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.

NEW! LEDs with a glass covering

LED Microsensor NT is glad to announce new light-emitting diodes with special glass covering with increased LED output optical power (up to 3-5 times). This allows obtaining higher accuracy in different gas, liquids and solids sensing and analysis applications. Together with other advantages (compact size, low power consumption, high modulation range) our LEDs become even more impressive element base for sensors and analysers.
