Congratulations! I think that is fantastic and it looks like it would be brilliant for a Univeristy teaching lab
Thanks! Yes I think that using a grid of LEDs is a great idea for illumination. I'm not sure if the 1-step imaging from the bottom would work with all of the LEDs on at once. My concern is that you would get light contamination between the different wells if they are all illuminated at once. I think you could solve that by collimating the light sources, but that would be a pain. Might be easier to illuminate them sequentially?
I think that is a great idea, not stupid at all. There are some limitations. Because the RGB LEDs are really just 3 LEDs in the same case (red, blue, green) I think that you would want to use just those three peak wavelengths (which should be on the datasheet for the LED). The RGB LEDs make a range of colours by combining outputs from the R, G and B - but those mixtures aren't great for spectrophometry, where you want a sharp peak at the desired wavelength. Hope that makes sense and good luck
