at most places selling them. Very good equipment can be had for under $500 US$ and some very nice scopes are under $200 US$, and some under $100 US$.

Most of these are from Russia (or China) and either have been re-packaged to look not so military or left as they are and look like a military piece of equipment. Some even have a invisible IR light source with them to see in TOTAL darkness..

1st generation night vision equipment goes back to WWII and Korea. The imagining tubes were very infrared sensitive and needed a IR light source to light up the area.

Today, the 2nd and 3rd generations only need star light to work. In a complete dark room (building, cave, etc..) nothing sees unless there is some kind of "light".. Now, this ‘light’ can be a small Mag Light with a IR LED in place instead of a light bulb. No one sees anything, but your seeing the whole room. Trouble is, 3rd generation equipment is still very expensive and a nice scope can be well over $1,000 US$.

With the 2nd generation equipment is found even at places like Walmart, many sport shops and even Harbor Freight tools, it’s not hard to get one and start playing.

Look for a FAST and large lens. Like in photography or astronomy, a lens of f2.8 is rather fast, but a lens of f1.8 is even faster. Then the diameter is to be considered and the larger the better. Some night vision scopes come with a IR emitter, a invisible light source. These can be made easy enuf by Googleing – infrared plastic or filters and acquiring a piece large enuf to cover your light source. Make sure it is equivalent to a Kodak 87c or Hoya RM-90 type filter.

These filters are totally black. They let NO visible light thru and only pass the IR. With a filter over a spot light you can see 100′s of yards with many night vision scopes.

Now, photography with a scope. Some of these scopes actually come with camera adapters. Trouble is, the image seen thru the camera is often dull and weak. But the fact is, they can work and it is up to you to figure it out.

Digital cameras are VERY sensitive to IR light, however, they have a IR blocking filter over the chip that sees. Remove this filter and the camera can see by IR light, either by your light or that of the sun. If you use the camera in daylight you MUST put this 87c filter over the lens (or a different filter like it that allow IR light to pass). Now, if you have a modified camera that lets IR in and you put a IR filter over your flash.. Bam, instant pics in the dark and all that was noticed was the sound of the camera going off. Maybe…

None of this is really hard, just takes some trial and error in working out either equipment and/or exposures.

Web cams are the same but these often have a small glass filter you can remove by hand and you now make a IR sensitive camera from it. The modified web cam, a dark room and a IR light source and you watch the action on your computer from there or in another room. Again, Harbor Freight sell’s BW and color infrared cameras for under $45 US$ and all you need is a standard video input on a TV or computer to view and record.

If something has been missing from your life, something like sweet ocean air, the feeling of sand beneath your toes, or the distant beat of a steel drum, then it might be about time to take a Caribbean vacation. This is a vast area with many choices, but there’s one that’s just right for you, so start looking.

The Caribbean is the region of islands that includes the Virgin Islands, the Bahamas, Barbados, Puerto Rico, the Dominican Republic, Aruba, and several others. No single place stands out as the most beautiful or accommodating, but everyone has their favorite. Soon you will too, so start perusing the options at hand.

Not that every Caribbean beach is interchangeable, but it is highly likely that you’ll be pleased with whichever island you choose to stay on, so long as the accommodations meet your standards, that is. By picking out a vacation rental that suits your personality and vision of a dream trip, you’ll be setting yourself up for success.

Perhaps you’ve been planning to sweep your partner away for a few romantic days alone. A St. Maarten condo located on an acre of tropical gardens with a view of the Atlantic Ocean might be just what you’re looking for. You’ll be close to the beach, where snorkeling, scuba diving, and suntanning will fill your day. Out of the water, you’ll find a butterfly farm, horseback riding, duty-free shopping, and many fine dining options to fulfill the requisite candlelight dinner.

Make yourself at home in the fully-equipped kitchen and whip up some hors d’oeuvres, to be enjoyed with rum cocktails out on the private deck, of course. Take a soak in the whirlpool tub before snuggling into the king-size bed, and then enjoy the best sleep you’ve had in years. Your beloved will feel pampered, and you’ll feel proud of yourself for being the one to initiate such a pleasing experience.

If the Cayman Islands strike your fancy, then snatch up a villa on the famous Seven-Mile Beach. Again, you’ll have every opportunity to frolic in the ocean and easy access to more civilized pursuits as well. Stores and restaurants are just down the road, as well as water sports shops that will rent equipment and instruct you in your under-the-sea adventures. If golfing is your passion, then you probably know that the Cayman Islands are the home of the Links at Safe Haven, an 18-hole course that many consider to be the best in the Caribbean.

