Description
IR infrared filter glass CPL / polarizing film integrated solution: high cutoff rate + high polarization degree, infrared imaging quality upgrade
Optical IR infrared filter glass with CPL (circularly polarized light) / polarizing film is a high-performance optical combination product. IR infrared filter glass can selectively transmit or cut off infrared light of a specific band to achieve precise regulation of the infrared spectrum; CPL / polarizing film can effectively control the polarization state of light and eliminate interference such as reflected light and glare. The combination of the two can significantly improve the imaging quality and optical signal processing capabilities of the optical system in complex environments.
Core advantages
Precise spectrum control: IR infrared filter glass has the characteristics of high transmittance and high cut-off depth. It can accurately filter specific infrared bands according to different application requirements, such as achieving high transmittance in the 800-1100nm range, while effectively suppressing visible light and other stray light, providing pure infrared light signals for infrared imaging, infrared temperature measurement and other applications.
Eliminate glare interference: CPL/polarizing film can effectively eliminate glare caused by reflection from smooth surfaces such as water and glass, reduce ambient light interference, and improve image contrast and clarity. In outdoor shooting, industrial inspection and other scenes, the details of the target object can be clearer and the color more realistic.
Stable optical performance: The use of high-quality optical materials and advanced coating technology ensures that the filter glass and polarizing film can still maintain stable optical performance under different environmental conditions such as temperature and humidity, and it is not easy to show performance degradation after long-term use.
Flexible combination and application: According to the specific usage scenarios, different specifications of IR filter glass and CPL/polarizing film can be flexibly selected for combination to adapt to a variety of optical equipment, such as camera lenses, surveillance cameras, infrared thermal imagers, optical detection instruments, etc.
Application scenarios
Security monitoring: At night or in low-light environments, IR infrared filter glass combined with CPL/polarizing film can enhance the surveillance camera’s ability to capture infrared light, while eliminating interference from ambient reflected light, improving the clarity and recognition of the surveillance image, and helping security personnel accurately identify targets.
Infrared thermal imaging: Used in infrared thermal imagers to filter out unnecessary spectral components, allowing thermal imagers to more accurately detect the temperature distribution on the surface of objects, and play an important role in power inspections, industrial equipment fault diagnosis, medical testing and other fields.
Photography: Helps photographers eliminate reflections from objects such as water and glass when shooting outdoors, enhance the blue saturation of the sky, and enhance the layering and visual effects of the picture; in infrared photography, combined with infrared filter glass, unique works of art can be created.
Optical instruments: Such as spectrum analyzers, optical measuring instruments, etc. This combination product can improve the detection accuracy and stability of instruments for specific spectral signals and ensure the accuracy of measurement results.
