65-788 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 1300nm
The 65-788 is a 25 mm diameter mounted bandpass interference filter, designed for optimal performance at a central wavelength of 1300nm. This filter, sourced from Edmund Optics, is a crucial component for applications requiring precise wavelength selection and rejection of unwanted spectral regions.
The filter boasts a full width at half maximum (FWHM) of 12nm, ensuring a narrow and specific passband. This characteristic is particularly beneficial in applications such as fluorescence microscopy, spectroscopy, and optical telecommunications, where precise wavelength control is paramount.
The filter's geometry includes a diameter of 25mm and a thickness of 7.5mm, providing sufficient structural integrity for most applications. The filter's thin lens shape further enhances its optical performance, ensuring minimal distortion and optimal light transmission.
The 65-788 filter features a traditional coating on both the front and back surfaces, enhancing its durability and resistance to environmental factors. This coating also aids in reducing surface reflections, thereby improving the filter's overall efficiency.
The filter's physical data includes a cut-on wavelength of 1294nm and a cut-off wavelength of 1306nm. This narrow range further emphasizes the filter's ability to precisely control the passing wavelengths.
