Yes – this is turning into quite an interesting project. I’m using x6 White, water clear LED’s, with a viewing angle of 60° and a light output of 1000 mcd each. I’m not to sure of the overall brightness of the final system, so I’m leaving the design open so I can add more, or remove a couple, to ensure I obtain an even illumination across the field, of the correct intensity, to allow flat field exposures in the range of 1 to 10 seconds.
I won’t know the answers until I build the first 6 LED prototype using a white bucket from Bunnings. Once I have taken some flat field frames, I can then inspect them in one of the imaging applications, to check the evenness of illumination.
What I like about the LEDs are their robustness, low power and low heat characteristics, compared to incandescent bulbs.
Cheers
