For Measurement Applications
PYROSENS Single-Element and Mult i-Channel Detectors
The pyroelectric single-element and multi-channel infrared detectors fromDIAS Infrared GmbH are designed for use in gas analysis, spectroscopy,
pyrometry and security engineering applications.
Very high values of specific detectivity D* (109 cm √Hz/W) are achieved by using modern ion beam etching technology for extremely thin elements. The great variety of infrared sensor constructions makes it possible to realize custom-made solutions for both small and large quantities with an excellent price-performance payoff.
Further features of our single-element and multi-channel detectors:– Detector elements made from Lithium Tantalate– Extremely low noise– Low microphony, low temperature dependence– Very good long-term stability– Voltage or current mode– Custom-designed IR filters– Optional with absorber or silver black, optional with absorber or silver black– Up to 4 spectral channels per detector– Individual element geometries– Different package types
Our detectors are available in different types:LT – Standard typesLTA– Types with increased absorptionLTS – Types with silver blackLTI – Ion beam etched, max detectivity
IR filter
• Coated silicon or germanium as infrared window
• Broad band windows (>1.3 µm) or special filters
• Customized filters and integrated optics
