The 67-061 is a 12.5 mm diameter dichroic filter, specifically designed for fluorescence applications with a cut-on wavelength of 685nm. This filter is sourced from the reputable optical vendor, Edmund Optics, and is available for purchase through their website.
The filter is made from UVFS material, identified as MAL-1965 in the Edmund Optics catalog. It features a circular base shape and a thin lens design, making it suitable for a wide range of optical systems. The filter has a diameter of 12.5mm and a thickness of 1.05mm, providing a compact yet effective solution for your optical needs.
The coating on both the front and back of the filter is EDm 67-061, which is specifically designed to work with the 685nm wavelength. This coating ensures high transmission and low reflection at the specified wavelength, making it ideal for fluorescence applications.
Please note that the filter is cut on 685nm and has no specified cut-off wavelength. This means that it will transmit wavelengths above 685nm, making it suitable for use with a variety of fluorescence emissions.
