63-393 25 mm Dia. Non-Reflective Neutral Density Filter; OD 2 NIR 400-700nm

The 63-393 is a Neutral Density Filter with a 25 mm diameter, sourced from the renowned optical vendor, Edmund Optics. This filter is designed to reduce light intensity without altering the color composition of the incident light, making it an ideal choice for various applications where control over light intensity is crucial.

The filter features a non-reflective coating, which minimizes surface reflections, thereby enhancing transmission and reducing ghosting and flare effects. This coating is applied on both the front and back surfaces, ensuring optimal performance from both directions.

The 63-393 filter is constructed from UVFS Mal-1965 material, a robust and reliable option in the field of optical filters. It has a thickness of 1.5 mm, which contributes to its durability and resistance to mechanical stress.

This filter is designed for use with visible light, with a central wavelength of 588 nm. It is particularly effective in the 400-700 nm Near-Infrared (NIR) range, making it suitable for a wide range of applications in this spectrum.

The filter is shaped as a Thin Lens, a design that minimizes optical aberrations and distortions, ensuring high-quality imaging and light transmission. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its 'Valid - in stock' weblink status.
