What is the application range of long wave infrared lens?

2024-12-27

Like long wave infrared lens these things are basically products used in the industrial field, most of us have not seen nor heard, you can say that in life is not very common, but they also play an irreplaceable role in the industrial industry, then we must first understand the use of long wave infrared lens range of application, Follow us to find out more.     So from the professional field of view, long wave infrared lens, also known as IR lens, it can be used for special purposes corresponding to infrared, but also as an ordinary lens. In this way, its application range will be very wide, and according to different use occasions, the long-wave infrared corresponding lens can be flexibly used with traditional color cameras, black and white cameras, day and night cameras. These are very convenient for users. Because in black and white cameras, there is no infrared cut-off filter, which is limited, so the use of long-wave infrared corresponding lenses can effectively improve the image quality. This is because sunlight also has infrared light in its spectrum, so even in daylight conditions, the image of a black and white camera will be disturbed by infrared light. So this is also a complementary model, to help each other, in order to play a greater role. The long wave infrared lens of the surveillance camera lens can focus infrared light and visible light, so the image will be clearer. And the long wave infrared lens uses a special ED lens, which solves the problem of "running focus" of ordinary electric zoom lenses under infrared light conditions. Make the picture quality more clear and beautiful. At the same time, the long-wave infrared lens is through the special coating design and the use of special optical materials, so that the light in the 350-950nm band can be well corrected for color difference, and according to the corresponding IR infrared corresponding technology, and does not need to work again 24 hours a day to focus. Therefore, most monitoring systems can obtain clear images with the help of infrared light sources. This is more convenient for subsequent work. At the same time, the long-wave infrared lens adopts the new optical design 璻 and the special optical glass material, that is, LD optical glass technology, so that the focal plane deviation of visible and near-infrared light can be well eliminated. We insist on using high quality materials, making high quality products, taking responsibility for customers, putting customers first, and creating a win-win situation. We have professional customer service here to answer the relevant professional knowledge for you. And has consistently maintained high quality services, to thousands of consumer and industrial products to add a successful color, has been widely recognized by the industry, to achieve a win-win vision with partners.

What are the characteristics of long wave infrared? Infrared is an electromagnetic wave with a frequency between microwaves and visible light. It is a general term for radiation in the electromagnetic spectrum with a frequency of 0.3 THz~400 THz and a wavelength of 760 nm-1000 um in vacuum. So, what are the characteristics of long-wave infrared? What are the characteristics of long wave infrared? 1, the frequency of infrared is low (frequency from low to high order: radio, microwave, infrared, visible light), giving a feeling of heat, produce a thermal effect. 2, if the infrared ray can penetrate atoms and molecules, it will cause the expansion of atoms and molecules, resulting in the disintegration of atoms and molecules. Infrared low frequency, insufficient energy, far from the effect of atomic and molecular disintegration. So infrared rays can only penetrate the gaps between atoms and molecules, but not inside them. 3, because infrared rays can only penetrate the gap between atoms and molecules, it will accelerate the vibration of atoms and molecules, making the gap wider, that is, increase the energy of thermal motion. Macroscopically, matter is melting, boiling, vaporizing, but the physical and chemical properties of matter (atoms and molecules themselves) do not change. 4, you can use this infrared excitation mechanism to barbecue food, so that organic polymers denature, but can not use infrared to produce photoelectric effect, can not change the nucleus inside. 5. Do not use radio waves to grill food. The wavelengths of radio waves are too long to penetrate the gaps in organic polymers, let alone denature them for the purpose of cooking food. 6, the shorter the wavelength, the higher the frequency, the greater the energy, the greater the range of wave penetration. The longer the wavelength, the lower the frequency and the lower the energy, the smaller the range the wave will penetrate. For the range of diffraction energy, the opposite is true: the longer the wavelength, the stronger the diffraction power; The shorter the wavelength, the weaker the diffraction power.   Long-wave infrared What are the operational methods of long-wave infrared therapy? 1. The patient adopts the correct posture and exposes the irradiated area. 2. Check whether the irradiated part has a normal sense of warmth. 3. Move the lamp to the top or side of the illuminated part, the distance is generally as follows: 4, in the local or whole body light bath, the two ends of the light bath box should be covered with cloth. 3 to 5 minutes after power, the patient should be asked whether the warm feeling is appropriate; The temperature in the light bath should be kept at 40~50. 5, after the treatment, dry the sweat of the irradiated area. Patients should rest indoors for 10 to 15 minutes before going out. Long wave infrared need to pay attention to what? 1. Patients should not move during treatment to prevent burns. 2. When the irradiation part is close to the eyes or the light can reach the eyes, apply gauze to cover the eyes. 3, when the affected part has a warm sensation disorder or fresh scar sites and skin grafts are irradiated, small doses should be applied, and the local reaction should be closely observed to avoid burns. 4. Areas with obvious blood circulation disorders or vascular dilation are generally not exposed to infrared radiation.

Vehicle-mounted lens refers to the optical lens installed on the car to realize various functions, mainly including internal view lens, rear view lens, front view lens, side view lens, surround view lens, etc. As the main component of the car camera, the car lens market is also developing rapidly. The wavefront vehicle lens is all independently developed. It has the characteristics of compact structure, light weight, good shock resistance, sealing and waterproof, etc. It has excellent optical performance in the temperature range of -20℃~+60℃, which fully meets the special application environment of vehicle lens . The detection distance is long, the lens can match a variety of detectors, and there are a variety of focal lengths to choose from. The optical lens for in-vehicle infrared night vision developed by Wavefront has a compact structure, good shock resistance, and a wide range of non-heating temperature. Even if the line of sight is obstructed by the environment, if the road is dark, there is smoke, etc., the auxiliary night vision system can still detect the pedestrian in front, presenting a clear road ahead for the driver. It is especially suitable for distance detection and obstacle recognition of unmanned vehicles. With many years of professional experience and knowledge accumulation, using high-quality lens components and materials, specially designed automotive shortwave infrared series lenses suitable for the car auxiliary industry. • Satisfy the resolution and ensure clear imaging. • Large field of view, up to 123 degrees, can reach both sides of the road • MTF performance • High relative aperture, F number up to 1.2 • Use 1064nm band, through fog. • The ghost image is eliminated during the optical design, so there is no ghost image.
