Visible wavelength range is between 400nm-700nm, human eyes are
difficult or unable to observe more than 700nm wavelength laser.
Infrared up-conversion card are usually adopted when observe
more than 700nm wavelength laser, which is made of a special
phosphor material, a shorter wavelength and higher frequency
laser will be released when the card receive a certain frequency
laser, so human eyes can observe.
Infrared laser display card is used to display
infrared laser spot. CNI
infrared laser display card is convenient for observe 700nm to
1600nm laser spot, which with features of high brightness, high
contrast image with edge-to-edge sharpness. |
