InGaAs Photodiodes feature excellent responsivity from 900nm to 1700nm with active areas ranging from 0.07mm to 3.0mm. Photodiodes with active area sizes less than 1mm provide low capacitance, low dark current, and high responsivity from 1100nm to 1620nm, for high speed datacom and telecom applications. Photodiodes with active area sizes of 1mm and up provide large active areas, low noise, and high shunt resistance enabling high sensitivity for weak signals. InGaAs Photodiodes are isolated in TO-46, TO-18, or TO-5 packages with either a ball lens or double-sided AR coated window, depending on the packaging. These photodiodes are ideal for a multitude of research and OEM applications including IR laser alignment, medical diagnostics, and chemical analysis.
