Infrared filter - Import export

The premium dual channel thermopile has been specifically designed for demanding measurement applications for the analysis of N2O (nitrous oxide) in environments from -20 to 85 °C. It achieves an exceptionally high detectivity of up to 6.27*10^8 cm√Hz/W and a sensitivity of up to 171 V/W. This signal quality is comparable to pyroelectric detectors. The infrared filter with a CWL of 4525 ± 20 nm and a HBW of 83 ± 6 nm is precisely matched to the optical characteristics of the target gas. Medical technology, especially patient and anesthetic gas monitoring, are typical application fields for the MTS2SENS200 nitrous oxide. The integrated thermistor for reference temperature determination and an additional reference channel (CWL: 3910 ± 28, HBW: 70 ± 10 nm) complete the detector. The dual detector MTS2SENS200 nitrous oxide is based in the core on 2 chips with 200 bismuth-antimony/antimony thermocouples each.

This 2 channel premium pyrodetector offers an optimal performance for the measurement of carbon compounds (CxHy) through the narrowband infrared filter with a CWL of 3400 ± 20 nm and a HBW of 140 ± 20 nm as well as an additional reference channel (CWL: 3910 ± 28, HBW: 70 ± 10 nm). The particularly high detectivity of up to 4.0*10^8 cm√Hz/W as well as the very high sensitivity of up to 200000 V/W guarantee precise and long-term stable measurement results. The pyroelectric detector allows demanding applications in gas measurement and gas analysis in various industries such as aerospace, medical or industrial process technology. Two detector chips with a ceramic pyroelectric thin film diaphragm form the core of this 2 channel pyroelectric detector. The low microphone effect due to the low membrane mass, the very low temperature dependence and an amplified signal in current modes enhance the measurement signals of the dual IR detector.

2 sensor chips, each with 200 bismuth-antimony/antimony thermopairs, form the basis of this thermopile detector. Incident IR radiation creates thermal diffusion currents of the two different metals (Seebeck effect). The signal strength of the highly sensitive IR sensor is comparable to that of a pyro detector: high detectivity up to 6.27*10^8 cm√Hz/W and high sensitivity up to 171 V/W (detector with the filling gas Krypton in the TO housing). The infrared filter windows are ideal in their optical characteristics for the analysis of flouranes with a CWL of 8620 ± 45 nm and a HBW of 540 ± 45 nm. The interference absorber, an integrated thermistor for reference temperature determination and the reference channel (CWL: 5060 ± 25, HBW: 100 ± 15 nm) are further important features for reliable measurements in demanding medical applications. The MTS2SENS200 flourane provides reliable measurements in environments between -20 and 85 °C, e.g. for anesthetic gas monitoring.

The high detectivity up to 4.0*10^8 cm√Hz/W as well as the high sensitivity up to 200000 V/W characterize the MPS2SENS flourane. The optical characteristics of the infrared filter windows perfectly suit the analysis of flouranes (CWL of 8620 ± 45 nm, HBW of 540 ± 45 nm, reference channel with CWL: 5060 ± 25, HBW: 100 ± 15 nm). The MPS2SENS sulfur dioxide provides reliable readings in environments between -20 and 85 °C for NDIR gas measurement in medical applications, e.g. anesthetic gas monitoring. The pyroelectric detector has 2 chips with a thin film CPM membrane in the core. (CPM: Ceramic Pyroelectrical Material). Other key product features for long-term use in demanding applications: wide spectral sensitivity 2 - 15 µm (optimized from 3 - 5 µm), high sensitivity with a modulation frequency of up to 100 Hz, low microphone effect due to the low membrane mass, very low temperature dependence, amplified signal in current mode.

This premium pyroelectric quad detector is tailored for measurement applications for the analysis of nitrogen oxides (NOX) in environments from -20 to 85 °C. The filters determine the infrared detection of the following gases: water vapor (H2O) (CWL: 6580 ± 40, HBW: ± 35 nm), nitric oxide (NO) (CWL: 5300 ± 30, HBW: ± 20 nm), sulfur dioxide (SO2) (CWL: 7300 ± 50, HBW: 180 ± 20 nm) and an embedded reference channel (CWL: 5060 ± 25, HBW: 100 ± 15 nm). The four-channel IR pyrodetector achieves a high detectivity of up to 4.0*10^8 cm√Hz/W and sensitivity of up to 200000 V/W. The MPS4SENS NOX provides reliable measurement values in ambient temperatures between -20 and 85 °C, e.g. for industrial gas measurement or process analysis in various industry and manufacturing areas, such as chemical, textile, environmental technology, recycling or exhaust gas technology. Micro-Hybrid is the only manufacturer of pyroelectric 4-channel detectors with a high performance membrane in a TO39 package.
