The MFND-52-50 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 renowned vendor in the optical industry, and is available for purchase through their official website. The filter is currently in stock, as indicated by its weblink status.
The MFND-52-50 features a circular geometry with a diameter of 52mm and a thickness of 2mm. It is made from N-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This material ensures the filter's durability and reliability in various optical applications.
The filter is coated with Opt FND-50 on both the front and back surfaces. This coating enhances the filter's performance by reducing unwanted reflections and increasing its overall neutrality. The coating also provides a thin lens shape, minimizing the filter's impact on the overall optical system's design and performance.
