Request InfoInstrument Systems GmbHInstrument Systems GmbH has introduced the CAS 140B models of array spectrometers. Supplied with diode array, CCD and InGaAs detectors, these devices are suited for spectroradiometry and photometry applications. Users can choose from a diode array or CCD with 1024 pixels and operation from 190 to 1100 nm; the InGaAs detector has 256 pixels and operates in the 800- to 1650-nm range. Standard cooling is down to 0 °C and the flat-field spectrograph has a 140-mm focal length. Spectral resolution is from 2 to 12 nm, depending on the selected entry slit. A 15-bit A/D converter is supplied.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 12/13/2022InGaAs Photodiode DetectorsMarktech Optoelectronics' lineup of advanced InGaAs photodiode detectors consists of several detector families or series based on their spectral sensitivity ranges.
