Collection: Infrared (IR) Bandpass Filter
An Infrared (IR) bandpass filter is designed to selectively transmit infrared light within a specific wavelength range while blocking other wavelengths outside this range. These filters are commonly used in various optical and sensing applications where precise control over the infrared spectrum is required.
Wavelength Range: IR bandpass filters typically operate in the infrared spectrum, which spans from about 3 µm to 16 µm, with some filters extending up to 20 µm depending on the design and application
Material and Coating: These filters are often made using materials like silicon (Si), germanium (Ge), sapphire, and zinc selenide (ZnSe), which are transparent in the infrared region. They also feature multilayer coatings, such as thin-film Fabry-Pérot structures, to achieve their filtering properties
