Saturation and Brightness were very subjective, but relative values were consistent It's unknown what the filtering characteristics of the UV Filter and PC (PolyCarbonate) Glasses are; but data suggests the UV filter starts ~400nm and pretty complete by 380 - PC slightly more. Near the end, it was helpful to use the UV filter to determine if I was just seeing residual light in the Monochromator ... or if I was actually see emitted light from it. The Monochromator says that it is "rated" for 360-830nm. So while it "took" lower values, it's possible it does not put out much light energy as it drops below 360nm ... so it's possible there wasn't anything to see there!
