62-677 50 mm Dia. NIR Metallic Based Neutral Density Filter; OD 1.3 700-1100nm

The 62-677 is a Neutral Density Filter with a 50 mm diameter, sourced from the renowned optical vendor, Edmund Optics. This filter is specifically designed for use in the Near-Infrared (NIR) spectrum, with an operational wavelength of 588 nm.

The filter boasts a Metallic Based Neutral Density coating on both the front and back surfaces, identified by the coating code "edm 47-828". This coating is responsible for the filter's Optical Density (OD) of 1.3, which is equivalent to a transmission of approximately 5%. This makes the filter particularly useful in applications where a significant reduction in light intensity is required, such as high-powered laser systems or intense astronomical observations.

The filter's geometry is another notable feature. It has a thickness of 5 mm, which is relatively thin compared to other optical elements. This thinness, combined with its circular shape, contributes to the filter's ease of integration into various optical systems. The filter's shape is classified as "Thin Lens", indicating that it is designed to minimize optical aberrations and distortions, further enhancing its utility in precision optical applications.
