The first plot illustrates the new wavelength range since I removed the IR filter from the webcam (JDEPC05 cmos sensor,) I readjusted the focusing mirror now to exactly 45 degrees and the detector at the same angle.

This is with a mirror with a reflective index of only about 50 or 55 percent, once I have the silver coated protected mirror in place, @ 45 degrees optimal angle, I will get 96 to 97 percent reflectivity, as shown in the data below;

The next image is the Solux lamp spectrum with the IR filter removed;
