65-779 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 1550nm
The 65-779 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow bandwidth transmission. Sourced from Edmund Optics, this filter features a circular mount with a 12.5 mm diameter and a thickness of 7.5 mm, making it suitable for a wide range of applications.
The filter is centered at a wavelength of 1550 nm, with a full width at half maximum (FWHM) of 12 nm. This precise wavelength control ensures that only the desired light frequencies are transmitted, reducing noise and improving signal clarity. The cut-on wavelength is 1544 nm, and the cut-off wavelength is 1556 nm, further enhancing the filter's selectivity.
The 65-779 filter is coated on both the front and back surfaces with EDM 65-779, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
The filter's shape is that of a Thin Lens, which is designed to minimize optical aberrations and distortions. This makes the 65-779 an ideal choice for applications requiring high-precision optical filtering.
The filter is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by its valid weblink status. With its combination of high performance, precision, and versatility, the 65-779 is an excellent choice for a wide range of optical applications.
