64-356 25 mm Dia. Infrared (IR) Neutral Density Filter; OD 2 2-14µm
The 64-356 is a 25 mm diameter Infrared (IR) Neutral Density Filter, offered by the renowned optical components vendor, Edmund Optics. This filter is designed with a base shape of a circle and constructed from Germanium Burnett material, ensuring high-quality performance and durability.
The filter's primary function is to reduce the intensity of incident light without altering its color composition. This is achieved through the application of a specialized coating, denoted as 'edm 12-015', on both the front and back surfaces. This coating provides an Optical Density (OD) of 2, specifically designed for the wavelength of 588 nm.
The geometry of this filter includes a diameter of 25 mm and a thickness of 1 mm, classifying it as a Thin Lens. The 'Thin Lens' classification suggests that the filter is thin relative to its diameter, which can be advantageous in certain optical system designs.
The filter's current status is 'in stock', and it is available for purchase through the vendor's website, with the weblink provided in the item data for convenience. This filter is a reliable choice for applications that require IR light reduction while maintaining color neutrality.
