660DF50 25 mm Dia. Protected Coating; Bandpass Filter Protected Coating
The 660DF50 is a Bandpass Filter with a circular shape and a diameter of 25 mm, sourced from the reputable vendor, Omega Optical. This filter is designed to transmit light within a specific range of wavelengths, while blocking other wavelengths, making it an essential component in various optical systems.
The filter's central wavelength (CWL) is 660 nm, and it has a cut-on wavelength of 635 nm and a cut-off wavelength of 685 nm. This means it allows the transmission of light around the 660 nm wavelength while blocking light on either side of this range. This precise wavelength selection makes the 660DF50 ideal for applications requiring narrowband filtering.
The filter is constructed with a Material ID of UVFS MAL-1965, and it has a thickness of 3.5 mm. The front and back of the filter are coated with "ome 660df50", a protected coating that enhances the filter's durability and performance. The filter's shape is defined as a Thin Lens, further optimizing its optical properties.
