FB5500-500 Dia. 1 in IR Bandpass Filter; CWL=5.50 µm; FWHM=500nm

The FB5500-500 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 (25.4 mm) and a thickness of 3 units, making it compatible with a wide range of optical systems.

The filter is constructed from Germanium Burnett, a material known for its excellent optical properties. It is specifically designed to transmit light in the infrared (IR) spectrum, with a central wavelength (CWL) of 5.50 µm and a full width at half maximum (FWHM) of 500nm. This precise wavelength range ensures optimal performance in specific applications.

The FB5500-500 features a thin lens shape, with anti-reflection coatings on both the front and back surfaces. These coatings, denoted as 'tho fb5500-500', are designed to reduce surface reflections and increase transmission, thereby enhancing the overall efficiency of the optical system.

The filter's physical data includes a cut-on wavelength of 5250 and a cut-off wavelength of 5750. This means that it begins to transmit light at 5250nm and stops transmitting at 5750nm, making it highly selective and effective in its function.
