Characteristics and application of infrared night vision mirror

Infrared night vision objective lens is a key part of the optical system of the infrared night vision device. Its main function is to collect and focus on infrared light and faint visible light, and convert it into humanly recognizable images.

Infrared night vision objective lens is one of the key factors in the performance of the infrared night vision device, and the lens is the core part of the objective lens. It is usually composed of composite optical glass lenses, which can accurately focus light on the CCD or CMOS chip to form a clear image. In addition, filters should be set up in the infrared night vision mirror to filter unnecessary light to ensure the clarity and brightness of the imaging.

I. Characteristics of infrared night vision mirror

The following is a brief introduction to several characteristics of the infrared night vision object lens:

1. It has a wide field of view. There is a spotlight on the surface of the infrared night vision instrument objective lens, so that the light can better converge on the CCD or CMOS chip. And the objective lens adopts an optimized optical design, which can provide a larger field of view and enable users to obtain a wider range of observation.

2. Strong adaptability. The lens surface of the infrared night vision lens is covered with a variety of filters with different functions, including IR filters, low-illuminance steering filters, strong light filters, etc., which can meet the needs of different environments and observations.

3. It has high resolution. The objective lens is designed with aspheric lenses or composite lenses. Its design and manufacturing process are very strict, which has a great impact on the performance and cost of the instrument. On infrared night vision instrument objective lenses, high-quality lenses are coated with high hardness, which can provide clear observations under various conditions and reduce reflection and scattering light loss.

4. It has multiple focal lengths. Infrared night vision objective lenses can provide a variety of lenses with different magnifications according to different needs, such as 2x, 4x, 6x, 8 times, etc., supporting different focusing choices from close to long distances. At the same time, the mechanical adjustment multiplier and high-quality optical system can well realize the zoom function of the lens.

II. Application of infrared night vision objective lens

The objective lens of infrared night vision devices is widely used in situations where targets need to be observed in low-light environments, such as military, security and semiconductor production.

1. Military field: Infrared night vision objective lenses are often used in the military field, such as detecting enemies and detecting distant targets in low-light environments.

2. Security field: Infrared night vision objective lenses are also widely used in the field of security, such as night monitoring sites to detect intruders or unknown objects.

3. Semiconductor production field: In some semiconductor production processes, due to the need to observe small defects on the wafer surface, infrared night vision technology will also be used to observe the wafer surface to ensure the quality of production.
