63-410 25 mm Dia. Non-Reflective Neutral Density Filter; OD 1 NIR 700-1200nm

The 63-410 is a 25 mm diameter Non-Reflective Neutral Density Filter, specifically designed for use in the near-infrared (NIR) spectrum, between 700 and 1200nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is identified by the catalog number 63-410.

The filter is of the Neutral Density type, which means it reduces the intensity of all wavelengths of light equally, providing a uniform attenuation. This is particularly useful in applications where a specific light level needs to be maintained across the entire spectrum. The Neutral Density Filter has an Optical Density (OD) of 1, which translates to a 10-fold reduction in light intensity.

The filter is constructed with a Circular base shape, making it compatible with various optical systems. It is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties and durability. The filter has a thickness of 1.5mm, which contributes to its robustness and stability.

The filter's front and back surfaces are coated with EDM 63-400, a non-reflective coating that reduces surface reflections, thereby improving transmission and reducing unwanted glare. The filter's geometry is defined by a Thin Lens shape, which is often used in optical systems to minimize aberrations and distortions.
