Night vision devices are divided into gen 2+/3/4 night vision devices, etc. according to different image intensifier tubes. However, the most common ones are gen 2+ night vision devices. So Why are the gen 2+ image intensifier tubes the best selling?
What’s the parameters related to the image intensifier tube? The first is FOM which is calculated as Resolution*SNR. It’s used to describe the overall performance of night vision devices. The higher the FOM , the clearer and brighter the image. Besides, the resolution is a parameter standard for Image quality of the same level. The sensitivity is related to the brightness and contrast of the image. The SNR is related to noise and distortion of image. When night vision devices are used for wild adventures and animal protection, the products of gen2+ can fully meet people's needs, so people like to buy this product.
Among the most common gen 2+ and 3 products, the main difference is the cathode tube material of the image intensifier tube. The gen 2+ generally uses multialkali, while the gen 3 uses GaAs. The two types of image intensifier tubes have different capabilities for light sensitivity and the gen 2+ technology is more mature and the price will be cheaper.
Generally speaking, for most people, a gen 2+ night vision device is enough. Good performance and low price are its biggest advantages. If you have higher requirements for night vision devices, you can choose Europe gen3 image intensifie tubes with higher FOM.
