63-403 12.5 mm Dia. Non-Reflective Neutral Density Filter; OD 2 NIR 700-1200nm

The 63-403 Neutral Density Filter is a high-quality optical component designed for applications that require precise control over light intensity. Manufactured by Edmund Optics, this filter boasts a circular shape with a diameter of 12.5 mm and a thickness of 1.5 mm, making it suitable for use in compact optical systems.

This filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It is coated on both the front and back surfaces with the EDM 63-403 coating, which provides excellent neutral density performance. The coating is non-reflective, further enhancing the filter's performance by minimizing unwanted reflections.

The 63-403 filter is designed to attenuate light uniformly across the near-infrared (NIR) spectrum, specifically between 700nm and 1200nm. This makes it ideal for use in applications where control over NIR light is necessary, such as in biomedical imaging, laser applications, or astronomical observations.

The filter's geometry and coating are designed to mimic a thin lens, ensuring minimal distortion of the light passing through it. This feature, combined with its high-quality construction, makes the 63-403 filter a reliable and versatile choice for a wide range of optical applications.
