Laser guidance is used by military to guide a missile or other projectile or vehicle to a target by means of a laser beam, either beam riding guidance or semi-active laser homing (SALH). [7] With this technique, a laser is kept pointed at the target and the laser radiation bounces off the target and is scattered in all directions (this is known ...
Laser filters protect the operator against being dazzled/blinded by potential laser light sources. These filters are often an internal part in the assembly of lens elements. Scope cover , a semi-soft pouch that protects the sight from accidental collisions or the elements during transit and storage.
A laser sight is a device attached or integral to a firearm to aid target acquisition. Unlike optical and iron sights where the user looks through the device to aim at the target, laser sights project a beam onto the target, providing a visual reference point.
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.
Laser engraving metal plates are manufactured with a finely polished metal, coated with an enamel paint made to be "burned off". At levels of 10 to 30 watts, excellent engravings are made as the enamel is removed quite cleanly. Much laser engraving is sold as exposed brass or silver-coated steel lettering on a black or dark-enamelled background.
Laser alignment systems represent a more traditional approach. These systems utilise fixed heads attached simply to, or hung from each wheel, projecting laser beams to measure angles and positions. While generally considered less precise than newer technologies, laser systems are often praised for their robustness and reliability, making them a ...
Iron sights are a system of physical alignment markers used as a sighting device to assist the accurate aiming of ranged weapons such as firearms, airguns, crossbows, and bows, or less commonly as a primitive finder sight for optical telescopes. Iron sights, which are typically made of metal, are the earliest and simplest type of sighting device.
Incremental improvements in laser process and control technologies have led to substantial increases in the number of cooling holes used in turbine engines. Fundamental to these improvements and increased use of laser drilled holes is an understanding of the relationship between process parameters and hole quality and drilling speed.
