:
The combination of features required for DTU’s research is uniquely provided by the WITec alpha300 apyron, which is the top of the line in WITec’s series Raman imaging microscope. It is an automated 3D Confocal Raman Microscope that is integrated with an Atomic Force Microscope, enabling acquisition of Raman-related chemistry map with detailed topographical features through WITec True Raman surface technology and AFM system. The system is modular and easy to upgrade when more laser excitation sources, spectrometers, stages or accessories are required. The system has been customised to adopt larger samples 50x50mm, which is an excellent working area for construction material characterisation. The system has been coupled with a Top Stage Incubator with CO2 and Humidity Control, and the potential to inject water. The system is equipped with water dipping objectives enabling underwater characterisation. Also, it cover multiple short and long distance objectives (10x,50x,100x), providing opportunities for high resolution imaging and flexibility for specific applications like monitoring heat-generating reactions. Additionally, we require high spatial resolution, better than 350 nm, when using a 532 nm laser, as well as the capability for depth profiling with a resolution better than 900 nm using the same laser. The user interface is a software, WITec Project SEVEN PLUS, offering advanced Raman imaging and SPM data evaluation, with unique functionalities included: ⦁ Additional Features for TrueComponent Analysis: ⦁ Automatic determination of Components based in residual analysis ⦁ Simply add components into your analysis by double clicking any image pixel ⦁ Real-time image refresh for visualization of refined results ⦁ Intuitive Demixing of components by weighted subtraction algorithms ⦁ Multivariate Dataanalysis: Cluster analysis, Principal component analysis (PCA) & Non negative matrix factorization (NMF) ⦁ Advanced fitting tool: Fitting of full 2D/3D datasets ⦁ Data cropping and reduction ⦁ Image correlation & Overlay ⦁ Graph and image repair ⦁ Various filters e.g. Fourier, Anisotropic, Edge, Sharpen, User-Customized. The MSX3201-7010 1 piece WITec Control SEVEN, software license Instrument and experiment control software package with multi-purpose WITec EasyLink Human Interface Device. Functionality (dependent on configuration): · EasyLink Advanced Video Control: Video Autofocus, Auto-Brightness, stepless LED Brightness slider controls · EasyLink Movement and Focus Control: Move around the sample precisely using independent analogue control sticks · All measurement modes accessible in one comprehensive software package · Measurements with all installed techniques (e.g. AFM, Raman) can be applied, controlled simultaneously and are easily correlated · All essential parameters are automatically set when changing between measurement modes · TrueScanTM for exact piezo positioning control even at the fastest scan rates (requires Piezo-Scanner) · Capability of measuring very large data sets, for e.g. image stacks · Automated multispot measurement sequences with the ability to execute complex scripts at every point · Multi-user management including user customizable software configurations for individual measurement pre-configurations While other Raman technology providers also offer high-quality Raman systems, none found capable of providing the required combination of features in a single, modular, upgradeable platform with large-sample handling and the specific environmental capabilities essential for the multidisciplinary projects at DTU Construct. Most alternative solutions were fixed configurations, limiting adaptability for evolving research needs and requiring significant reinvestment for future expansions. The selected system uniquely meets all criteria in a single integrated setup. It combines confocal Raman and AFM in a modular architecture with advanced automation and environmental control, enabling precise correlation between chemical and topographical data for large and heterogeneous material samples. Its compatibility with a wide range of third-party stages and accessories further ensures long-term adaptability. This configuration has been successfully deployed in leading research laboratories for similar applications demonstrating reliability and performance in demanding material science contexts. Based on technical capabilities, upgrade potential, and cost-effectiveness, no alternative supplier could match the full set of required specifications.
