65-668 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 880nm
The 65-668 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by a 12.5 mm diameter and a thickness of 7.5 mm, making it a robust and stable option for various optical applications.
The filter's primary function is to allow light in a specific wavelength range to pass through while blocking out other wavelengths. In this case, the central wavelength (CWL) is 880 nm, with a full width at half maximum (FWHM) of 10 nm. This means the filter is designed to transmit light most efficiently at 880 nm, with a tolerance range of 875 nm to 885 nm.
The 65-668 filter features a thin lens shape, which can be beneficial in certain optical systems. The front and back surfaces of the filter are coated with the EDM 65-668 coating, which likely contributes to its bandpass characteristics.
This filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. The catalog number for this item is 65-668, making it easy to reference and order.
