14NDF-1-3 50.8 x 50.8 mm Unmounted Absorptive Neutral Density Filter; OD 2 400-700nm

Standa's 14NDF-1-3 is a rectangular unmounted absorptive neutral density filter, designed to reduce the intensity of light without altering its color composition. This filter is particularly useful in photography, cinematography, and scientific research where controlling light intensity is crucial.

The filter boasts a size of 50.8 x 50.8 mm, making it compatible with a wide range of optical systems. It has a thickness of 3 mm, providing durability and resistance to external pressures. The filter's base shape is rectangular, which is ideal for applications requiring a larger active area than circular filters can provide.

The 14NDF-1-3 filter is coated with Sta 14ndf-2 on both the front and back surfaces. This coating enhances the filter's performance by ensuring consistent attenuation across the entire spectral range of 400-700nm. The coating also provides excellent scratch resistance, ensuring the filter maintains its optical properties over time.

The filter's geometry is defined by its width, height, and thickness. With a width and height of 50.8 mm each, it provides a generous active area. The thickness of 3 mm ensures structural integrity and minimal optical distortion.

This filter is of the thin lens shape, which is beneficial in applications where space is limited or where maintaining a flat profile is critical. It is sourced from Standa, a reputable vendor known for its high-quality optical elements.
