Infrared Narrowband Filter (BP)

Product Introduction:

MULTI IR Narrowband Filter offers core advantages like high center wavelength accuracy, narrow and steep passband, high transmittance within the passband, deep cutoff depth, and extremely high edge transition steepness. It is widely used in gas detection and analysis, as well as in smart homes, environmental protection, industrial and agricultural production, etc. Customization of center wavelength, passband width, cutoff range, size, and spectral parameters is available.

MULTI IR IR Narrowband Filter (also known as IR Narrow Bandpass Filter) is a high-end optical filter product specially designed for accurately capturing specific narrow-band infrared light. Its core function is to allow only infrared light within an extremely narrow wavelength range (usually between a few nanometers to tens of nanometers) to pass through, achieving deep cutoff of light at other wavelengths, and featuring extremely high wavelength selectivity and channel isolation.

This product adopts ion beam sputtering coating technology and high-precision optical processing technology, selecting high-quality dielectric materials and optical substrates (silicon, germanium, gemstone, infrared quartz, zinc sulfide, zinc selenide, chalcogenide glass, etc.) to ensure core performances such as high peak transmittance, low insertion loss, high cutoff depth (up to OD6 or more), and good temperature stability. As a representative category of custom optical filters, it is widely used in fields requiring high wavelength accuracy such as astrophotography, gas detection, biomedical imaging, laser communication, and spectrum analysis. In astrophotography, it can filter out interfering bands such as sky glow and light pollution, clearly capturing specific infrared signals of celestial bodies, such as planetary observation and nebula imaging; in the field of gas detection, it can accurately match the characteristic absorption bands of different gases such as CO, CO₂, CH₄, CH₃CH₂CH₃, CH compounds, CH₂F₂, PH₃, NO, NO₂, alcohol, SF₆, SF₄, SO₂, realizing high-precision detection of gas concentration; in biomedical imaging, it can target and select specific infrared signals of biological tissues, improving imaging contrast and diagnostic accuracy. MULTI IR IR Narrowband Filter supports comprehensive customization services, including personalized adjustment of parameters such as wavelength range, bandwidth, size (circular and square wafers of 1-300mm, lenses, aspherical lenses, special-shaped wafers, etc.), and number of coating layers. It can also provide special specification products such as ultra-narrowband and high channel isolation, meeting the stringent application requirements of high-end fields such as scientific research, industry, and medical care, and providing core optical support for high-precision infrared detection and imaging systems.
