Reducing Light Intensity with Neutral Density Filters
MidOpt® Neutral Density Filters are available in a variety of optical densities and can be used with monochrome or color cameras. They are specifically designed for Machine Vision applications to reduce light intensity neutrally over a specific wavelength range without affecting image color or contrast. They can also be stacked with other Neutral Density Filters to test various optical densities.
ND200 absorptive neutral density filters have an optical density of 2.0, transmitting an average of 1% of the visible spectrum.
