Microtech BG 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.
The following models are available:
