FB2300-50 Dia. 25 mm IR Bandpass Filter; CWL=2.30 µm; FWHM=50nm
The FB2300-50 is a high-quality Bandpass Filter, sourced from the renowned optical component manufacturer, Thorlabs. This filter is designed with a center wavelength (CWL) of 2.30 µm and a full width at half maximum (FWHM) of 50nm, making it ideal for applications that require precise wavelength selection in the infrared spectrum.
The filter is circular in shape, with a diameter of 25 mm and a thickness of 1 mm, ensuring efficient light transmission and minimal optical loss. It is made from high-quality n-BK7 Schott glass, a material known for its excellent optical properties and durability.
The FB2300-50 is coated with a proprietary coating on both the front and back surfaces, labeled as 'tho fb2300-50'. This coating enhances the filter's performance by reducing reflection and increasing transmission in the desired wavelength range. The cut-on wavelength is 2275 nm, and the cut-off wavelength is 2325 nm, providing a narrow and precise passband.
This filter is currently in stock and available for immediate purchase through the Thorlabs website, as indicated by its weblink status. The catalog number for this item is FB2300-50.
