The MCS FLEX family of UV-VIS-NIR high-end spectrometers features a central, exclusive aluminum alloy housing for outstanding thermal stability and high repeatability. The aberration-corrected grating, the cross-section converter and the detector are all permanently connected via the central housing, ensuring a robust design and reliability.
Central body: The central body of the MCS FLEX spectrometers consists of a special aluminum alloy to ensure thermal stability (expansion coefficient ~ 13E-6).
Gratings: The gratings of the MCS FLEX family are holographic blazed/ion-etched imaging aberration-corrected flat-field concave gratings for optimized efficiency and best stray light performance. The concave grating, the unique optical component in the design, plays two major roles: the dispersion of light and its focusing onto the linear sensor.
Cross-section converters: A fiber bundle cross-section converter further optimizes signal collection. The linear arrangement of the individual fibers forms the entrance slit (slit height h is determined by the number of individual fibers; the slit width w is determined by the core diameter). The slit is adjusted to the pixel size of the detector used and to the imaging dispersion properties of the flat-field grating, enabling light intensities to reach the theoretical limit. The cross-section converter is an integral part of the spectrometer design, ensuring excellent stability.
Sensors: The MCS FLEX series is offered with high-end CCD and PDA sensors to take full advantage of the spectrometer platform optical performance.
The TE-cooled S7031-1006Q back-thinned CCD offers high QE across the whole UV-VIS-NIR spectral range, and delivers an outstanding full well (up to 1Me-) with very low readout noise. This scientific-grade CCD guarantees the most accurate spectroscopy measurements.
The S3904-1024 linear PDA, best suited for absorbance measurements, delivers high full well (>250Me-) and low readout noise, ensuring best dynamic range for demanding applications.
