83-998 100 x 300 mm Kodak Wratten 2 Neutral Density Color Filter; OD 0.3 400-700nm

The 83-998 is a 100 x 300 mm Kodak Wratten 2 Neutral Density Color Filter, available from Edmund Optics. This filter is designed to reduce the intensity of light without altering its color balance, making it an ideal choice for various applications in photography, cinematography, and optical research.

The filter boasts a neutral density of 0.3, which corresponds to a 25% transmission of light. This means it can effectively decrease the light intensity by a factor of 2, offering greater control over exposure settings. The Kodak Wratten 2 filter is designed to operate within the wavelength range of 400-700nm, covering the visible light spectrum.

The filter is made of color glass, a material known for its excellent optical properties. It has a thin lens shape, with a thickness of 0.1mm, which minimizes the potential for distortions and aberrations. The front and back surfaces of the filter are coated with EDM 53-703, a coating that likely enhances the filter's durability and performance.
