With a pitch of 100 \u03bcm (128 elements), 50 \u03bcm (256 elements) or 25 \u03bcm (510 elements), the pixel length was increased to typically 500 \u03bcm. By reducing the element thicknesses to values around 5 \u03bcm by means of modern ion beam etching processes, the noise equivalent radiation power (NEP) is significantly improved. An additionally structured thin NiCr absorber layer increases the radiation absorption and realizes an uniform spectral behavior. The thermal crosstalk between elements is significantly reduced by isolation trenches, which are also produced by ion beam etching. These trenches allow the use of linear PYROSENS arrays even at low modulation frequency (e.g. 10 Hz). This leads to very low NEP values, which means particularly good signal-to-noise ratios.<\/p>\n<p>On the basis of these advanced arrays, very compact and sensitive dispersive sensor systems can be built in combination with linear variable filters.<\/p>\n<p>For more information, please visit <a href=\"https:\/\/www.dias-infrared.com\" target=\"_blank\" rel=\"noopener\">https:\/\/www.dias-infrared.com<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pyroelectric linear arrays PYROSENS from DIAS Infrared are perfectly suited for use in dispersive sensor systems for the analysis of chemical substances.
