Terminology to Know
In the world of sport optics Canada residents should know some important terms that come in handy when looking for and using night vision equipment. To help you understand the information you’ll be presented with, some of these terms are outlined below along with their definitions.
Sensitivity: Sensitivity related to how much infrared light a device can detect.
Noise: Noise interrupts night vision and can cause blurred and distorted images.
Gain: Gain is the ratio of visibility compared to infrared output, which measures the signal’s amplification.
Anode: An anode is an electrode with a positive charge that pulls electrons to the phosphor screen.
MCP: MCP stands for micro channel plate and it amplifies photoelectrons in night vision devices.
Phosphor screen: Phosphor screens absorb electrons and produce visible light images.
Passive devices: These devices use natural infrared light to produce clear images in night vision equipment.
Active devices: These devices use infrared illuminators, also known as IR, to provide additional light and produce clearer images.
ITAR: ITAR stands for the International Traffic in Arms Regulations. This organization regulates the sale and export of certain technologies outside of the US.
Now that you have more information on what night vision goggles are, you’ll be able to do adequate research and find the equipment you need to go out at night with confidence.
