63-386 25 mm Dia. Non-Reflective Neutral Density Filter; OD 0.3 NIR 400-700nm

The 63-386 is a Neutral Density Filter with a 25 mm diameter, sourced from the renowned optical components vendor, Edmund Optics. This filter is specifically designed for use in the visible spectrum, with a central wavelength of 588 nm, making it suitable for a wide range of optical applications.

The filter boasts a non-reflective coating, which significantly reduces surface reflections, thereby minimizing stray light and enhancing overall system performance. The coating is applied to both the front and back surfaces, ensuring consistent performance from both sides. This feature also makes the filter suitable for use in beam splitter applications.

The 63-386 filter is fabricated from UVFS MAL-1965, a material known for its excellent optical properties. The filter has a thickness of 1.5 mm, which contributes to its robustness and durability. The geometry of the filter is in the form of a thin lens, further enhancing its versatility in various optical setups.

The filter's Neutral Density (ND) value is 0.3, which corresponds to a transmission of 50%. This makes it ideal for applications where light intensity needs to be reduced without altering the color balance of the light. The ND filter operates within the Near-Infrared (NIR) spectrum, specifically between 400 and 700 nm, making it suitable for use in both visible and NIR light applications.

The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its robust design, versatile geometry, and high-quality coating, the 63-386 Neutral Density Filter is an excellent choice for a wide range of optical applications.
