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! PDs with a glass covering

infrared photodiode
LED Microsensor NT is glad to announce new photodiodes with special glass covering with increased responsivity (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, high response speed) our photodiodes become even more impressive element base for sensors and analysers.
