OSI Optoelectronics offers the N-on-P YAG series photodetectors, optimized at 1,060 nm for critical military and aerospace sensing applications. According to the company, 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 optimized detectors are available as single-element and/or quadrant detectors, called the SPOT Series. The SPOT Series quad detectors are viable 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 devices can be used 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.
