An effective method to introduce light shielding into transparent plastics.
Light shielding in backlit components avoids light bleeding into neighboring operating elements.
Light shielding in backlit components are usually created by elaborate 2-color back injection molding. Laser Deep Printing opens up significant cost savings in terms of
Location-controlled focussing of ultra-short pulsed lasers creates visible dots, lines, areal and even complex geometric structures/shapes in transparent plastics.
Modified structures are built from the bottom up. Single pulse processing leads to separated structural elements.
The effect of spherical abberation leads (without a corresponding corecture) to an expansion of the introduced structure in the z-direction. The expansion in x,y direction remains unchanged.
Minimum structure sizes in x,y, and z-direction are about 2µm.
Laser Deep Printing - Variables
Cage-like or tubular structures act as a light shielding to prevent over-illumination into neighbouring areas.
The light barriers were introduced into various transparent plastics
