65-653 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 640nm
The 65-653 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable optical vendor, Edmund Optics. This filter is designed to transmit light within a specific range of wavelengths, making it an essential component in various optical systems.
The filter's primary wavelength is 640nm, with a Full Width at Half Maximum (FWHM) of 10nm. This means it allows light closest to this wavelength to pass through while blocking out other wavelengths. The cut-on wavelength is 635nm, and the cut-off wavelength is 645nm, further illustrating its narrowband transmission properties.
The 65-653 filter is mounted, providing a convenient and secure method of integration into optical systems. It has a thickness of 7.5mm, contributing to its durability and stability. The filter's material ID is UVFS MAL-1965, a detail that may be crucial for material compatibility in certain applications.
The front and back of the filter are coated with EDMP 65-653, a coating that likely enhances the filter's performance and longevity. The filter's shape is that of a Thin Lens, suggesting it may have focusing or diverging properties, although this is not explicitly stated in the provided data.
