ACEBEAM Wide Spectrum BLOS (Beyond-Line-of-Sight) Searchlight W10 & W30 compared with Other Laser Light
We know this device uses a led phosphore (P) excited by a blue or violet laser to produce white light. I wonder what result could be produced by exciting such a phosphore with a collimated beam expander (BE)Yes, it’s a flashlight, but a very tight beam for such.
Actually the Acebeam' s beam is collimated, though poorly. I still wonder what result would be produced. Would it create a flood effect or a semi narrow beam?My understanding from something Cyparagon, (or maybe it was Paul) posted a couple of years or more ago is the florescence is not at all coherent, so focusing a beam on the material whether collimated, or uncollimated cannot produce anything different.
Technically they aren't wrong. They say, "white laser light". Both units and similar cars headlights use a laser as the source.The title of this thread kept me away as it is NOT a white laser! As for long throwing flashlights, I suppose it could be useful there, but they shouldn't claim it as a laser.
That's why I said "technically".Well, it has a laser inside, but I agree, a bit misleading, however, closer to a laser at 31 mRad than any hand held flashlight I know about.
Technically, they are. I did several experiments a few years ago with fluorescent materials excited by a laser and measured the output with my spectrometer. The outputs were FAR from coherent light and had a basic output similar to LEDs, but much wider.Technically they aren't wrong. They say, "white laser light". Both units and similar cars headlights use a laser as the source.
