250FN52-12.5 12.5mm Dia. Green Glass Standard VIS-NIR Neutral Density Filter, OD=2.5
This is the 250FN52-12.5, a 12.5mm diameter Neutral Density Filter, specifically designed for the visible (VIS) and near-infrared (NIR) spectrum. The filter is sourced from Andover Corporation, a reputable vendor in the optical industry.
The filter is of the Neutral Density type, which means it reduces the intensity of light without altering its color. This is particularly useful in various applications where controlling light intensity is crucial, such as in photography, cinematography, and scientific research.
The filter is made of soda lime ru green material, a common choice for optical filters due to its excellent optical properties and durability. It has a base shape of a circle, a standard geometry in optical filters for ease of integration into various systems.
The 250FN52-12.5 has a thickness of 1.52mm, providing sufficient structural integrity while maintaining a compact profile. The filter features coatings on both the front and back surfaces, identified as 'and 250fn52'. These coatings enhance the filter's performance and durability.
The filter is designed to operate at a wavelength of 588nm, a common range for VIS-NIR applications. It is currently in stock and available for immediate use. For more information, you can refer to the vendor's website through the provided weblink.
