LED Wafer High Brightness Optical Coating

Use Distributed Bragg reflection mirror (DBR) to increase the luminous efficiency of LED. 

Vti can produce the following different reflective layer functions according to customer needs.

※ White LED is optimized for high reflectivity coating design.
※ Remove harmful blue light and improve the light extraction efficiency of  white LED.
※ UV-A and B LED use high reflectivity coating to achieve UV high reflection effect.
※ UV-C and high-energy laser application design and production, etc.
