Spectral Analyses - Orphek Atlantik V4 LED Array

[Dana Riddle]

Spent the day in the lab yesterday and checked the spectral characteristics of an Orphek Atlantik V4. Data were collected through use of an Ocean Optics USB2000 spectrometer, fiber optic cable and cosine-corrected tip, and OceanView software. Integration time was 3 milliseconds (due to the intensity of the array), scans averaged =5, and boxcar was also 5. Distance from sensor to array was ~18".
Of course, the ability to manipulate intensities of LEDs in 4 channels allows an infinite number of combinations. Data below is with all channels at 100%.

@hart24601 weren't you looking for this?

I was, thanks! Great to have. I am surprised there wasn't more UV, but I guess as a percentage it gets reduced since there is such a large blue spectrum. With the 380 UV leds how low of nm did you see?

Appreciate all the great work Dana!
