This is the 14NDF-60-2, 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 composition. This is achieved through a front and back coating of 'sta 14ndf-0.2', which provides an Optical Density (OD) of 0.2. This level of OD corresponds to a reduction in light intensity of approximately 20%.
The filter is shaped as a Thin Lens, with a thickness of 3mm, and has a base shape of a Circle. The material used in the filter is identified as 'uvfs mal- 1965'. The filter's information is currently in stock and available for immediate purchase, as indicated by its weblink status.
