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 ...
In surveying and construction, the laser level is a control tool consisting of a rotating laser beam projector that can be affixed to a tripod. The tool is leveled according to the accuracy of the device and projects a fixed red or green beam in a plane about the horizontal and/or vertical axis.
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 ...
The laser receiver detects the height of laser plane with an array of photo diodes, generally a series of photo diodes in 9" strip with a gap between diodes equal to the width of the beam. the receiver reads the height with the sensors and convert to a usable analog or digital signal and sends to the machine control unit. Modern systems use CAN ...

A growing body of evidence has shown links between cancer and drinking alcohol. In a warning Friday, U.S. Surgeon General Vivek Murthy said cancer risk increases with the number of drinks, but ...
An optical parametric amplifier, abbreviated OPA, is a laser light source that emits light of variable wavelengths by an optical parametric amplification process. It is essentially the same as an optical parametric oscillator , but without the optical cavity (i.e., the light beams pass through the apparatus just once or twice, rather than many ...
