High-performance for wavelengths in infrared

For over 35 years Instrument Systems has been a hallmark of excellence in light measurement technology. This is especially true for the globally recognized high-end spectroradiometers. They are the key component for a wide range of photometric tasks in diverse, innovative applications. All radiometric, photometric and colorimetric properties are calculated from the spectral data of the spectroradiometer with the aid of extensive software suites such as SpecWin Pro. Their precision and accuracy are thus especially important for exact readings.

The new CAS 140D IR also guarantees this 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 CAS 140D IR contains a new electronic platform that enables faster processing of measurements: the minimum possible integration time has been reduced from 10 ms to 4 ms, the total scanning time for a measurement from 16 ms to 10 ms. The advantages for the user lie in higher productivity due to shorter measuring times, accompanied by greater precision and repeatability. As a supplement to the broadband model (780–1700 nm) high-resolution devices are available specially for the measurement of narrow-band laser diodes such as VCSEL: e.g. 1300–1440 nm with a spectral resolution of 0.75 nm.

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 IR.
