67-855 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 870nm
The 67-855 is a Bandpass Filter with a circular base shape and a 25 mm mounted diameter, sourced from the reputable vendor Edmund Optics. This filter is designed to transmit light within a specific range of wavelengths, while blocking other wavelengths, making it ideal for applications requiring wavelength selectivity.
The filter's primary wavelength is 870 nm, with a full width at half maximum (FWHM) of 10 nm. The FWHM is a measure of the filter's bandwidth, indicating the range of wavelengths it can transmit around the central wavelength. This model has a cut-on wavelength of 865 nm and a cut-off wavelength of 875 nm, ensuring a narrow and precise transmission band.
The filter is constructed with a thickness of 5.9 mm and is coated with EDM 67-788 on both the front and back surfaces. This coating enhances the filter's performance and durability, providing excellent optical properties and resistance to environmental factors.
The 67-855 filter features a Thin Lens shape, which is beneficial for applications requiring minimal optical path deviation. It is currently in stock and available for immediate purchase through the provided weblink.
