49-068 12.5 mm Dia. NIR Metallic Based Neutral Density Filter; OD 0.9 700-1100nm
The 49-068 is a Neutral Density Filter with a 12.5 mm diameter, sourced from the reputable optical vendor, Edmund Optics. This filter is specifically designed for use in the Near-Infrared (NIR) spectrum, with a wavelength of 588nm.
The filter boasts a Metallic Based coating on both the front and back surfaces, denoted as 'edm 49-068'. This coating is responsible for the filter's primary function, which is to reduce the intensity of light passing through it without altering the color composition. The Optical Density (OD) of this filter is 0.9, indicating a reduction of approximately 80% of the incident light.
The filter's geometry is another notable feature. It has a thickness of 1.5mm and a base shape of a circle, making it compatible with a wide range of optical systems. The filter is designed in a Thin Lens shape, which helps to minimize optical aberrations and distortions.
The catalog number for this filter is 49-068, and it is currently in stock, as indicated by its weblink status. For more information, users can visit the provided weblink: "https://www.edmundoptics.com/p/09-od-125mm-dia-nir-nd-filter-/9423/".
