FBH660-10 Premium Bandpass Filter; Dia:25 mm; CWL=660nm; FWHM=10nm
The FBH660-10 Premium Bandpass Filter is a high-quality optical component designed for precise wavelength selection, manufactured by Thorlabs. This filter is circular in shape with a diameter of 25 mm and a thickness of 2 mm, making it suitable for a wide range of optical applications.
The filter is specifically designed for a central wavelength (CWL) of 660 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows light within a narrow band around 660 nm to pass through while blocking out other wavelengths. The cut-on wavelength is 655 nm, and the cut-off wavelength is 665 nm, further enhancing its wavelength selectivity.
The FBH660-10 filter features a thin lens shape and is made from UVFS material, identified as MAL-1965 in the catalog. The front and back surfaces of the filter are coated with Thorlabs' proprietary coating, denoted as "tho fbh660-10", which enhances its performance and durability.
According to the vendor's website, this item is currently in stock, and the link provided leads directly to the product page for easy access and purchase. This filter is a reliable choice for applications requiring narrowband wavelength selection in the red region of the spectrum.
