You must have realized that a thermal scope’s detection, recognition, and identification distance varies depending on the target size and posture. A detailed description of target size with detection, recognition and identification range will always be helpful than only claiming on the detection range itself. What critical factors of a thermal scope affect detection/recognition/identification range? The larger the area of the thermal radiation projected by the target onto the FPA, the more temperature data it could absorb, the more detailed picture the system could get, and the easier it to distinguish the target. As the target gets further, the area of the target’s thermal radiation projected onto the FPA will become smaller, and the number of pixels covered will decrease. When the amount of the pixel covered by targets on the FPA is equal to the amount of the DRI range, the target distance is equal to the DRI distance.
Some high-quality thermal devices use germanium glass lenses. They have a high refractive index, allowing the IR range of wavelengths to pass through and reach the sensor that identifies a target. Because of the rarity of the germanium metal, it costs 1500 dollars per kg; and that’s just the cost in its raw form. When you add the price of refining and processing germanium into a high-performance long-range thermal surveillance lens, the total cost of the equipment increases exponentially. Also, it depends on the aperture (the F-number of the device); the lower the F-number is, the more expensive the lens costs. For example, an F1.0 lens is always costing more and has better performance than an F1.2 lens. See even more details on thermal binoculars supplier.
What is the detection range of your product? According to Johnson’s criteria, ‘detect’ means ‘if an object is present or not.’ So, the detection range depends on what specific target you are observing. For thermal imager, with the same size of the lens, the smaller pixel pitch of the thermal detector, the longer distance you could detect. Taking a human-size target as an example, the detection range of our 12-micron and 75mm lens model could reach as far as around 3600m. Likewise, ‘recognition’ is defined as ‘being able to see what type of object it is.’ It means being able to make the distinction between a person, a car, a truck, or any other object. With our 12-micron and 75mm lens model, the recognition range could reach as far as around 1200m. For the detection range of all models, please refer to our specification sheet for more details.
