14NDF-3-2 25.4 mm Dia. Unmounted Absorptive Neutral Density Filter; OD 1.5 400-700nm

This is the 14NDF-3-2 Unmounted Absorptive Neutral Density Filter from Standa, a renowned vendor in the optical industry. The filter is designed with a diameter of 25.4 mm and a thickness of 3 mm, making it a compact and efficient solution for various 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 particularly useful in photography, cinematography, and scientific research where controlling light intensity is crucial. The filter's coating, Sta 14ndf-1.5, is applied on both the front and back surfaces, ensuring consistent performance and durability.

The 14NDF-3-2 filter is designed to operate within the wavelength range of 400-700nm, covering the visible light spectrum. Its Optical Density (OD) is 1.5, which translates to a reduction of 90% in light intensity. This makes it a medium-light reduction filter, suitable for situations where moderate light control is required.

The filter's geometry is shaped as a Thin Lens, which is beneficial in maintaining the optical path and minimizing aberrations. It is unmounted, providing users the flexibility to integrate it into their existing optical systems or mounts.
