There are two main types of night vision devices: image intensifier tubes and thermal imagers. Image intensifier tubes take the tiny amount of light that is present, even in moonless conditions, and amplify it to produce a visible image. Thermal imagers detect the infrared energy that is emitted from warm objects and convert it into a visible image.
Image Intensifier Tubes
The heart of an image intensifier-based night vision device is the photocathode tube. This vacuum tube contains an electron emitter and an electron multiplier. When photons (particles of light) hit the photocathode, they knock electrons loose from its surface. These electrons are then accelerated by a high voltage potential difference across the tube and directed toward the electron multiplier.
A thermal imager detects infrared radiation and produces an electronic signal that is then converted into a visible image. It does not require any external light source such as moonlight or starlight. Instead, it sees the infrared energy emitted from warm objects. The warmer an object is, the more infrared radiation it emits. All objects emit some infrared energy, even those that appear cold to the touch.
When shopping for night vision devices, it is important to understand the difference between image intensifiers and thermal imagers. Each has its own strengths and weaknesses. Image intensifier tubes are more sensitive to light than thermal imagers and can provide better image quality in low-light conditions. However, they are also more susceptible to damage from bright light sources, such as flashlights or flares. Thermal imagers are not as sensitive to light, but they can see in total darkness and are not damaged by bright light sources.
Now that you understand how night vision devices work, you can start shopping for the right one for your needs. Keep in mind that image intensifier tubes are more sensitive to light than thermal imagers and can provide better image quality in low-light conditions. However, they are also more susceptible to damage from bright light sources, such as flashlights or flares. Thermal imagers are not as sensitive to light, but they can see in total darkness and are not damaged by bright light sources. Choose the type of night vision device that best fits your needs and budget, and make sure to do your research before making a purchase.
Ultimately, the best way to choose a night vision device for airsoft is to consider your individual needs and preferences. Some people may prefer an image intensifier tube due to its greater sensitivity to light and improved image quality in low-light conditions. However, others may opt for a thermal imager, which can see in total darkness and is not affected by bright light sources. Ultimately, you should carefully weigh all of your options before making a final decision about which type of night vision device is right for you.
Factors to consider when choosing a night vision device
When shopping for a night vision device for airsoft, there are several factors you should consider. These include the sensitivity of the device to light and its ability to produce a clear image in low-light conditions. You will also want to consider its durability and how it is affected by bright light sources. Other important considerations include cost, functionality, and ease of use.
Ultimately, whether you choose an image intensifier tube or thermal imager will depend on your individual needs and budget. It is important to do your research before making a purchase so that you can find the best night vision device for your needs.
