The MidOpt FL550-52 is used to eliminate the strong greenish color that often results when illuminating with white fluorescent lighting. The FL550 absorbs light in the middle of the visible spectrum, which is where most color cameras have their strongest response, eliminating a greenish cast, resulting in true-to-life color rendition. All MidOpt filters can also be purchased unmounted and in custom dimensions upon request from Machine Vision Direct.
