The detector is a wideband device (UVA+UVB+UVC, 221 to 358 nm). They have other devices for other wavelengths. The data sheet provides a spectral response graph, so with a bit of back-of-the-envelope calculation, or spreadsheet math, I think you could get within a couple of percent error.
The amplifier circuit has only 4 parts, which you could pop into a breadboard. No equipment required. It’s perfect for a beginner.
I think in this situation where you’re comparing products, the most important thing is consistency and reproducibility. The relative measurements are the only thing you’re interested in.
The ideal setup would use slits to sample the light, and be performed in a lightproof enclosure. You could also take several measurements while rotating the emitter through 180deg to get an angular intensity profile.
Devices which measure total light output are spherical and fairly sophisticated.
I know too well. Anyway, I thought I’d throw some ideas out there.
I think your tests are very good. Independent testing like this is very valuable to people trying to make purchasing decisions, so thank you. Never be afraid of learning new stuff! I’m always glad I did.
), thanks for the suggestions and discussion, I hope it will be picked up by someone.
