A thermal imaging scope is a device that uses temperature differences to detect objects and form images. It is often used in hunting, monitoring and other fields. UNIVISION will guide you on how to choose a suitable thermal imaging scope. The important indicators of thermal imaging scopes are as follows;
UV-TS650R2
UV-TS335R2
1. Resolution
•The resolution determines the clarity of the image. Common resolutions include 384x288, 640x512 and 1280x1024. Higher resolution means clearer images, but the price will also be higher.
•Pixel pitch: This refers to the distance between two adjacent pixels, usually measured in microns (μm). Smaller pixel pitches can provide more detailed images. Common thermal imaging detectors have a pixel pitch of 12μm/17μm. There are also some 8μm detectors, but the price is very high and is still in the small batch testing stage. It will take some time before mass production and market use are achieved.
2. Detection distance
•Thermal sensitivity: Also known as the noise equivalent temperature difference (NETD), it indicates the minimum temperature difference that the device can detect. A lower NETD value means that the device is more sensitive to temperature changes and can better identify targets. At a longer distance, a thermal imaging scope with a smaller NETD value can identify objects more clearly, which can help hunters find targets more easily.
•Maximum detection distance: Different thermal imaging scopes have different maximum detection distances. If you often hunt at long distances, it would be more appropriate to choose a model with a longer detection distance. The current conventional rifle shooting distance is generally about 800 meters, so when choosing a lens, you can consider using a 12μm, 384*288, 35mm field of view 7.5°×5.8° lens or a 12μm, 640*512 resolution 50mm field of view 7.2°×5.8° lens. Within this field of view, with a better field of view width, you can instantly find the target and see the target within hundreds of meters.
3. Refresh rate
•Frame rate: Indicates the number of times the image is updated per second. Common frame rates include 25/30Hz and 50/60Hz. Higher frame rates can provide smoother images, which is especially important in fast-moving scenes.
4. Battery life
• Battery type: Common battery types include rechargeable lithium batteries and disposable batteries. Rechargeable batteries are more environmentally friendly, but need to be charged regularly; disposable batteries are easy to replace, but the cost is higher.
• Battery life: Long-term hunting may require thermal imaging scopes to work continuously for several hours. Therefore, it is very important to choose a model with long battery life.
5. Distance measurement and trajectory calculation
Thermal imaging scopes equipped with distance measurement function can help hunters better calculate the target distance and hit the target more accurately. Our TS series is equipped with 1km distance measurement to meet most usage scenarios
The trajectory calculation function and distance measurement function can assist hunters in better aiming. The TS series supports custom trajectories, and hunters can use various guns to match different trajectories
6. Weight and size
• Portability: Lightweight and compact thermal imaging scopes are more suitable for long-term carrying and use. When choosing, consider whether it is easy to install on your gun and will not add too much burden. UNIVISION's second-generation scope can achieve a total weight of only about 600g without a battery.
• Durability: Considering the complexity of the outdoor environment, choosing a thermal imaging scope that is waterproof, shock-resistant, and low-temperature resistant can ensure that it works normally under various harsh conditions. UNIVISION TS series thermal imaging scopes can work normally in an environment of -30℃~60℃. The maximum impact resistance is 1200g/0.4ms.
7. Additional functions
• Video recording and photography: Many modern thermal imaging scopes are equipped with video recording and photography functions, which are convenient for hunters to record precious hunting moments. The TS series has a built-in 32G storage card that can save a large number of pictures and videos
• Wireless transmission: Wi-Fi or Bluetooth connection can transfer images to mobile phones or other devices for easy sharing and storage. UNIVISION TS series can directly connect to mobile phones or computers and view real-time images
• Smart functions: UNIVISION TS series supports target locking and object tracking functions, and it is not easy to lose the target when the object moves quickly.
8. Brand and after-sales service
•Brand reputation: Choose a thermal imaging scope from a well-known brand, which usually has better quality assurance.
•After-sales service: Understand the brand's after-sales service policy, including warranty period, repair service, etc. Good after-sales service can provide timely support when there is a problem with the equipment.
9. Budget
•Cost-effectiveness: Choose a suitable thermal imaging scope according to your budget and needs. High-end models usually have more features and better performance, but they are also more expensive. Mid-range and entry-level models can also meet the needs of most users.
Conclusion Choosing a suitable thermal imaging scope requires comprehensive consideration of multiple factors, including resolution, detection distance, refresh rate, battery life, weight and size, additional features, brand and after-sales service, and budget. I hope the above information can help hunters choose the thermal imaging scope that best suits them.
