BF590
The MidOpt BF590 Backlight fluoreSHEET allows users to achieve a backlight effect using front illumination
Traditionally. Backlights have provide sharp contrast to outline a shape, edges or an opening, but applications with space constraints may dictate that conventional backlight utilization will not be feasible. For these applications, MidOpt produces the BF590 backlight fluoreSHEET.
When the fluoreSHEET is illuminated from the front with a blue (approximately 470nm) 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.
