63-378 12.5 mm Dia. Non-Reflective Neutral Density Filter; OD 0.6 NIR 400-700nm

The 63-378 is a Neutral Density Filter with a diameter of 12.5 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is designed to reduce the intensity of light without altering its color composition, making it an ideal choice for various applications where control over light intensity is crucial.

The filter boasts a non-reflective coating on both the front and back surfaces, which significantly minimizes surface reflections, thereby enhancing transmission and image quality. This non-reflective coating also aids in reducing ghosting and flare effects, which are common issues in high-intensity lighting scenarios.

The 63-378 filter has an Optical Density (OD) of 0.6, which translates to a reduction of approximately 60% of the incident light. This level of density is suitable for moderate light reduction tasks, offering a good balance between light control and maintaining sufficient light for imaging.

The filter is constructed from UVFS Mal-1965 material, a high-quality optical material known for its excellent transmittance and durability. The filter's geometry includes a thickness of 1.5 mm, which contributes to its robustness and resistance to deformation.

The filter's wavelength of 588 nm indicates its primary operational range. However, it is important to note that this filter is designed to transmit light within the Near-Infrared (NIR) spectrum, specifically between 400 and 700 nm. This makes it suitable for applications that require NIR light transmission.
