Product DescriptionProduct DescriptionIn the realm of optics, cut-off filters act as precise gatekeepers, playing a pivotal role in controlling light. These filters selectively allow light within specific wavelength ranges to pass through while blocking others, enabling accurate manipulation of light.The operation of cut-off filters relies on their unique optical structures and material properties. When light strikes the filter, its internal molecules or atoms interact differently with various wavelengths. Those wavelengths matching the filter's transmission criteria pass through smoothly, while others are absorbed, reflected, or scattered. This selective transmission and blocking mechanism allows cut-off filters to perform essential functions across a wide range of optical applications.SpecificationProduct NameCut-off FilterTransmittanceT>90%Thickness1.1 ±0.1mm or CustomDimension ToleranceCustomAOI0°Surface Quality (SQ)60-40 Scratch & DigClear Aperture (CA)90%Blocking350-2000nm Except for Transmission BandOptical Applications?In scientific research, cut-off filters are indispensable tools. For instance, in spectroscopic analysis, researchers need to precisely examine light signals at specific wavelengths to study the structure and properties of materials. Cut-off filters help eliminate interference from unwanted wavelengths, allowing only the target wavelengths to reach the detection equipment—greatly enhancing measurement accuracy and reliability. In astronomical observations, these filters also prove invaluable. By filtering out stray light from Earth's atmosphere or other celestial sources, they enable astronomers to clearly observe specific wavelengths emitted by distant celestial bodies, leading to more accurate data collection and deeper insights.In industrial manufacturing, cut-off filters find extensive use as well. During semiconductor fabrication, photolithography requires precise control over the wavelength and intensity of light. Cut-off filters ensure that only the desired wavelengths reach the silicon wafer, maintaining the accuracy and quality of the patterned circuits. In laser processing, such filters remove unwanted stray light generated by lasers, improving beam purity and focus, resulting in more precise and efficient machining.Company ProfileTianjin Fushi Optics Co., Ltd.Tianjin Fushi Optics Co., Ltd. is a comprehensive optoelectronic enterprise integrating R&D, production, sales, and after-sales service.
