130FN46-50 50mm Dia. Fused Silica Standard UV Neutral Density Filter, OD=1.3

The 130FN46-50 is a 50mm diameter Fused Silica Standard UV Neutral Density Filter, boasting an Optical Density (OD) of 1.3. This filter is sourced from the Andover Corporation, a renowned vendor in the optical industry.

The filter is designed with a circular base shape, making it compatible with a wide range of optical systems. It is constructed from fused silica, a high-quality material known for its excellent optical properties, including high transparency and resistance to thermal shock. The material's ID, as per the vendor's classification, is "fused sil mal-1965".

The filter's primary function is to reduce the intensity of light passing through it, without altering the color composition. This is particularly useful in high-intensity light situations, where it is crucial to protect the optical system from potential damage. The wavelength at which this filter operates is 588nm.

In terms of geometry, the filter has a diameter of 50mm and a thickness of 1.5mm. This compact design ensures easy integration into various optical setups. The filter is coated on both the front and back with the Andover Corporation's proprietary coating, denoted as "and 130fn46", which further enhances its performance and durability.

The filter's shape is classified as a Thin Lens, indicating its ability to focus light without introducing significant aberrations. This makes it an ideal choice for applications that require high-precision optical performance.
