CAS 140D IR The new reference array spectrometer for IR measurements Key features at a glance y Highly accurate infrared (IR) measurements y High-performance InGaAs sensor with greatly improved optical bench design y High signal sensitivity y ow stray light L y Fast electronics The new CAS 140D IR guarantees proven high measurement accuracy and reliability. It also promises significantly better performance for wavelengths in the infrared range than its predecessor CAS 140CT IR. Thanks to a new design of the optical architecture, throughput has been increased by up to 70 %. The stray light proportion has again been significantly reduced. In addition, the electronic platform of the CAS 140D IR enables faster processing of measurements: the minimum possible integration time has been reduced from 10 ms to 1 ms, the total scanning time for a measurement from 16 ms to 9 ms. The advantages \\ TECHNICAL SPECIFICATIONS Model Wavelength range Pixel number Spectral resolution Datapoint interval Wavelength accuracy Integration time Shortest duration SOT to EOT Sensor dynamic range for the user lie in higher productivity due to shorter measuring times, accompanied by greater precision and repeatability. Like all Instrument Systems spectrometers, the infrared models feature calibration traceable to PTB or NIST. With a trigger box, various different CAS models can be combined to a MultiCAS system and complex spectral measurements run parallel over an extremely wide wavelength range. In the right combination with 2D imaging colorimeters, IR cameras, integrating spheres or goniometer systems they precisely and reliably perform individual customer tasks for wavelength ranges from UV to
