IA35 Photodiode - Heterostructure Photodiode on an InAs Substrate | |
28 Nov 2018 LASER COMPONENTS is a world leading manufacturer of photovoltaic indium arsenide detectors. From our research and production facility in Arizona we supply customers all over the world with these industrial grade quantum sensors. The semiconductor material absorbs incident IR photons generating electron hole pairs which are collected at external electrodes. Photovoltaic detectors are an excellent choice in many applications due to their high sensitivity, fast response, low noise and wide dynamic range. Our IA35 is a heterostructure photodiode on an InAs substrate with a relatively wide peak at 2.8 microns. The IA35 has a 0.5mm diameter chip and is designed specifically for uncooled operation and has a spectral range of up to 3.5microns, 20% cut off . The curve of the spectral response can be seen in the image shown. Compared to standard InAs products the IA35 offers double the shunt resistance with a quadrupled area. The devices are manufactured in standard TO style packages and have long expected lifetimes making them ideal for fit and forget applications such as gas analysis, non-contact temperature measurement, laser monitoring and spectrophotometry.
