MFND-52-92 52 mm Dia. Mounted N-BK7 Visible Reflective Neutral Density Filter; t=2mm 400-700nm

The MFND-52-92 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 renowned 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.

The filter is mounted and has a base shape of a circle, with a diameter of 52mm and a thickness of 2mm. This makes it compatible with a wide range of optical systems that require neutral density filters of this size. The filter is made from N-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence.

The MFND-52-92 is coated with Opt FND-92 on both the front and back surfaces. This coating is a reflective neutral density filter, designed to reduce the intensity of light without altering its color balance. The coating is thin, allowing it to be used in systems where space is a limiting factor.

In terms of geometry, the filter is shaped as a thin lens, which is ideal for applications where minimal distortion and high clarity are required. This filter is a versatile and high-performance option for those requiring a neutral density filter in the visible light spectrum.
