OSI Optoelectronics (Hawthorne, Calif, US) has made available high-response N-on-P YAG series of photodetectors that are optimised at 1060 nm for critical military and aerospace sensing applications.

The YAG laser light wavelength combines with low capacitance, for high-speed operation and extremely low noise, making it useful for sensing low-light intensities.

Features include large active areas, high breakdown voltages, high speeds, and highly-accurate photodetection.

The Nd:YAG optimized detectors are available as single-element and/or quadrant detectors, called the SPOT Series. The SPOT Series quad detectors are ideal for aiming and pointing applications. The N-on-P devices can be used in the photovoltaic mode for low-speed applications that require low noise.  Alternatively, the optimized photodetectors can be utilized in the photoconductive mode, with an applied reverse bias, for high-speed applications.

Additional applications include laser pointing and positioning, position measurement tasks, surface profiling and guidance systems. For ranging operations, OSI’s optimized Nd:YAG photodiodes can sense light reflected from objects that are illuminated by a YAG laser beam.

OSI Optoelectronics is an OSI Systems Company.
