Wavelength-sensitive photodiode C30641GH

infraredLIDARInGaAs

Product overview
The C30641GH is a large-area InGaAs PIN photodiode with a 1.0 mm active diameter chip housed in a TO-18 package with a flat glass window. It delivers high quantum efficiency from 800 nm to 1700 nm, with low dark current, high shunt resistance and low capacitance for fast response and accurate measurements. The detector shows uniformity within 2% across the active area, suitable for precision optical instrumentation and sensing applications.
