New optoelectronic devices for the Mid-Infrared spectral range open completely new possibilities for portable sensors creation. Using Mid-infrared LED-PD optopairs allows developing an instrument that is smaller, less expensive and versatile.
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
