Pricier than its red laser cousin the GLL30, but more powerful into the bargain, this compact laser level will provide as much guidance as most DIY enthusiasts need, with the advantage of brighter ...
Mounting new kitchen cabinets or hanging a few pictures? Keep your stuff level and straight with these tried-and-tested gadgets.
The concept of a laser level has been around since at least the early 1970s, [2] the original spinning-mirror design laser plane and line level was patented by the late 1980s, [3] and the compact lens-based laser line level (as produced by many tool manufacturers today) was patented in the late 1990s. It was invented by Oscar Soliz in the late ...
A laser line level is a tool combining a spirit level and/or plumb bob with a laser to display an accurately horizontal or vertical illuminated line on a surface the laser line level is laid against. Laser line levels are used wherever accurate verticals and horizontals are required, typically in the construction and cabinetry industries. Some ...
Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
Also known as low-level laser therapy (LLLT) or photobiomodulation, this non-invasive procedure involves exposing the targeted area of the body to low levels of red or near-infrared light.
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the ...
Pr:YLF laser lasing at 523 nm. The Pr:YLF crystal fluoresces white. The intracavity beam can be seen through rayleigh scattering because of its high intensity.. A Pr:YLF laser (or Pr 3+:LiYF 4 laser) is a solid state laser that uses a praseodymium doped yttrium-lithium-fluoride crystal as its gain medium.
