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 Inspection

Visual 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
