580DIB25 25 mm Dia. Standard Interference Bandpass Filter 580nm
The 580DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to center at a wavelength of 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 circular base shape, a common design for filters due to its ease of integration into various optical systems. The filter's geometry includes a diameter of 25mm and a thickness of 6.1mm, providing a robust and compact design.
The coating on both the front and back surfaces of the filter is KNI 580DIB. This coating is specifically designed to enhance the filter's performance, ensuring high transmission rates within the passband and effective blocking of unwanted wavelengths.
The filter's shape is described as a Thin Lens, indicating its potential use in lens systems. It is currently in stock and available for immediate purchase through the vendor's website, as indicated by its weblink status.
