I analyzed the heck out of mine
One rainy weekend, I decided to map out the response curve. I rigged it up so I could illuminate it with constant light, and took a reading at each wavelength. Since the lasercheck is such a pain in the proverbial to use, this took me upwards of an hour to complete. As I went, I typed the readings into a text file on my computer. This was a great plan, until I accidentally deleted the file. After that, I couldn't remember why I wanted to map the response, so I didn't go back and collect the readings again.
