The MidOpt BF590 Backlight fluoreSHEET allows users to achieve a backlight effect using front illumination
Traditionally, backlights provide sharp contrast to outline a shape, edge, or opening, but applications with space constraints may make conventional backlight use infeasible. For these applications, MidOpt produces the BF590 backlight fluoreSHEET.
When the fluoreSHEET is illuminated from the front with a blue (approximately 470nm) LED, it emits orange fluorescence. A backlight effect can be created by using a MidOpt Orange Bandpass Filter (BP590) to capture the orange emission and block the blue LED excitation, giving the appearance of a bright, diffuse white background in a monochrome image.
