47-529 25 mm Dia. NIR Metallic Based Neutral Density Filter; OD 0.5 700-1100nm

The 47-529 is a Neutral Density Filter with a 25 mm diameter and a thickness of 3 mm, sourced from the reputable vendor, Edmund Optics. This filter is designed to reduce the intensity of incident light without altering its color composition, making it an ideal choice for various applications in the near-infrared (NIR) spectrum.

The filter boasts a Metallic Based coating on both the front and back surfaces, identified as EDM 47-826. This coating is specifically designed for the NIR range, providing an Optical Density (OD) of 0.5 for wavelengths between 700nm and 1100nm. This means it attenuates the incident light by a factor of 3.16, offering a significant reduction in intensity while maintaining the integrity of the light's color balance.

The 47-529 filter is shaped as a Thin Lens, which not only contributes to its compact design but also minimizes optical aberrations. This makes it a versatile component for a wide range of optical systems.
