64-358 50 mm Dia. Infrared (IR) Neutral Density Filter; OD 0.3 2-14µm
The 64-358 is a 50 mm diameter Infrared (IR) Neutral Density Filter, specifically designed for use in the infrared spectrum with an Optical Density (OD) of 0.3, covering a wavelength range of 2-14µm. This filter is sourced from the reputable optical vendor, Edmund Optics, and is available for purchase through their website.
The filter is a Circular type, made from Germanium Burnett material, a common choice for infrared applications due to its high transmittance in the infrared region. The filter's geometry includes a diameter of 50 mm and a thickness of 1 mm, making it suitable for a wide range of optical systems.
The 64-358 filter features a Thin Lens shape, which helps to minimize optical aberrations and distortions, thereby enhancing the overall performance of the optical system. The front and back surfaces of the filter are coated with 'edm 12-003', a coating type that further optimizes the filter's performance in the infrared spectrum.
