MidOpt introduces the Backlight fluoreSHEET™, which creates a backlight effect with front illumination and is ideal for space-constrained applications. When the Backlight fluoreSHEET™ is illuminated from the front with a blue LED light, it emits an 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 white diffuse background in a monochrome image.
