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.

Light Emitting Diode Arrays and Matrices

Tiny dimensions of an LED chip (0.35 × 0.35 mm), narrow-band emission spectrum, short response time and low thermal flux enables the creation of very compact multi-element LED arrays and LED matrices emitting at one or different wavelengths.

What is the LED Matrix?

The LED matrix is a kind of arrangement of similar or different LED-chips mounted in a single compact package and driven together or independently. This kind of emitter is a powerful radiation source for portable optical analysing systems.
✔ Parallel connection of several LED chips that emit at the same wavelength and driving them together can provide a significant increase of total optical power.

✔ Connecting LED chips that emit at different wavelengths and driving them independently, or applying short current pulses sequentially to each chip, enables scanning of a certain spectral range with the help of a very compact radiation source.

✔ There is also a possibility to design a custom matrix combining different LED chips and choosing appropriate package.
