14NDF-15-2 25.4 mm Dia. Unmounted Absorptive Neutral Density Filter; OD 0.8 400-700nm

This is the 14NDF-15-2, a 25.4 mm diameter unmounted absorptive neutral density filter, specifically designed for use in the 400-700nm wavelength range. The filter is sourced from Standa, a reputable vendor known for their high-quality optical elements.

The filter is of the Neutral Density type, which means it reduces the intensity of incident light without altering its color composition. This is achieved through a front and back coating of 'sta 14ndf-0.8', which provides an Optical Density (OD) of 0.8. This OD value indicates a reduction of 75% in light intensity.

The filter is shaped as a Thin Lens, with a thickness of 3mm, and has a Base Shape of Circular. The material used in the filter is identified as 'uvfs mal- 1965'. The filter's geometry, including its 25.4mm diameter, is designed to fit standard optical systems.

The filter's information status is 'Valid - in stock', indicating it is readily available for purchase and use. For more details, you can refer to the vendor's website through the provided weblink.
