64-362 50 mm Dia. Infrared (IR) Neutral Density Filter; OD 3 2-14µm

The 64-362 is a 50 mm diameter Infrared (IR) Neutral Density Filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for use in the infrared spectrum, with a wavelength of 588 nm, making it ideal for applications that require precise control over infrared light.

The filter is constructed with a base shape of a circle, a common design for optical components due to its symmetry and ease of integration into various systems. The material used for this filter is Germanium Burnett, a high-quality, durable material known for its excellent optical properties.

The filter features a coating on both the front and back surfaces, specifically the EDM 12-017 coating. This coating is designed to enhance the filter's performance and durability, providing reliable operation even in challenging environments.

The geometry of the filter includes a diameter of 50 mm and a thickness of 1 mm. This thin design helps minimize the impact of the filter on the overall optical path, making it suitable for use in compact systems.

The filter is classified as a Neutral Density Filter, which means it reduces the intensity of light without altering its color. The specific density of this filter is OD 3, which corresponds to a reduction of 99.9% of the incident light. The filter is designed to operate over a wide range of wavelengths, from 2 to 14 µm, making it a versatile choice for many infrared applications.
