620FAP2500 25 mm Dia. Acrylic Colour Longpass Filter 620nm
The 620FAP2500 is a 25 mm diameter Acrylic Colour Longpass Filter, specifically designed with a cut-on wavelength of 620nm. This filter is sourced from Knight Optical, a reputable vendor known for its high-quality optical elements.
The filter is a Longpass type, which means it allows transmission of longer wavelengths while blocking shorter ones. In this case, it cuts off wavelengths below 620nm and allows those above, up to 2200nm, to pass through. This makes it ideal for applications where the differentiation of longer wavelengths is crucial.
The filter is made from UVFS MAL-1965, a material known for its optical properties. It features a circular shape, with a diameter of 25mm and a thickness of 1mm, making it suitable for various optical setups. The coating on both the front and back surfaces is KNI 620FAP, which contributes to its optical performance.
The 620FAP2500 is designed in a Thin Lens shape, which is beneficial for applications where a thin, lightweight optical element is required. According to the vendor's information, this item is currently in stock and available for immediate purchase.
