A method for coating an optically reflective layer on a waveguide having an in-coupler grating, the method comprising:
- depositing an ink by screen printing on the in-coupler grating of the waveguide.
A waveguide with an in-coupler grating having a particle-free optically reflective layer generated by the deposition and sintering of a particle-free ink adhering to the in-coupler grating, wherein the optically reflective layer adhering to the in-coupler grating of the waveguide is obtained with a method for coating an optically reflective layer on a waveguide having an in-coupler grating, the method comprising:
- depositing an ink by screen printing on the in-coupler grating of the waveguide.
A lens having a length from 40 mm to 80 mm and a width from 20 mm to 60 mm, the lens including a waveguide with an in-coupler grating having a particle-free optically reflective layer generated by the deposition and sintering of a particle-free ink adhering to the in-coupler grating, wherein the optically reflective layer adhering to the in-coupler grating of the waveguide is obtained with a method for coating an optically reflective layer on a waveguide having an in-coupler grating, the method comprising:
- depositing an ink by screen printing on the in-coupler grating of the waveguide.
A screen printing device comprising:
- a loading and unloading system for waveguides;
- a handling system configured to handle waveguides loaded by the loading and unloading system;
- one or more alignment systems and one or more actuators configured to align and move waveguides handled by the handling system;
- and
- one or more screen printing heads each comprising a screen, one or more squeegees and one or more floodbars configured to apply an ink on waveguides aligned and moved by the one or more alignment systems.
