Advanced Photonix is a leading manufacturer of custom photodiodes and photodiode-based subsystems, in both photoconductive and photovoltaic formats. We manufacture photodiodes and photocells using a number of materials including Si, InGaAs, and CdS.



CdS Photocells

Advanced Photonix’ Cadmium Sulfide (CdS) photocell technology (also known as photoconductive cell, light dependent resistor, photoresistor or photoconductor) is used in various applications for detection and characterization of flame, in oil and gas burners, optocouplers for electrical isolation and audio applications, as well as general lighting detection for street lighting, cell phones, and many other applications.



Avalanche Photodiodes

Advanced Photonix is the world’s leading supplier of custom and standard Large Area Avalanche PhotoDiodes (LAAPD’s) and  Avalanche Photodiodes (APD’s).  The silicon avalanche photodiode (Si APD) is a photon detection device that offers high internal gain. It is ideal for use in high speed, low light level applications.




Multi-Element Photodiodes

Advanced Photonix specializes in the design and manufacture of custom photodiode arrays.  By combining multiple elements into various configurations, photodetector arrays offer enhanced detection performance for applications such as scanning, process monitoring, low-resolution imaging, liquid level sensing, missile guidance, and many others.
