MFND-25-92 25 mm Dia. Mounted N-BK7 Visible Reflective Neutral Density Filter; t=2mm 400-700nm
The MFND-25-92 is a Neutral Density Filter, specifically designed for use in the visible light spectrum, with a wavelength of 550nm. This filter is manufactured by OptoSigma, a leading vendor in the optical industry, and is available for purchase on their official website. The filter is currently in stock, as indicated by its weblink status.
This filter is mounted and features a circular geometry with a diameter of 25mm and a thickness of 2mm. It is made from N-BK7, a high-quality glass manufactured by Schott, which is known for its excellent optical properties. The filter is coated on both the front and back with Opt FND-92, a reflective neutral density coating that is specifically designed for use in the visible light spectrum, between 400-700nm.
The shape of the filter is thin lens, which is designed to minimize optical aberrations and distortions. This makes it an ideal choice for applications that require high precision and accuracy, such as scientific research, photography, and optical instrumentation.
