PDs with a glass covering
Microtech BG 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.
