About ATN

In 2012, ATN launched its first line of Digital Night Vision devices (monoculars) with Ultra Bright core technology. Annually with their innovative technology, ATN is providing a variety of thermal and night vision devices such as scopes, binoculars, and monoculars.

ATN launched its fourth generation optical devices in 2018 that are configured with an Obsidian 4 core with Dual Processor. Besides, it enhances image processing abilities and offers high-speed performance in every condition. 

These newly launched products possess special features such as HD video recording, wireless streaming, ballistic calculation, One-shot zero, image stabilization, and laser ranging. These updated features make your hunting easier and that are useful for newcomers in the hunting field. 

Devices that are incorporated with thermal technology are widely used for General purposes, Security purposes, Military purposes, and Industrial applications.

How ATN Thor 4 Works

Thermal Sensor in ATN Thor 4 Thermal rifle scope works by receiving heat energy (Infra-Red Rays) from the source and then modified it into a color view that is visible to human eyes. 

The lens present in this riflescope collects the infrared rays which are then scanned by thermal sensors, the signal sent to the microprocessor for further processing. 

The function of the microprocessor is to convert the different values of heat(IR rays) into different colors, and this process happens within a few fractions of a second. The thermal riflescope is a camera that takes pictures of infrared light and then translates it into visible light.
