  • Exceptional accuracy over the entire travel and scan range (0.03 % linearity)

Further information

While long recognized as the state-of-the-art imaging system, ongoing development resulting from WITec's innovative spirit has kept the alpha300 R at the forefront of Raman microscopy and set the benchmark in terms of imaging capability as well as spectral quality, spatial resolution, ease-of-use and compatibility with other measurement techniques. The flexibility of the alpha300 R series allows the system adapt to all requirements, combine different imaging techniques and to evolve to meet new or expanded needs. The alpha300 R offers the following extensions: alpha300 R+ for automated measurements:
  • Automated motorized sample positioner in x-, y-, and z-direction, 25 mm travel range (50 mm travel range optional)
  • Automated confocal Raman Imaging (25 x 25 mm; optional 50 x 50 mm)
  • Automated multi-area and multi-point measurements
  • 2D and 3D Raman mapping
  • Raman depth profiling
  • Autofocus

Applications

Life Science From measurements in liquids to solid samples or soft tissues in life science varied samples are analyzed on a regular basis. With their convenient handling and versatile analytical capabilities the flexible WITec imaging systems provide the opportunity to adjust the imaging technique to changing requirements and are particularly well-suited for life science.
Pharmaceutics, cosmetics The development and production of drug delivery systems requires efficient and reliable control mechanisms to ensure the quality of the final products. These products can vary widely in composition and application. Therefore analytical tools such as the WITec imaging systems that provide both comprehensive chemical characterization and the flexibility to adjust the method to the investigated specimen are preferred in pharmaceutical research.
Materials science Materials science is a diverse field including the development and testing of new substances, as well as the refinement of manufacturing processes and quality control for existing products. WITec imaging systems are particularly well-suited for comprehensive sample analyses in materials science and provide the opportunity to acquire a thorough knowledge of the sample surface morphology and chemical composition.
Geoscience WITec confocal Raman imaging systems are excellent analytical tools for the comprehensive investigation of geological samples, such as the identification and characterization of minerals, or in the observation of mineral phase transitions in high and ultra-high pressure/temperature experiments.
Polymers WITec imaging systems enable comprehensive sample analysis that provides a thorough characterization of the physical and chemical properties of the polymers on the nanometer scale.
Nano-Carbon and graphene Nano-carbon materials such as graphene or carbon nano-tubes show immense promise in many applications such as transistors, sensors, and optoelectronics. Flexible and adaptive analytical methods can support effective investigation and accelerate progress in nano-carbon & graphene research and development.
