linear arrays

the heimann sensor pyroelectric linear arrays are hybrid detectors with 128 or 256 responsive lithium tantalate elements and a multiplexing read out integrated circuit. the 128 element linear array has a pitch of 100 µm and element sizes of 90 µm x 100 µm, 90 µm x 500 µm or 90 µm x 1000 µm. the 256 element linear array has 50 µm pitch and an element size of 42 µm x 100 µm. the pyroelectric chip and the read-out circuit are arranged in a metal hermetic package with an infrared window that determines the spectral sensitivity.
