080FN52-25 25mm Dia. Green Glass Standard VIS-NIR Neutral Density Filter, OD=0.8

The 080FN52-25 is a Neutral Density Filter with a circular shape and a diameter of 25mm. This filter is sourced from Andover Corporation, a renowned vendor in the optical industry. It is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically at a wavelength of 588nm.

The filter is made of soda lime ru green material, a common choice for its excellent optical properties and durability. It has a thickness of 1.52mm, which is standard for this type of component. The front and back surfaces of the filter are coated with the Andover Corporation's proprietary coating, identified as 'and 080fn52'. This coating enhances the filter's performance and longevity.

The filter's Neutral Density (ND) is 0.8, which means it reduces the intensity of incident light by a factor of 6.31 (1/0.8). This feature is crucial in applications where controlling light intensity is paramount, such as in imaging systems, spectroscopy, and beam profiling.

The filter is designed in a Thin Lens shape, which is advantageous in applications where space is limited or a thin, lightweight component is required. The filter's geometry and coating make it suitable for a wide range of optical applications.
