Servo Corporation's Model 1501 pyroelectric single-element IR detector is designed for use in infrared applications requiring a compact, rugged design with high sensitivity and proven reliability.
Process Control Instruments
Space Borne Radiometers
Satellite Earth Sensors
The Model 1501 single-element detector is available in two configurations: 1501 VM (voltage mode) and 1501 CM (current mode). Both devices come standard in a hermetically sealed TO-5 package. Elements are photo-lithographically defined onto specially processed lithium tantalate crystals and range in size from 0.5mm to 2.0mm square. Detectors windows are AR coated for enhanced transmissivity with selections available in the 2 to 15 micron range.
