12. Limitations for application in analytical instruments
› Dynamic variations between the LEDs
› High cost for UVC/UVB chips
› Different aging characteristics
› Lifetime is defined by LED with the shortest lifetime
› Failure of a single LED causes failure of the entire device
› Difficulties in optical setup for analytical instruments
› A Point source is required for optical imaging
› The Image will show patterns of different wavelengths
