In the UK, "Class Two" lasers are limited to a maximum output power of one milliwatt
. Guidelines say that lasers rated higher than Class Two are "too powerful for general use as laser pointers and present an unacceptable risk in the hands of the consumer".
Lead scientist Dr Kate Fox, from RMIT University in Melbourne, said: "At that upper level, the beam would cause catastrophic retinal damage." In the UK, "Class Two" lasers are limited to a maximum output power of one milliwatt
with a beam wavelength of between 400 and 700 nanometres (nm).
"The devices are often incorrectly marked - I have seen many devices marked as one milliwatt
devices but with output powers way in excess of this."
He said: "The lasers that are used as pointers in the classroom are low powered, they are about one milliwatt
The winning turbine - constructed by her students Cheyenne Cole, 14, Erika Luis Lopez, 13, and Nathan Edwards, 13 - produced more than 1,800 milliwatt
When running on solar power alone, it draws less than 10 milliwatts
. While the Claremont is a research demonstrator, Intel could adapt the technology for commercial chips, the company's chief technology officer, Justin Rattner, said.
A 32-bit RISC baseband and a 32-bit RISC Applications Processor will each process about 200 to 240 triangles per second per milliwatt
. In comparison, the MiMagic 6 APA multimedia engine can deliver up to 20,000 triangles per second per milliwatt
Marinelli exposed leukemia cells to cell-phone band radiation at a power level of 1 milliwatt
and examined the activity of a gene that controls apoptosis, or normal cellular self-destruction.
"Any attempt to touch the AUTO TASER zaps the thief with an unforgettable, yet non-lethal 5,900 milliwatt
This device has been included in Class II, which is reserved for laser sources with outputs below 1 milliwatt
. Class II lasers are considered safe except for deliberate long term exposure by staring directly into the beam.
"There's a lot of poorly controlled devices from the Far East and you can quite easily buy five to seven thousand watt examples, compared to the one milliwatt
devices available a few years ago.
It also features a built-in multimeter for displaying voltage, current, power and milliwatt
hours on the integrated OLED display.
