MFND-25-50 25 mm Dia. Mounted N-BK7 Visible Reflective Neutral Density Filter; t=2mm 400-700nm
The MFND-25-50 is a Neutral Density Filter, specifically designed for visible light applications, with a diameter of 25 mm and a thickness of 2 mm. This filter is mounted and features a reflective coating on both the front and back surfaces, identified as 'opt fnd-50'.
The filter is made of N-BK7, a high-quality borosilicate glass manufactured by Schott, known for its excellent optical properties and durability. The N-BK7 material ensures high transmission and low absorption across the visible spectrum, making it ideal for a wide range of applications.
The MFND-25-50 filter is designed to operate at a central wavelength of 550 nm, which falls within the green region of the visible spectrum. This makes it suitable for use in applications where green light needs to be attenuated or balanced with other colors.
The filter is sourced from OptoSigma, a leading vendor in the optical industry, ensuring high quality and reliability. The vendor's website indicates that the filter is currently in stock, making it readily available for immediate use.
