Press Release Summary:
Series Nd:YAG can be used in photovoltaic or photoconductive mode. Sensing areas of Quad photodetectors are divided into 4 independent quadrants. Models SPOT-15-YAG and SPOT-9-YAG offer sensing areas of 15 and 9 mm, respectively. Single-element Models PIN-100-YAG and PIN-5-YAG have sensing areas of 100 mm² and 5 mm², respectively. N on P silicon units operate in fully depleted mode to satisfy high-speed requirements of military and commercial applications.Original Press Release:
New Optimized YAG-Series Photodetectors
Hawthorne, CA - February 13, 2003 - UDT Sensors, Inc., a subsidiary of OSI SYSTEMS (Nasdaq: OSIS), announces a new series of YAG photodetectors, optimized for high-speed operation and high responsivity at 1064nm. The new Nd:YAG series offers two 4-element (Quad) detectors and two Single-element configurations. These N on P silicon devices operate in a fully depleted mode, to satisfy the high speed requirements of Military and Commercial applications. They can sense low-light intensities, such as the light reflected from objects illuminated by a YAG laser beam for ranging applications.
The Quad photodetectors' sensing areas are divided into 4 independent quadrants. The total sensing area diameters for the SPOT-15-YAG and the SPOT-9-YAG are 15mm and 9mm, respectively. Their applications include laser aiming and pointing, position measurement, surface profiling and guidance systems.
The Single-element PIN-100-YAG and PIN-5-YAG have sensing areas of 100mm² and 5mm², respectively. These detectors have large sensing areas and high breakdown voltages. For extremely low capacitance and rise time, the PIN-YAG series detectors may be biased at voltages up to 100V.
Both YAG series can be used in the photovoltaic mode, for low-speed applications requiring low noise, or in the photoconductive mode, with an applied reverse bias, for high-speed use. All Nd:YAG series products are available in rugged, metal packages.
