The 47-585 is a 25 mm diameter Shortpass Filter with an OD of 2.0, manufactured by Edmund Optics. This filter features a traditional coating on both the front and back surfaces, specifically the EDM 47-817 coating. The filter's primary function is to transmit wavelengths shorter than 750nm while blocking longer wavelengths, making it ideal for applications that require the removal of infrared light.
The filter's geometry includes a diameter of 25 mm and a thickness of 3 mm, providing a robust and compact design. The cut-on wavelength is 0 nm, and the cut-off wavelength is 750 nm, indicating a sharp transition between transmitted and blocked wavelengths. The filter's shape is thin lens, which is beneficial for applications that require minimal added thickness or weight.
This filter is part of the UVFS MAL-1965 material ID family, which is known for its high-quality optical properties. The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
