I looked it up and Far-UVC (typically 222 nm) seems safe-ish. But how do you confirm it's not outputting 254 nm or other wavelengths in the UVA/B range? Seems likely to happen with sloppy production of sources. You really have to trust the filter on the light or verify the frequency somehow.
- jefftk 9mo ago(author) The non-profit OSLUV evaluates lamps and measures their emissions. Here's their evaluation for the Aerolamp, which is the one I've purchased: https://reports.osluv.org/static/assay/aerolamp%20devkit--27c4ca60-0da7-4669-8cc7-36746a06fb62--R00.html https://reports.osluv.org/static/assay/aerolamp%20devkit--27...
- Retz4o4 9mo agoOSLUV is fantastic; doing great work.
- Bad_Initialism 9mo agoWell, just use your USB spectrometer, of course. ...you do have a USB spectrometer, don't you? I have mine in my bedside drawer. I use it almost as often as my multimeter.
- briandw 9mo agoI need to get one :)
- philipkglass 9mo agoDoes yours measure wavelengths that short? A lot of low cost spectrometers don't, because inexpensive glass and plastic optics transmit visible and near-IR radiation but significantly impair shorter UV wavelengths.
- ansgri 9mo agoDo you have a recommendation for an inexpensive one? I’ve worked with OceanOptics Flame series, but they’re not exactly cheap, and their software was crap.
