550FDN12 12.5 mm Dia. Bandblocking Dichroic Filter 550nm

The 550FDN12 is a high-quality Dichroic Filter, sourced from Knight Optical, a leading vendor in the optical industry. This filter is specifically designed for bandblocking applications, with a central wavelength of 550nm. It is circular in shape, featuring a diameter of 12.5mm and a thickness of 1.1mm, making it a versatile option for various optical setups.

The filter is made from N-BK7 Schott, a renowned optical glass known for its excellent optical properties. The front and back of the filter are coated with KNI 550FDN-0, a specialized coating that enhances the filter's performance and durability.

The 550FDN12 has a cut-on wavelength of 630nm and a cut-off wavelength of 470nm, making it highly effective at blocking unwanted wavelengths while allowing the desired 550nm light to pass through. This is particularly useful in applications such as fluorescence microscopy, spectroscopy, and other scenarios where specific wavelength control is required.

The filter is currently in stock and available for immediate purchase through the vendor's website. For more information, please refer to the provided weblink.
