590FDL25 25 mm Dia. Longpass Dichroic Filter 590nm

The 590FDL25 is a Dichroic Filter, specifically designed for longpass applications with a cut-on wavelength of 590nm. This filter is sourced from Knight Optical, a renowned vendor known for their high-quality optical components. The filter is designed with a circular geometry, featuring a diameter of 25mm and a thickness of 1.1mm, making it suitable for a wide range of optical applications.

The filter is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high damage threshold. The coating on both the front and back of the filter is KNI 590FDL-0, which is specifically designed to enhance the filter's performance for longpass applications at 590nm.

The physical data of the filter indicates that it cuts off all wavelengths below 0nm, ensuring that only the desired wavelengths and above are passed through. The filter is designed in the shape of a thin lens, which can be beneficial in certain optical systems where thin, lightweight components are preferred.

The filter is currently in stock and available for purchase on Knight Optical's website. For more information, you can visit the following link: https://www.knightoptical.com/stock/default/dichroic-filter-longpass-590nm-dia-25mm.html
