520FDS12 12.5 mm Dia. Shortpass Dichroic Filter 520nm
The 520FDS12 is a high-quality dichroic filter, 12.5 mm in diameter, designed for shortpass applications with a cutoff wavelength of 520nm. This filter is sourced from Knight Optical, a renowned vendor known for their extensive catalog of optical elements.
The filter is made of n-BK7 Schott, a durable and optical-quality glass, and has a thickness of 1.1mm. It features a thin lens shape, which is ideal for applications where space is a constraint. The filter's coating, kni 520fds-0, is applied on both the front and back surfaces, ensuring optimal performance.
The 520FDS12 has a physical data specification of 746nm for the cut-on wavelength and 520nm for the cut-off wavelength. This makes it suitable for applications where light with a wavelength shorter than 520nm needs to be passed, while blocking longer wavelengths.
The filter is currently in stock and available for immediate purchase. For more information, you can visit the vendor's website through the provided weblink.
