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.
