Which type of colored filter is best for my imaging application?

While there are different types of colored filters that will work for imaging applications, generally colored glass filters or films are the best choice. Dichroic color filters are not typically recommended for imaging use. The color separating that is done by dichroic filters is angularly dependent. As the angle of light coming into the filter increases from the filter's center, the colors that the dichroic filter transmits shifts from the design wavelengths. The effect is that light in the center of a red filter will pass through as red, but light at a large angle (i.e., at the edge of the filter) may pass through as orange or even yellow.
