14-090 50 x 50 mm SCHOTT NG4 Gray Glass Neutral Density Color Filter 400-700nm

The 14-090 50 x 50 mm SCHOTT NG4 Gray Glass Neutral Density Color Filter is a high-quality optical component designed for use in a wide range of applications. Sourced from Edmund Optics, this filter is a rectangular piece of Schott NG4 glass, measuring 50 x 50 mm and 3 mm in thickness.

The filter is designed to provide neutral density, meaning it reduces the intensity of light equally across the visible spectrum, without altering its color. This is particularly useful in applications where maintaining a consistent light level is crucial, such as in photography, cinematography, and scientific research.

The filter's spectral response is defined by its cut-on and cut-off wavelengths, which are 400nm and 700nm respectively. This means it allows light with wavelengths between 400nm and 700nm to pass through, effectively covering the entire visible light spectrum.

The filter's coating is another key feature. Both the front and back surfaces are coated with the EDM 14-090 coating, which enhances its performance and durability. This coating helps to reduce reflections, increase transmission, and protect the filter from environmental factors.

The filter's shape is that of a thin lens, which makes it suitable for use in optical systems where a flat filter might cause unwanted reflections or other optical aberrations.
