  4. Laser cutting - Wikipedia

    en.wikipedia.org/wiki/Laser_cutting

    Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics.

  5. Reflector (cipher machine) - Wikipedia

    en.wikipedia.org/wiki/Reflector_(cipher_machine)

    Reflector (cipher machine) A reflector, in cryptology, is a component of some rotor cipher machines, such as the Enigma machine, that sends electrical impulses that have reached it from the machine's rotors, back in reverse order through those rotors. The reflector simplified using the same machine setup for encryption and decryption, but it ...

  7. Laser flash analysis - Wikipedia

    en.wikipedia.org/wiki/Laser_Flash_Analysis

    The laser flash analysis or laser flash method is used to measure thermal diffusivity of a variety of different materials. An energy pulse heats one side of a plane-parallel sample and the resulting time dependent temperature rise on the backside due to the energy input is detected. The higher the thermal diffusivity of the sample, the faster ...

  8. Prism spectrometer - Wikipedia

    en.wikipedia.org/wiki/Prism_spectrometer

    Prism spectrometer. A prism spectrometer is an optical spectrometer which uses a dispersive prism as its dispersive element. The prism refracts light into its different colors ( wavelengths ). The dispersion occurs because the angle of refraction is dependent on the refractive index of the prism's material, which in turn is slightly dependent ...
