I would prefer NVG bino to IR, cause IR can see rough shapes not full detail.. NVG can get at beach road one shop.. they can order for you.. BUt warnig... the pricetag will make you faintOriginally posted by tek_koh:U can go to tangs at orchard
they got this bino, cnt rem the specs or brand, but has IR capabilites bout $2000
The "high class" shop which sells replica toy guns and real M16 bipods and scopes.Originally posted by acwire_2125:So Beach Road does sell NVG? Any idea which shop and how much?
Where?Originally posted by chanjyj:The "high class" shop which sells replica toy guns and real M16 bipods and scopes.
How much arh... lol... I forogt.. the moment I heard the price I purposely "forgot" to save me from fainting
go army market look around.. confirm you will find the shop cause it i so diff from the surrounding shops.. I dun go army market anymore so forgot the excat location.Originally posted by wonderamazement:Where?
Yes... I have looked at other shops selling identical itemsOriginally posted by SpecOps87:Know the boss of that shop, guy called Louis. But the stuff they sell...friggin balls to the wall expensive man.
Er... can educate this noob?Originally posted by SpecOps87:I suppose the 1st and 2nd Gen stuff which are reliant on ambient light to operate are "legal" as compared to the military types which do not require an IR beam nor anything to illuminate.
I think... no ambient light is almost impossible to encounterOriginally posted by beavan:if there is TOTALLY no ambient light, then u turn on the IR beam, which illuminates the area. seldom happens, with stars and the moon.

[b]Generation 0- The original night-vision system created by the United States Army and used in World War II and the Korean War, these NVDs use active infrared. This means that a projection unit, called an IR Illuminator, is attached to the NVD. The unit projects a beam of near-infrared light, similar to the beam of a normal flashlight. Invisible to the naked eye, this beam reflects off objects and bounces back to the lens of the NVD. These systems use an anode in conjunction with the cathode to accelerate the electrons. The problem with that approach is that the acceleration of the electrons distorts the image and greatly decreases the life of the tube. Another major problem with this technology in its original military use was that it was quickly duplicated by hostile nations, which allowed enemy soldiers to use their own NVDs to see the infrared beam projected by the device.
Generation 1- The next generation of NVDs moved away from active infrared, using passive infrared instead. Once dubbed Starlight by the U.S. Army, these NVDs use ambient light provided by the moon and stars to augment the normal amounts of reflected infrared in the environment. This means that they did not require a source of projected infrared light. This also means that they do not work very well on cloudy or moonless nights. Generation-1 NVDs use the same image-intensifier tube technology as Generation 0, with both cathode and anode, so image distortion and short tube life are still a problem.
Generation 2 - Major improvements in image-intensifier tubes resulted in Generation-2 NVDs. They offer improved resolution and performance over Generation-1 devices, and are considerably more reliable. The biggest gain in Generation 2 is the ability to see in extremely low light conditions, such as a moonless night. This increased sensitivity is due to the addition of the microchannel plate to the image-intensifier tube. Since the MCP actually increases the number of electrons instead of just accelerating the original ones, the images are significantly less distorted and brighter than earlier-generation NVDs.
Generation 3 - Generation 3 is currently used by the U.S. military. While there are no substantial changes in the underlying technology from Generation 2, these NVDs have even better resolution and sensitivity. This is because the photo cathode is made using gallium arsenide, which is very efficient at converting photons to electrons. Additionally, the MCP is coated with an ion barrier, which dramatically increases the life of the tube.
Generation 4- What is generally known as Generation 4 or "filmless and gated" technology shows significant overall improvement in both low- and high-level light environments.
The removal of the ion barrier from the MCP that was added in Generation 3 technology reduces the background noise and thereby enhances the signal to noise ratio. Removing the ion film actually allows more electrons to reach the amplification stage so that the images are significantly less distorted and brighter.
The addition of an automatic gated power supply system allows the photocathode voltage to switch on and off rapidly, thereby enabling the NVD to respond to a fluctuation in lighting conditions in an instant. This capability is a critical advance in NVD systems, in that it allows the NVD user to quickly move from high-light to low-light (or from low-light to high-light) environments without any halting effects. For example, consider the ubiquitous movie scene where an agent using night vision goggles is “sightless” when someone turns on a light nearby. With the new, gated power feature, the change in lighting wouldn’t have the same impact; the improved NVD would respond immediately to the lighting change. [/b]
