552FDN25 25 mm Dia. Bandblocking Dichroic Filter 552nm

The 552FDN25 is a Dichroic Filter, specifically designed for bandblocking applications, with a diameter of 25 mm. This filter, available from Knight Optical, is a versatile component in the realm of optical systems, ideal for applications that require the selective blocking of specific wavelength ranges.

The filter's primary function is to block wavelengths between 459nm and 645nm, while allowing the central wavelength of 552nm to pass through. This characteristic makes it an excellent choice for applications that necessitate the isolation of this particular wavelength range.

The 552FDN25 is crafted from N-BK7 Schott, a widely used optical glass known for its excellent optical properties and durability. The filter's geometry includes a thickness of 1.1mm, providing a balance between robustness and compactness.

The coating on both the front and back surfaces of the filter is 'kni 552fdn-0', a proprietary coating developed by Knight Optical. This coating enhances the filter's performance, ensuring efficient blockage of unwanted wavelengths and optimal transmission of the desired 552nm wavelength.

In terms of shape, the 552FDN25 is a Thin Lens, a design that minimizes optical aberrations and ensures optimal light transmission. This feature makes it a suitable choice for precision optical systems.

The 552FDN25 is currently in stock and available for immediate purchase from Knight Optical's website. With its robust design, specific wavelength blocking capabilities, and high-quality coating, this filter is an excellent addition to any optical system requiring bandblocking functionality.
