As a material with special properties in the field of optics, HWB760 infrared filter glass plays an important role in many industries. It can cut off the spectrum before a specific wavelength and has good transmittance to the infrared spectrum after 760nm. This unique optical property makes it an indispensable component in many application scenarios.
Security monitoring field
In the field of security monitoring, HWB760 infrared filter glass is widely used in surveillance cameras. Surveillance cameras need to obtain clear images under various light conditions. At night or in low-light environments, infrared fill lights are usually used to provide lighting. HWB760 infrared filter glass is installed in front of the camera lens, which can effectively block visible light and only allow infrared light to pass through. In this way, the camera can use infrared light to form an image, thereby realizing night monitoring. Even in a dark environment, the outline and activity of the object can be clearly captured, which greatly improves the performance of the monitoring system under low-light conditions and provides strong support for ensuring public safety and property safety. For example, in surveillance cameras on city streets and security monitoring systems in residential areas, HWB760 infrared filter glass is silently playing a role, helping security personnel to detect abnormal situations in time.
Biometric field
Fingerprint recognition machine: In fingerprint recognition technology, HWB760 infrared filter glass helps to improve the accuracy and stability of recognition. Fingerprint recognition equipment usually adopts the principle of optical imaging. By irradiating the fingerprint surface with light, the reflected light carries the fingerprint texture information and is received and analyzed by the sensor. However, visible light in the environment may interfere with fingerprint imaging, resulting in blurred images or inaccurate feature extraction. HWB760 infrared filter glass can filter out visible light in the environment, so that the device only receives infrared light. Because the reflection characteristics of grease and moisture on fingerprints are different from those of the surrounding skin, the fingerprint texture will be more clearly presented under infrared light, thereby improving the accuracy and speed of fingerprint recognition and reducing the misjudgment rate.
Face recognition system: In the face recognition system, HWB760 infrared filter glass also plays an important role. Face recognition equipment needs to accurately capture the characteristic information of the face for recognition. In complex lighting environments, such as strong direct light or backlight, visible light imaging may cause facial shadows, reflections and other problems, affecting the recognition effect. With the HWB760 infrared filter glass, the device can use infrared light for face imaging. Infrared light can penetrate some ambient light interference and clearly present the contours, facial features and other features of the face. Even under harsh lighting conditions, it can ensure the normal operation of the face recognition system and improve the reliability and accuracy of recognition. This is of great significance in the identity authentication process of access control systems, attendance systems and some places with high security requirements, such as airports and banks.
Infrared sensing equipment field
Infrared sensing toilets, faucets, hand sanitizer devices: These daily infrared sensing devices also cannot do without HWB760 infrared filter glass. The infrared transmitting tube inside the device emits infrared light. When the human body approaches, the infrared light is reflected back by the human body and received by the infrared receiving tube. The HWB760 infrared filter glass is installed in front of the receiving tube, which can effectively filter out the stray light in the environment and only allow the reflected infrared light to enter the receiving tube. This can avoid the interference of ambient light, improve the sensitivity and accuracy of the induction, ensure that the device can respond in time when someone approaches, and realize functions such as automatic flushing, water or hand sanitizer, which brings convenience to people’s lives and improves the level of hygiene.
Infrared thermometer: The infrared thermometer measures the temperature of an object by detecting the infrared radiation emitted by the object. The HWB760 infrared filter glass plays a role in screening useful infrared signals. There are various wavelengths of light in the environment. The HWB760 infrared filter glass can block visible light and unnecessary infrared light, and only allow infrared light of a specific band related to the temperature of the object to pass through and enter the sensor of the thermometer. This enables the infrared thermometer to measure the temperature of the object more accurately and reduce the error caused by external light interference. It plays a key role in measuring human body temperature in the medical field and detecting equipment temperature in the industrial field, providing reliable data support for temperature screening, equipment failure warning, etc.
Optical measurement and analysis instrument field
Optical measurement instruments: In some optical measurement instruments, such as spectrometers, HWB760 infrared filter glass is used to select infrared light in a specific wavelength range for measurement and analysis. Spectrometers detect and analyze light of different wavelengths to obtain information such as the composition and structure of a substance. HWB760 infrared filter glass can filter out unnecessary wavelengths of light, allowing the instrument to focus on analyzing the infrared spectrum region after 760nm, improving the precision and accuracy of spectral analysis. For example, in material science research, through infrared spectrum analysis of materials, information such as the chemical bond structure and molecular vibration mode of the material can be understood, thereby evaluating the performance and quality of the material. HWB760 infrared filter glass helps the instrument obtain purer and more accurate infrared spectrum data, providing a powerful analytical means for scientific research and industrial production.
Analytical instruments and equipment: HWB760 infrared filter glass is also used in some chemical analysis instruments and biological analysis instruments. For example, in infrared gas analyzers, the filter glass is used to screen out infrared light wavelengths absorbed or emitted by specific gases. Different gases have specific absorption peaks in the infrared spectrum. By detecting the intensity and position of these absorption peaks, the type and concentration of the gas can be determined. HWB760 infrared filter glass can remove interference from other wavelengths of light, allowing the analyzer to more accurately detect the infrared signal of the target gas, and achieve accurate monitoring and analysis of harmful gases in the environment and gas components in industrial production processes, which is of great significance for environmental protection, industrial production process control, etc.
