65-665 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 830nm

The 65-665 is a Bandpass Filter, specifically designed and manufactured by Edmund Optics. This filter is circular in shape, with a diameter of 12.5 mm and a thickness of 7.5 mm, making it suitable for a wide range of optical applications. The filter is mounted, providing ease of use and integration into existing systems.

The filter is designed to operate at a central wavelength of 830 nm, with a full width at half maximum (FWHM) of 10 nm. This specificity makes it ideal for applications that require precise wavelength selection and rejection of unwanted spectral regions. The cut-on wavelength is 825 nm, and the cut-off wavelength is 835 nm, further enhancing its spectral performance.

The 65-665 features a traditional coating on both the front and back surfaces. This coating is specifically designed and optimized for the filter's intended use, providing excellent transmission and blocking characteristics. The coating also enhances the filter's durability and resistance to environmental factors, ensuring reliable performance over time.

The filter's shape is that of a Thin Lens, which can be beneficial in certain optical configurations. This shape, combined with its other properties, makes the 65-665 a versatile and high-performing optical element.
