84-000 100 x 300 mm Kodak Wratten 2 Neutral Density Color Filter; OD 0.5 400-700nm

The 84-000 Kodak Wratten 2 Neutral Density Color Filter is a rectangular, color glass filter with dimensions of 100 x 300 mm and a thickness of 0.1 mm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.

The filter is designed to provide neutral density, which means it reduces the amount of light entering the optical system without altering the color composition. This is particularly useful in situations where the light intensity is too high, such as in bright sunlight or when using powerful light sources. The filter has an Optical Density (OD) of 0.5, which corresponds to a reduction of approximately 60% in light intensity.

The filter's wavelength is 588 nm, which is in the yellow-green part of the visible light spectrum. This wavelength is often used in applications where precise control over light intensity and color is required, such as in scientific research, photography, and cinematography.

The filter is coated on both the front and back surfaces with EDM 54-455, a proprietary coating developed by Edmund Optics. This coating is designed to enhance the filter's performance and durability, providing protection against scratches, dirt, and other contaminants.

The filter's shape is that of a thin lens, which minimizes optical distortions and ensures accurate light transmission. This makes it an ideal choice for applications where high optical precision is required, such as in imaging systems, spectroscopy, and interferometry.
