530FDN12 12.5 mm Dia. Bandblocking Dichroic Filter 530nm
The 530FDN12 is a Dichroic Filter, specifically designed for bandblocking applications, with a diameter of 12.5 mm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components. The filter's primary function is to block light in the 447-611 nm range while allowing light at the center wavelength (CWL) of 530 nm to pass through.
This filter is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The filter's geometry includes a thickness of 1.1 mm, which contributes to its durability and overall performance. The coating on both the front and back surfaces of the filter is 'kni 530fdn-0', a proprietary coating developed by Knight Optical for optimal bandblocking performance.
The 530FDN12 filter is designed in the shape of a thin lens, which can be beneficial in certain optical system configurations. The cut-on wavelength is 611 nm, and the cut-off wavelength is 447 nm, providing a precise range for light blocking. This filter is currently in stock and available for immediate purchase through the vendor's website.
