Thermal Imaging Sight
Night vision devices can be divided into two types: the increased image tube night vision device (traditional night vision device) and the infrared thermal imaging night vision device.
What is the increased image tube night vision device and infrared thermal imaging night vision device
1. Increased Image Tube Night Vision
It is a night vision device in the traditional sense, which can be divided into one generation to four generations according to the algebra of the image tube. Because a generation of night vision devices can't meet people's needs in image brightness enhancement and definition. So now it is rare to see a generation and a generation + night vision device. Therefore, if you want to achieve real use, you need to purchase the second generation and above of the increased image tube night vision device.
2. Infrared thermal night vision monocular
Infrared thermal imaging night vision devices are a branch of thermal imagers and are technically demanding in production, so there are very few manufacturers that can produce thermal imaging night vision devices around the world. Among them, it includes ULIRVISION.
The main difference between traditional night vision and infrared thermal imaging night vision
1. In the case of all black, the advantages of infrared thermal imaging night vision are obvious.
Since the infrared thermal imaging night vision device is not affected by light, the infrared thermal imaging night vision device is exactly the same distance under all black and ordinary light. Traditional night vision devices must rely on an auxiliary infrared source in the case of all black, and the distance of the auxiliary infrared source can only be as far as 100 meters.
2. In the harsh environment, the advantages of infrared thermal imaging night vision are obvious.
In harsh environments such as fog and rain, the viewing distance of traditional night vision devices will be greatly reduced. However, thermal imaging night vision is less affected.
3. In the environment where the light intensity varies greatly, the advantages of infrared thermal imaging night vision are obvious.
We all know that traditional night vision devices are afraid of glare, although many traditional night vision devices have strong light protection. However, if the brightness of the environment changes greatly, it will have a great impact on the observation. But night vision thermal imagers are not affected by light.
4. Traditional night vision devices have advantages over infrared thermal imaging night vision devices in terms of target recognition capabilities.
The main purpose of infrared thermal imaging night vision is to find targets and identify target categories.
