LED and Broadband Light Sources ​

LED and broadband light sources are used in molecular analysis, cell research, machine vision, forensics, color measurement, and medical care. LEDs offer a much longer lifetime than conventional light sources. Broadband IR sources include thermal emitters, gas-discharge lamps, and infrared LEDs. Terahertz radiation lies between infrared and microwaves and can penetrate materials like paper, plastic, and biological tissue, making it useful for spectroscopy, non-destructive testing, and security applications.
