16-071 25 mm Diameter SCHOTT NG3 Precision Absorptive Neutral Density Filter; OD 2.5 450-700nm

The 16-071 is a 25 mm diameter Neutral Density Filter, precision engineered by Edmund Optics using SCHOTT NG3 material. This filter is designed to provide a uniform attenuation of light across the visible spectrum, specifically within the 450-700nm range.

The filter boasts an Optical Density (OD) of 2.5, which translates to a transmission of approximately 0.63%. This makes it an ideal choice for applications that require a significant reduction in light intensity, such as high-powered laser applications or high-exposure imaging scenarios.

The SCHOTT NG3 material is known for its excellent optical properties, including high transmittance, low auto-fluorescence, and excellent thermal stability. The filter is shaped as a thin lens, with a thickness of 2.44mm, providing a balance between optical performance and mechanical robustness.

The front and back surfaces of the filter are coated with the EDM 16-071 coating, which further enhances its performance by reducing surface reflections and improving overall light transmission. This coating also provides a measure of protection against environmental contaminants and wear and tear, contributing to the filter's longevity and reliability.
