Thermal Imaging Technology
Thermal imaging technology lies at the heart of every thermal scope, enabling users to detect and visualize heat signatures emitted by objects in their surroundings. Unlike traditional optical scopes, which rely on visible light to create images, thermal scopes operate by detecting the infrared radiation emitted by objects based on their temperature.
Explanation of how thermal imaging works:
Thermal imaging works on the principle that all objects emit infrared radiation, also known as heat. This radiation is invisible to the human eye but can be detected by specialized sensors within thermal scopes. These sensors convert the infrared radiation into electrical signals, which are then processed to create a visual representation of the scene.
Types of thermal imaging sensors:
There are two main types of thermal imaging sensors used in thermal scopes: uncooled and cooled. Uncooled sensors are more common and affordable, making them suitable for many applications. They operate at ambient temperatures and require less maintenance. Cooled sensors, on the other hand, offer higher sensitivity and resolution but come at a higher cost. They require cooling mechanisms to maintain optimal performance, typically using cryogenic cooling.
Importance of sensor resolution and sensitivity:
The resolution and sensitivity of the thermal imaging sensor play crucial roles in determining the clarity and detail of the thermal images produced by the scope. Higher resolution sensors can discern finer details and provide clearer images, enhancing target identification and recognition. Similarly, sensors with greater sensitivity can detect smaller temperature differences, allowing for better detection of targets in challenging environmental conditions.
Understanding the underlying technology of thermal imaging is essential for selecting a thermal scope that meets your specific needs and performance requirements. By considering factors such as sensor type, resolution, and sensitivity, you can ensure that you choose a thermal scope capable of delivering the level of performance necessary for your intended applications.

Purchase advice for thermal imaging devices
There are both the simplest models on the thermal imaging market that are ready to use immediately after the start button is pressed, as well as more complex specialized devices.
We advise you to choose a device with good overall specs , so you don't have to buy another one in the future just to provide some new features. However, since an infrared camera are a universal instrument for measuring temperature and analyzing thermal fields, you may be very tempted to use it for a maximum number of measuring and diagnostic tasks. This is the first thought you should get rid of when choosing a camera. When you buy a thermal imaging camera, the first thing you should clearly see is the main areas of its further application, the second is to decide on the budget.
Let's take a brief look at devices by area of application.
Thermal imaging cameras for hunting
The most popular thermal imaging cameras for hunting are:
1. AGM PYTHON TS75-640
2. Pulsar ThermionXP50
3. NVision Halo LR 640
Thermal imaging cameras for surveillance, security, and safety
The most popular thermal imaging cameras for surveillance are:
1. AGM ASP TM25-384
2. EOTech Model X640
3. AGM ASP TM35-640
4. Pulsar Helion XQ50
There are many other applications for thermal imaging cameras. But to understand and buy your ideal device, it is enough to take a closer look at the parameters of a particular camera. And if we have more or less figured out the areas of application, then we should look at the budget. What does the budget consist of, except the manufacturer's brand? First of all, the parameters.
The key parameters when choosing a thermal imaging camera are:
· viewing range;
· target size and thermal contrast;
· type and model of weapon (availability of interchangeable barrels and desire to use the sights on them);
· temperature conditions of use.
Now let's analyze all the parameters by points and define the key concepts affecting the image quality.
Field of view
This is a parameter of the thermal imaging camera lens that describes the size of space when taking a photo of an object. Most often it is measured in degrees. Simple geometry is used to calculate the basic field of view parameters. The smaller is the field of view angle, the further you may move away from the object without loss of image quality.
The bigger the field of view, the better the thermal imager works.
Zoom Capacity
Optical multiplicity and digital zoom are used to obtain a detailed image of objects at a great distance. Optical multiplicity for portable thermal imaging cameras usually does not exceed 4-5x, and digital zoom - 2x/4x/8x. On average, you can increase the ratio to 20x. The minimum multiplicity provides a wide field of view and displays the real size of the target.
Resolution and pixel size
The main parameter of the thermal imaging camera determines its sensitivity and image quality. The larger the size and resolution of the sensor, the more temperature points are displayed. At a resolution of 160x120 pixels, a thermogram of 19,200 pixels is displayed, and at a resolution of 320x240 - 76,800. The maximum value for commercially available thermal imaging cameras - 640x480 pixels, forming a picture of 307 200 points.
Wavelength
A spectrum of thermal radiation - invisible infrared range - 780-100 thousand nm wavelength.
You should therefore pay attention to the wavelength when purchasing a thermal imaging camera. It is important to realize that the bigger the wavelength, the better your thermal imaging camera will perform.
Calibration time
Calibration of the image allows you to equalize the temperature background of the microbolometer and eliminate deficiencies in the image (such as vertical stripes, "frozen" outlines of objects, etc.). Shortcomings appear in the process of operation of the microbolometer, as well as due to heterogeneous heating of the microbolometer. Calibration intervals depend on the duration of operation: the longer the thermographic instrument runs in continuous mode, the less calibration is required.
This parameter should be as small as possible. The faster the calibration is done, the better.
Display size
Why do I need a large display of my thermal imaging camera? First of all - the bigger the display, the less load on your eyes. This is because the bigger the screen, the more pixels it has. The best thing about modern screens is a minimum of pixels and, of course, the expansion. Take x960 pixels. This is good!
Lenses
The thermal sight lens differs from lenses of other devices operating in the visible spectrum of electromagnetic radiation. The lens of the thermal imaging camera lens must transmit thermal radiation, so it is made of germanium (Ge). This material is transparent to infrared waves.
Thermal sensitivity
An indicator showing the difference in recognized temperatures between neighboring points. The highest sensitivity is considered <30 mK, high <60 mK, and average <80 mK. AGM technology is typically registering at 35mk while other companies like Pulsar are usually at 40mk. The minimum difference that can be detected by the thermal imaging camera depends on its class. The smaller the difference, the wider the diagnostic capability of the instrument. Amateur infrared cameras capture a difference of 1-1.2°C, while professional thermal imaging cameras capture a difference of 0.02-0.05°C.
Refresh Rate
Indicator of the frame rate at which the image on the display changes. The standard range for portable thermal imaging cameras and sights is 7.5, 9, 25, 30, 50, 60 Hz. For inspection of territory and observation of fixed objects, the frequency may be minimal. For dynamic hunting, it is better to choose a thermal imaging camera with a frequency of 30-50 Hz.
Reticle Pattern
The use of a complex sighting grid implies distance estimation and bullet drop compensation – along a ballistic trajectory. The sighting grid is intended for precise aiming of the weapon at the target. Many reticles are available in all common thermal scopes on the market.
Battery
The duration of the autonomous operation is determined by the battery capacity and energy consumption. Portable devices have an average life of 4-6 hours. At minus temperatures, operating time is significantly reduced. We recommend lithium ion batteries when available, especially in the US. .Thermal imaging cameras can be equipped with rechargeable or conventional replaceable batteries. Most models have the ability to connect an external power supply for long term use.
Data transfer
The fact is that many thermal imaging cameras can be wirelessly connected to Apple mobile devices (iPad, iPhone, iPod). Most often it is Wi-Fi or Bluetooth. Find out if your thermal imaging camera has a connection.
Game identification
You should always be very careful with this technology. Technology is quickly reaching its limit, the more often it is used. The smaller the distance to the game, the more reliable the identification. use the rangefinder to carefully guess how far away a target might be. this feature is not a guaranteed distance and all shots should be taken with care.
