Pyroelectric Detectors

DLATGS Pyroelectric Detectors

DLATGS Pyroelectrics are the highest performing thermal detectors combining broad spectral sensitivity, high D*, with frequency response. The DLATGS crystal used to produce the sensing element is the latest development in pyroelectric materials.  Its polarization is “locked in” thus no longer requiring a poling voltage to maintain the output signal level.  The Curie temperature is also raised to be above 60 C. The Product Matrix below will help you choose the right device for your application.
　

　

Lithium Tantalate Pyroelectric Detectors

Lithium Tantalate (LTO)  Pyroelectrics are the often the best compromise between cost and performance of the common pyroelectrics.  With a very high Curie temperature and a low temperature coefficient of response (<~.2%/ deg C. ) they can operate over all commercial, industrial and aerospace environments.  This permanently poled rugged crystalline material is also non hygroscopic and can be operated in windowless configurations.  Available in many active areas and electronic configurations these thermal detectors combine broad spectral response and high D* at an affordable price. The Product Matrix below will help you choose the right device for your application.
