Periodically, I look at these and wonder if I could ever afford to have (built-for-me) a small 255nm UV-C flashlight...
But ignore my dreams for a moment, ignore the wavelength and anemic power output, and take a glance at the column with prices.
What practical application could a $3500 emitter or a $6000 emitter possibly have? WHO IS BUYING THESE? What are they used for? If a few grams of emitter costs $6K, what is it built into, and how much does THAT cost?
Are we certain that diamond is a poor material for building flashlights? How about smelting irony meteorites and Moon rocks brought back by the Apollo Astronauts for extraterrestrial metals (just to inflate the cost to "impossible to afford")? Don't answer that, its a joke, but I don't understand the manufacture of something that very few individuals could afford, and any industry that needs these would necessarily need to be essential and profitable. And qphotionics keeps these emitters IN STOCK. How can they afford to do that?
