LEDs are opto-semiconductors that convert electrical energy into light energy. LEDs offer the advantages of low cost and a long service life compared to laser diodes (LDs).
LEDs are grouped into visible LEDs and invisible LEDs. Visible LEDs are mainly used for display or illumination, where LEDs are used individually. Invisible LEDs, however, are mainly used with photosensors such as photodiodes or CMOS image sensors.
Hamamatsu provides various LEDs from red to mid infrared range, which are mainly used in combination with photosensors.
A product lineup that covers a variety of wavelengths based on crystal growth technology and process technology that support compound semiconductor materials are available. High quality and reliability are backed by strictly controlled assembly and inspection processes.
