Red LED’s Wafers 650-660nm
Our company manufactures a wide range of "red" emitting structures according to concrete requirements of customers, which are characterized by a certain set of parameters, such as:
-
type of structure (SH, DH or DDH);
-
quantity and type of epitaxial layers;
-
emission power;
-
peak wavelength of emission;
The structures are made as round wafers with diameter 37-40mm or 50mm and with thickness 150-450 microns.
Main types of structures are indicated in the following Table:
