Eltec Instruments, Inc.
Pyroelectric detectors respond to optical radiation at ANY wavelength which makes them potentially useful almost everywhere. Eltec's expertise is in making literally hundreds of different detector models tailored to meet exacting customer and/or application-specific requirements. Some basic representative detector models are posted on this site to give an idea of the various types of detectors / detector styles available. Please note these are high performance instrumentation-grade detectors, not the devices in common lighting controls, household burglar alarms and other consumer products.
