divergent beams造句

• Unlike pointers, these usually produce low-power highly divergent beams to ensure eye safety.
• For technological applications the divergent beam has to be focused, which is realized by the magnetic field of a coil, the magnetic focusing lens.
• Aconic reflectors are used in ultra violet light UV curing devices to smooth light density for a more uniform divergent beam, or a reflective curve with the intention of generating an aesthetic light effect.
• The maximum temperature allowed for the target, above which hydrogen isotopes undergo desorption and escape the material, limits the ion current per surface unit of the target; slightly divergent beams are therefore used.
• :The electrons are already focused into a very narrow, relatively non-divergent beam in the area of the target ( subject ) so they illuminate only a very small spot no matter what the " Z-Axis " position ( height ) of the target is.
• It [ now ] seems to me that it should be possible to design [ an ] apparatus by means of which a ship could radiate or project a divergent beam of these rays in any desired direction, which rays, if coming across a metallic object, such as another steamer or ship, would be reflected back to a receiver screened from the local transmitter on the sending ship, and thereby immediately reveal the presence and bearing of the other ship in fog or thick weather . }}
