580DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 580nm
The 580DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to center at 580nm. 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 575nm, and the cut-off wavelength is 585nm, making it highly effective in isolating the 580nm wavelength. The Central Wavelength (CWL) of the filter is also 580nm, ensuring optimal performance for its intended use.
The filter is made from UVFS Mal- 1965, a material known for its excellent optical properties. It has a Thin Lens shape, which is beneficial for applications that require minimal added thickness or weight. The geometry of the filter includes a diameter of 12.5mm and a thickness of 6.1mm, making it suitable for a wide range of optical systems.
The coating on both the front and back of the filter is KNI 580DIB. This coating is specifically designed to enhance the filter's performance and durability, ensuring reliable and consistent operation.
