65-793 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 1550nm
The 65-793 is a 25 mm diameter mounted bandpass interference filter, specifically designed for use at a central wavelength of 1550 nm. This filter, offered by Edmund Optics, is an essential component for applications that demand precise wavelength selection and high transmission.
The filter's bandpass characteristics are defined by its cut-on wavelength of 1544 nm and cut-off wavelength of 1556 nm, providing a full width at half maximum (FWHM) of 12 nm. This narrow bandwidth ensures minimal signal interference and high signal purity, making it ideal for applications such as optical communication, sensing, and spectroscopy.
The 65-793 features a circular geometry, with a thickness of 7.5 mm, allowing for easy integration into various optical systems. The filter is constructed from UVFS material, identified as Mal-1965, ensuring durability and stability under typical operating conditions.
The filter's front and back surfaces are coated with EDM 65-779, a traditional coating that enhances its performance by reducing surface reflections and improving transmission. This coating also provides excellent environmental stability, ensuring the filter maintains its specified performance over time.
The 65-793 is available in a thin lens shape, further simplifying its integration into optical systems. This filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
