47-830 12.5 mm Dia. NIR Metallic Based Neutral Density Filter; OD 2 700-1100nm

The 47-830 is a Neutral Density Filter with a 12.5 mm diameter, sourced from the renowned optical components vendor, Edmund Optics. This filter is specifically designed for use in the Near-Infrared (NIR) spectrum, with a wavelength of 588 nm.

The filter boasts a Metallic Based coating on both the front and back surfaces, identified as 'edm 47-830'. This coating is instrumental in achieving an Optical Density (OD) of 2 within the 700-1100 nm wavelength range. The OD value is a logarithmic measure of the reduction in transmittance of light, meaning this filter reduces the transmitted light by a factor of 100.

In terms of physical dimensions, the filter has a thickness of 1.5 mm, and its circular shape is designed to fit standard optical systems. The filter is categorized as a 'Thin Lens', indicating its minimal impact on the overall optical path.
