1064 nm Optimized Quadrant Photodetectors

The SPOT-YAG series are 1064 nm Nd:YAG optimized quadrant photodiodes that are well suited for aiming and pointing applications. The high performance P-type devices are manufactured with a guard ring that collects current generated outside the active to reduce noise.

They offer low capacitance and high-speed response times and are ideal for low light intensity measurements due to their low noise and high responsivity.  The detectors can be operated both in photovoltaic mode (unbiased), for applications requiring low noise, or biased in the photoconductive mode, for high-speed applications.
