554FDN12 12.5 mm Dia. Bandblocking Dichroic Filter 554nm
The 554FDN12 is a high-quality Dichroic Filter, specifically designed for bandblocking applications, available from Knight Optical. This filter boasts a 12.5 mm diameter and a thickness of 1.1 mm, making it a versatile and compact solution for various optical systems.
The filter is designed to cut on at 639 nm and cut off at 470 nm, with a central wavelength (CWL) of 554 nm. This specific wavelength makes it ideal for applications that require precise filtering in the yellow-green region of the spectrum. The filter's coating, both on the front and back, is identified as 'kni 554fdn-0', further ensuring its performance and durability.
The 554FDN12 is made from n-bk7 Schott, a high-quality optical glass known for its excellent transmission properties and low auto-fluorescence. This material choice contributes to the filter's overall performance and reliability.
The filter is shaped as a thin lens, which is beneficial for applications that require minimal thickness or where space is a constraint. It is currently in stock and available for immediate purchase through Knight Optical's website.
