The multiple integrated laser engagement system, or MILES, is used by the U.S. military and other armed forces around the world for training purposes. It uses lasers and blank cartridges to simulate actual battle. Individual soldiers carry small laser sensors scattered over their bodies, which detect when the soldier has been illuminated by a ...
Ballpoint pen. A ballpoint pen, also known as a biro [1] ( British English ), ball pen ( Hong Kong, Pakistani, Indian and Philippine English ), or dot pen [2] ( Nepali English ), is a pen that dispenses ink (usually in paste form) over a metal ball at its point, i.e., over a "ball point". The metals commonly used are steel, brass, or tungsten ...
A tunable laser is a laser whose wavelength of operation can be altered in a controlled manner. While all laser gain media allow small shifts in output wavelength, only a few types of lasers allow continuous tuning over a significant wavelength range. There are many types and categories of tunable lasers. They exist in the gas, liquid, and ...
Dichroic prism. A dichroic prism is a prism that splits light into two beams of differing wavelengths (colour). A trichroic prism assembly combines two dichroic prisms to split an image into 3 colours, typically as red, green and blue of the RGB colour model. They are usually constructed of one or more glass prisms with dichroic optical ...
A fountain pen is a writing instrument that uses a metal nib to apply water-based ink, or special pigment ink—suitable for fountain pens—to paper. It is distinguished from earlier dip pens by using an internal reservoir to hold ink, eliminating the need to repeatedly dip the pen in an inkwell during use. The pen draws ink from the reservoir ...
A Dove prism. The path of a beam through a Dove prism. A Dove prism is a type of reflective prism which is used to invert an image. Dove prisms are shaped from a truncated right-angle prism. The Dove prism is named for its inventor, Heinrich Wilhelm Dove. Although the shape of this prism is similar to the shape described by a Dovetail joint ...
Optical aberration. 1: Imaging by a lens with chromatic aberration. 2: A lens with less chromatic aberration. In optics, aberration is a property of optical systems, such as lenses, that causes light to be spread out over some region of space rather than focused to a point. [1]
