Thermal Scope or Night Vision, What Are the Differences and What to Choose?

Do not confuse a thermal scope and a night vision device, such as a monocular, they are two strictly different devices! First of all, a night vision scope is a device that amplifies light in the low infrared spectrum. It uses this residual light to restore, using a light amplifier tube, an image that is often colored because of the technology itself (the phosphor is generally green or bluish depending on the model).

A thermal scope, on the other hand, works differently. Its sensor captures the infrared emitted by the objects around us and then electronically recreates an image from this data. The cartography transcribed into the image can then be interpreted in various ways and in various colors depending on the purpose of your use. Therefore, thermal imaging can be used for various purposes.

Night vision is used to see at night, and a thermal scope is used to detect and interpret what is happening there… as well as, to identify what is happening in total darkness. Because there is no ‘let’s not forget, everything around us emits infrared in different wavelengths. This type of device is therefore ideal for identifying a target, following it, or simply observing its smallest facts and gestures in the most complete night and without any visibility.

How to Choose the Best Thermal Scope?

Before buying a thermal scope, certain characteristics must be taken into consideration before placing the order, such as its ability to capture infrared radiation and amplify light: the more structured this function, the higher the image quality, even in the dark.

Therefore, based on these technical characteristics, it will be possible to purchase the best thermal viewer model on the market that is able to satisfy different types of uses.

Magnification

The thermal scope currently on the market is equipped with 3x to 30x magnifications that can easily satisfy the needs of the most common uses. The magnification is connected to the observation distance which is measured in meters or feet and represents the maximum distance that you will be able to see with your viewer.

The product specifications will show two values ​​(3 × 30mm). The second refers to the objective diameter of the scope lens. Low magnification is useful for viewing a larger area rather than a single target. A thermal scope with low optical power produces a very large field of view but with a smaller image zoom.

Higher magnification has a smaller field of view but has noticeable detail in an image. A higher magnification level thermal scope is suitable for picking up a single target from a distance.

Lens coating

Different brands of thermal scopes have different lens coatings. This includes the coated lens for the multilayer lens, which is downright expensive. The brightness and clarity of the image captured by the monocular are very important attributes, which are significantly influenced by the type of lens coating.

There are four categories of thermal scope coating for lenses, including the aforementioned: coated, fully coated, multilayer, and fully multilayer. Fully multi-coated lenses reduce glare and improve brightness and clarity compared to multi-coated lenses. If you are looking for quality (better brightness and clarity), the fully multi-coated lens is the best choice even if it is expensive.

However, you can choose the coated lens to save money; it will still capture an image but with some hitches.

Optical quality

This is the most important feature to consider when deciding to purchase a thermal scope. Almost all the thermal scopes on the market are first-generation, but this does not mean that they cannot offer images of decent quality.

Dimensions and weight

The dimensions of the thermal scope are important factors depending on the use made of it. The size and weight of these devices vary according to the model but hardly exceed the kilo. The best scopes currently on the market are lighter and more compact but usually have a higher price.

However, it should be noted that a smaller and more compact design does not offer excellent performance. For example, a 10 × 25 model is compact and inexpensive but doesn’t offer the ideal image detail. To avoid the poor display, choose something larger.

Battery life

Almost all thermal scopes on the market work with high-quality batteries that offer 5 to 24 hours of service. However, it is important to check the battery life of the headset you wish to purchase. Some models allow charging via a mini USB port and this allows significant savings on the cost of batteries.

Scanning viewers

On the market, there are several models of thermal scopes that are displayed to represent the aura of heat emanating from the body or object. There are also thermal scanning visors, more precise than the model described above: the information captured is transferred to the infrared ray detector through two mirrors that are able to analyze, little by little, small surfaces but which, moving with a very precise, they slowly cover the whole view. The thermal signal is converted into electrical and therefore the scene is projected on a screen, just like a television image.

Additional Features

• Resolution: Higher resolution provides clearer and more detailed images. Look for scopes with a higher pixel count for better image quality.
• Refresh Rate: A higher refresh rate ensures smoother images, especially when tracking moving targets. Choose scopes with refresh rates of 30Hz or higher.
• Detection Range: Consider the distance at which the scope can detect heat signatures. A longer detection range can be crucial for spotting targets at a distance.
• Reticle Options: Different scopes offer various reticle styles and color options. Choose one that suits your preferences and provides clear targeting.
• Color Palettes: Thermal scopes often offer multiple color palettes for different viewing preferences. Some common options include white hot, black hot, and various color schemes.
• Digital Features: Look for additional features like digital zoom, image capture, video recording, and Wi-Fi/Bluetooth connectivity. These can enhance your overall experience.
