67-840 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 720nm
The 67-840 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 that require the isolation of specific spectral regions.
The filter's primary wavelength is 720nm, with a full width at half maximum (FWHM) of 10nm. The cut-on wavelength is 715nm, and the cut-off wavelength is 725nm, indicating a narrow and precise transmission band. The filter's thickness is 5.9mm, providing sufficient structural integrity for various applications.
The 67-840 features a coating on both the front and back surfaces, specifically the EDM 67-773 coating. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency. The filter's shape is classified as a Thin Lens, further enhancing its functionality in optical systems.
The filter is currently in stock and available for purchase through the provided weblink. Detailed product information, including technical specifications and purchasing options, can be found on the vendor's website.
