Infrared night vision devices are devices that use infrared technology and photoelectric conversion technology to observe targets in dark environments. They can convert infrared radiation that cannot be perceived by the human eye into images that can be seen by the human eye. They can provide high-quality images and videos in dark environments. They are important technical equipment and are widely used.

1. Working principle of infrared night vision devices

Infrared night vision devices can observe targets and obtain image information in complete darkness or when the ambient light conditions are very weak. Its working principle is to use the infrared radiation emitted or reflected by the object itself to illuminate the target in low light, no light or at night, and at the same time sense and receive the infrared radiation information generated by the illuminated object, and then amplify the signal and present it on the display screen for easy observation by the human eye.

2. Application fields of infrared night vision devices

The main function of infrared night vision devices is to expand the ability to detect objects outside the visible spectrum of the human eye, and to achieve target detection and monitoring tasks at night and in low-light environments. They are mainly used in the following fields:

(1) Military and security fields

Infrared night vision devices can be used to scout, monitor or search for targets at night or in bad weather, thereby improving the effectiveness of military operations. At the same time, it is also widely used in public security, fire protection, security and other fields, which can enhance the effectiveness of night patrols, investigations and rescue.

(2) Industrial field

Industrial production often requires inspection and maintenance of equipment or products in low-light or dark environments. Therefore, infrared night vision devices are also used in industrial fields such as robots, drones, mining, and oil drilling.

(3) Medical field

Hospitals, ambulances and other units need to perform first aid and surgery at night. Using infrared night vision devices in these scenarios allows doctors to clearly see and diagnose the patient's condition.

(4) Entertainment field

Due to its unique visual effects, infrared night vision devices are also used in some entertainment activities, such as night sightseeing, adventure activities, hunting, etc.

The optical lens system is an important component of infrared night vision devices, including objective lenses, prisms, pedestals, etc., which are used to collect light from surrounding targets and convert them into electronic signals. Chuangan Optoelectronics has independently developed a variety of objective lenses and eyepieces that can be used in infrared night vision devices and digital telescopes.
