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.
Near- & Middle-Infrared LEDsOur near-infrared (1000-2500 nm range) and mid-infrared (2800-5000 nm range) Light emitting diodes (LEDs) possess certain competitive advantages:
✔ Compact size of the LED chip – 0.35x0.35 mm
✔ Possibility to arrange multi-element arrays enables obtaining multi-wavelength emitters in single compact packages
✔ No need of optical filters - LEDs emission band widths are comparable with absorption band widths of many chemical agents
✔ Capability to provide sufficient selectivity and accuracy for different sensing applications
✔ Low power consumption ( <1 mW)
✔ Short response time – 10-50 ns
✔ Modulation ranges of up to 100 MHz can be achieved
✔ Operation temperatures up to +150°C
✔ Lifetime 80 000 hours
One-element LED models with 1.0-2.4µm peak wavelengths (near-infrared region) and 2.8-5.0µm (middle-infrared region).
