New optoelectronic devices for the Near and Mid-Infrared spectral range open completely new possibilities for portable sensors creation. Using infrared LED-PD optopairs allows developing an instrument that is smaller, less expensive and energy-saving.
Visual InspectionVisual inspection is an indespensable part of the quality control process, which helps to detect defective devices on the following stages of manufacturing:
- Control of the grown structure
- Photolitography and chip separating grid forming
- Cuting the structure into the single chips
- Packaging of LED chips from the structure
