The 15-451 is a specialized optical filter developed by Edmund Optics, designed primarily for applications requiring longpass filtering at the 780nm wavelength. This filter boasts a 12.7mm diameter and a thickness of 1.1mm, making it a versatile choice for various optical systems.
The filter is constructed from UVFS Mal-1965, a unique material that contributes to its optical properties. It is designed to cut on at 780nm, allowing wavelengths longer than this to pass through while blocking shorter wavelengths. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths shorter than 780nm.
The 15-451 features a dielectric coating on both the front and back surfaces. This coating enhances the filter's performance and durability, providing improved transmission and resistance to environmental factors. The filter's shape is that of a thin lens, further expanding its potential applications.
The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. For more detailed information or to make a purchase, users can follow the provided weblink.
