The 570DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to center at 570nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the cut-on wavelength is 565nm, and the cut-off wavelength is 575nm, making it highly effective in isolating the 570nm wavelength.
The filter is made from UVFS Mal-1965, a material known for its optical properties and durability. It has a thickness of 6.1mm, providing sufficient structural integrity for most applications.
The coating on both the front and back surfaces of the filter is KNI 570DIB, a specialized coating that enhances the filter's performance and durability. The filter's shape is a Thin Lens, which is suitable for a wide range of optical systems.
