14NDF-50-2 25.4 mm Dia. Unmounted Absorptive Neutral Density Filter; OD 0.3 400-700nm

This is the 14NDF-50-2, a 25.4 mm diameter unmounted absorptive neutral density filter, sourced from the reputable vendor, Standa. The filter is designed for use within the wavelength range of 400-700nm, making it suitable for a wide range of optical applications.

The filter is of the Neutral Density type, which means it reduces the intensity of light without altering its color. This is achieved through the absorption of light, as indicated by the 'absorptive' in its name. The filter has an Optical Density (OD) of 0.3, which corresponds to a reduction of 20% in light intensity.

The filter is circular in base shape and made from UVFS Mal-1965 material. It has a thickness of 3mm, which contributes to its durability and stability in optical systems. The coating on both the front and back surfaces of the filter is Sta 14ndf-0.3. This coating enhances the filter's performance and longevity.

The filter's geometry is that of a thin lens, which makes it compatible with various optical systems. The catalog number for this item is 14NDF-50-2, and it can be found on Standa's official website. The link is provided in the item data, and the status indicates that it is currently in stock.