Your villa will be, amazingly, just across the street from this golfer’s paradise, so don’t worry about paying for transportation. At the end of your most scenic round ever, you’ll be happy to stroll back “home” for a snack and a shower before heading back out for a night of island entertainment. Never before have you felt so taken care of; it’s almost as if this vacation home was tailor-made just for you.

Visiting the Caribbean should be all about taking it easy, putting responsibility on hold, and savoring the simplest of pleasures. Enjoying the comforts of a vacation rental fits nicely into this design, so investigate the possibilities before you make your way to Jamaica, St. Lucia, or wherever the trade winds set you down.

Go online to locate the Caribbean Vacation Rental that will bring out the best in you and your ultimate island getaway.

Cataract is a cloudy or opaque area in the lens of the eye. Cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil. The lens works much like a camera lens, focusing light onto the retina at the back of the eye. The lens also adjusts the eye’s focus, letting us see things clearly both up close and far away. Most cataracts are related to aging. Cataracts are very common in older people. Cataract can occur in either or both eyes. It cannot spread from one eye to the other. Cataracts may be present at or shortly after birth. These are called congenital cataracts. Cataracts are classified of three types permary is nuclear cataract is most commonly seen as it forms. This cataract forms in the nucleus, the center of the lens, and is due to natural aging changes. It cannot spread from one eye to the other.

Secondry is cortical cataract, which forms in the lens cortex, gradually extends its spokes from the outside of the lens to the center. Many diabetics develop cortical cataracts.Third is subcapsular cataract begins at the back of the lens. People with diabetes, high farsightedness, retinitis pigmentosa or those taking high doses of steroids may develop a subcapsular cataract. Congenital cataracts can also be caused by infections affecting the mother during pregnancy, such as rubella. They are also associated with metabolic disorders such as galactosemia. Congenital cataracts risk factors include is inherited metabolic diseases, a family history of cataracts, and maternal viral infection during pregnancy. Congenital cataracts may be inherited. The gene for such cataracts is dominant (autosomal dominant inheritance), which means that the defective gene will cause the condition even if only one parent passes it along.

Causes of Cataract

1.Injury or trauma.

2.Genetic factors (congenital cataracts).

3. Exposure to ultraviolet light.

4.Diet high in antioxidants beta-carotene (vitamin A).

5.Heavy alcohol consumption.

Symptoms of Cataract

1.Cloudy or blurry vision

2.Problems with light, including headlights that seem too bright.

3.Faded colors.

4.Poor night vision.

5.Frequent changes in prescription for eyeglasses or contact lenses.

Treatment of Cataract

The only treatment for cataract is surgery to remove it. Cataract surgery is very successful in restoring vision. In fact, it is the most frequently performed surgery in the United States, with over 1.5 million cataract surgeries done each year. There are 2 types of surgery that can be used to remove lenses that have a cataract First is Extracapsular surgery consists of surgically removing the lens, but leaving the back half of the capsule (the outer covering of the lens) whole. High-frequency sound waves (phacoemulsification) may be used to soften the lens to help removing it through a smaller cut second is Intracapsular surgery involves surgically removing the entire lens, including the capsule.

I spend alot of time in the mountains and woodland area and usually at night. I am looking to buy some night vision but am not sure on strong reliable manufactures.
Please help.

Thanks!!

Hi.. Before you select a binocular, it’s good quality and the explanation for your search. Hopefully can help you find the best! Check it out..

me and a friend are messing around tonight and have night vision on a camera and want to do sumthin cool

Point it at the night sky, expecially Jupiter, the moon, and the stars. Play with infrared remote controls. Go to a dark city park where people like to make out in their cars…

I have a Night Vision Monocular that works on infrared principle. when I’m in the dark room, changing the film in my camera, I’m naturally having a tough time because it’s dark and want to use my monocular. But, I’m concerned. Is infrared going to burn my film? Anyone?

It depends. I use an IR goggle headset in my darkroom. Its wavelength is 1060nm, well into the far infrared. The films I use are standard panchromatic films, which are insensitive above about 700 or so, very safely short of any kind of infrared. I never have a problem.
Having said that, prolonged exposure to 1060 would undoubtedly have some effect, probably an overall background density. Films are ultimately sensitive to just about all radiation of exposed for a long enough time. But the kind of weak, temporary exposure associated with normal darkroom film handling under weak 1060nm IR has little risk.
Your biggest problem is going to be trying to use a monocular, which magnifies. Everything close to you, on your counter for instance, will probably be badly out of focus and very hard to see.

I was wondering if there are any hazards to using Infrared Night Vision Goggles.

no
