MMS Spectrometer design


ZEISS MMS modules feature a round-to-slit fiber converter for maximum throughput. The aberration-corrected holographic gratings ensure high diffraction efficiency and ultra-low stray light. MMS modules have linear photodiode arrays with large active area and very low noise, delivering highest SNR. Two options are available: S3904-256Q for high UV sensitivity or S8381-256Q for high NIR sensitivity.

Operating electronics & software for ZEISS spectrometers

  • Operating electronics for spectrometers from ZEISS

    ZEISS offers custom tailored operating electronics for our MMS spectrometer modules. This includes the preamplifier, front-end and USB/Ethernet interface electronics. Besides, different software tools are provided: the acquisition & analysis software ASPECT PLUS or software development kits (SDK) for perfect integration in industrial environments.

  • Preamplifier electronics

    The preamplifier and the front end electronics are matched to the spectrometer module. Its task is the amplification of the low analog output signals of the detector array and the minimizing possible analog signal interference. The preamplifier board is integrated into the spectrometer housing. Furthermore, ZEISS offers a small-footprint MMS module without preamplifier board for OEM customers using their own electronics. We offer a cost-effective preamplifier board suitable for 15-bit front end electronics with 200 kpixel/s readout as well as fast preamplifier electronics suitable for 16-bit front end electronics with 1 Mpixel/s readout.

  • Front end electronics

    The front end electronics act as an adapter between the preamplifier and the interface electronics of a spectrometer system. They preprocesses the amplified analog video signal and perform the analog to digital conversion. The digitized values are then forwarded as a byte sequential data stream for the interface electronics. High dynamics and signal stability in the configurations used are achieved thanks to quartz-precision timing and integrated filtering of supply voltages. ZEISS MMS spectrometers are available with fast 16-bit front end electronics with 1 Mpixel/s readout or cost-sensitive 15-bit front end electronics with 200 kpixel/s readout speed.

  • High-speed interface electronics

    ZEISS provides high-speed digital spectral data acquisition controllers with PCI, USB 2.0/3.0 and Ethernet interfaces for PC communication. The interface electronics board thereby acts as a connecting piece between the front end electronics and the PC. The 10/100 Base-T Ethernet interface is recommended for long distance communication and is ideally suited for distributed systems and decentralized monitoring.

  • ZEISS software solutions

    ZEISS provides different software tools to meet spectroscopic analysis and automation needs. A convenient solution is provided by the ready-to-use ASPECT PLUS software package. Running under MS Windows, it easily enables the acquisition and analysis of spectral data. Furthermore, we offer Software Development Kits (SDK) consisting of programming libraries allowing maximum flexibility for user-specific applications.

    The Aspect PLUS software for acquisition and analysis of spectra with clear graphical interface runs on the latest Window versions and controls ZEISS spectrometers. Functions as spectra display, data handling routines, kinetics and calculation of concentrations or color and film-thickness evaluation modules are implemented.

    OSIS SDK is a software development kit to support development of software applications for ZEISS spectrometers. There are several ways to create an application from scratch using one of the provided templates. It is also possible to add OSIS SDK to your existing projects using NuGet packages. The 32/64 bit SDK and the underlying OSIS Framework are based on .NET Standard 2.0 and are not limited to a specific platform or architecture.
