47-586 25 mm Dia. Traditional Coated OD 2.0 Shortpass Filter; t=3mm 800nm

The 47-586 is a 25 mm diameter Shortpass Filter with an OD 2.0 and a thickness of 3mm, designed for use in optical systems that require the blocking of specific wavelengths while allowing others to pass through. This filter, sourced from Edmund Optics, is a part of their extensive catalog and is available for purchase directly from their website.

The Shortpass Filter type is characterized by its ability to transmit wavelengths shorter than a specified value while blocking longer wavelengths. In this case, the 47-586 model has a cut-off wavelength of 800nm, meaning it will allow the passage of light with wavelengths shorter than 800nm and block light with wavelengths longer than 800nm. This makes it an ideal choice for applications where the control of specific wavelengths is crucial.

The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. It features a Thin Lens shape, which is designed to minimize optical aberrations and distortions, further enhancing its performance in optical systems.

The 47-586 model is coated with EDM 47-818 on both the front and back surfaces, which provides additional protection and enhances its performance in specific applications. The coating also helps to reduce reflections and increase transmission, making the filter more efficient in blocking the specified wavelengths.
