040FN46-50 50mm Dia. Fused Silica Standard UV Neutral Density Filter, OD=0.4

This is the 040FN46-50 Fused Silica Standard UV Neutral Density Filter, a high-quality optical component designed for use in a wide range of applications. The filter is manufactured by Andover Corporation, a leading vendor in the field of optical elements.

The filter is circular in shape with a diameter of 50mm and a thickness of 1.5mm, making it suitable for use in systems with limited space. It is made of fused silica, a material known for its excellent optical properties, including high transparency, low autofluorescence, and excellent thermal stability. The material is identified as "fused sil mal-1965" in the item data.

The filter features a Neutral Density coating on both the front and back surfaces, identified as "and 040fn46". This coating reduces the intensity of light passing through the filter without altering its color, making it ideal for applications where light intensity needs to be controlled, such as in photography, laser applications, and scientific research.

The wavelength of this filter is 588nm, which is in the visible light spectrum. This makes it suitable for use in applications where visibility and color accuracy are important.

The filter has a thin lens shape, which is beneficial in systems where weight and space are critical factors. It is currently in stock and available for purchase through the vendor's website, as indicated by the "weblink status" in the item data.
