550FDL25 25 mm Dia. Longpass Dichroic Filter 550nm by Knight Optical

The 550FDL25 is a high-quality Dichroic Filter, specifically a Longpass Filter with a 550nm cut-on wavelength, manufactured by Knight Optical. This filter is designed with a circular geometry, featuring a 25mm diameter 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 chemical durability. The filter's coating, KNI 550FDL-0, is applied to both the front and back surfaces, enhancing its performance and ensuring efficient light transmission.

The 550FDL25 is a Longpass Filter, meaning it allows light of longer wavelengths to pass through while blocking or reflecting shorter wavelengths. The cut-on wavelength of 550nm indicates that this filter begins to transmit light at this wavelength, making it ideal for applications where the differentiation of longer wavelengths is crucial.

This filter is currently in stock and available for immediate purchase through the vendor's website. Detailed specifications, including the cut-on wavelength and geometry, can be found on the product page, providing users with all the necessary information for their selection process.
