554FDN50 50 x 50 mm Bandblocking Dichroic Filter 554nm
The 554FDN50 is a Bandblocking Dichroic Filter, measuring 50 x 50 mm, manufactured by Knight Optical. This filter is designed to block light in the 470-639nm range while allowing light at the center wavelength (CWL) of 554nm to pass through.
The filter is made from N-BK7 Schott, a popular optical glass due to its excellent homogeneity, low auto-fluorescence, and high damage threshold. The filter's geometry includes a thickness of 1.1mm, making it suitable for various optical applications.
The coating on both the front and back of the filter is KNI 554FDN-0, a proprietary coating by Knight Optical. This coating enhances the filter's performance, ensuring efficient blockage of unwanted wavelengths and transmission of the desired 554nm light.
The filter is rectangular in shape, specifically a Thin Lens shape, which is often used in optical systems where a flat surface is required. The filter's current status is in stock, and more information can be found on Knight Optical's website through the provided weblink.
