MFND-30-70 30 mm Dia. Mounted N-BK7 Visible Reflective Neutral Density Filter; t=2mm 400-700nm

The MFND-30-70 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 catalog number for this product is MFND-30-70.

This filter is mounted and has a diameter of 30mm, making it suitable for a wide range of optical applications. The thickness of the filter is 2mm, which is thin enough to minimize optical aberrations while still providing robust protection for your optical system.

The filter is made from N-BK7, a high-quality glass material produced by Schott. This material is known for its excellent optical properties, including high transparency and low auto-fluorescence, making it an ideal choice for demanding optical applications.

The front and back surfaces of the filter are coated with Opt FND-70, a reflective neutral density coating. This coating is designed to reduce the intensity of light passing through the filter without altering its color balance. This is particularly useful in high-intensity lighting environments where excessive light could potentially damage your optical system or cause unwanted exposure.

The shape of the filter is thin lens, which is designed to minimize optical distortions and ensure the highest possible image quality. This filter is currently in stock and available for immediate purchase on the OptoSigma website.
