Keyence Corporation (キーエンス, Kīensu) is a Japan-based direct sales organization that develops and manufactures equipment for factory automation, sensors, measuring instruments, vision systems, barcode readers, laser markers and digital microscopes.
The change in intensity is measured by a single-frequency laser that matches the cavity's resonant frequency.The device can sense displacements under 1 femtometre (10 −15 m) and detect accelerations as low as 3.2 × 10-8 g (the acceleration due to Earth's gravity) with uncertainty under 1%.
ProCite versions 3.x-5.x ran on Microsoft Windows. Version 3.0 for Windows was released in 1995. [7] MacIntosh versions were also published. [8] [9] ProCite 3.1 and later versions included a Z39.50 client for searching and downloading records from library catalogs and other databases providing a Z39.50 server.
Most types of laser are an inherently pure source of light; they emit near-monochromatic light with a very well defined range of wavelengths.By careful design of the laser components, the purity of the laser light (measured as the "linewidth") can be improved more than the purity of any other light source.

Hand-held laser scanners create a 3D image through the triangulation mechanism described above: a laser dot or line is projected onto an object from a hand-held device and a sensor (typically a charge-coupled device or position sensitive device) measures the distance to the surface. Data is collected in relation to an internal coordinate system ...
A laser warning symbol. Laser radiation safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations.
A coherent perfect absorber (CPA), or anti-laser, is a device which absorbs coherent waves, such as coherent light waves, and converts them into some form of internal energy, e.g. heat or electrical energy. [1] [2] It is the time-reversed counterpart of a laser. [3]
