FB5000-500 Dia. 1 in IR Bandpass Filter; CWL=5.00 µm; FWHM=500nm
The FB5000-500 is a high-quality Bandpass Filter, sourced from the renowned optical component manufacturer, Thorlabs. This filter is designed with a circular base shape, featuring a diameter of 1 inch and a thickness of 2 units, making it compatible with a wide range of optical systems.
The filter is made from Germanium Burnett, a material known for its excellent optical properties, ensuring high-performance and reliability. The FB5000-500 is specifically designed to pass wavelengths in the infrared region, with a central wavelength (CWL) of 5.00 µm. This makes it ideal for applications that require the isolation of specific infrared wavelengths.
The filter's physical data includes a cut-on wavelength of 4750 and a cut-off wavelength of 5250, providing a full width at half maximum (FWHM) of 500nm. This ensures a tight spectral bandwidth, reducing unwanted noise and increasing signal clarity.
The FB5000-500 features a Thin Lens shape, with coatings on both the front and back surfaces. These coatings, denoted as 'tho fb5000-500', are designed to enhance the filter's performance and durability, providing excellent transmission and blocking characteristics.
The filter is currently in stock and available for immediate purchase through the Thorlabs website, as indicated by its weblink status. For more information, users can visit the provided weblink.
