The Leica S6 D Greenough stereo microscope with 6.3:1 zoom and integrated video/photo port allows easy, fast documentation for assembly, quality control, OEM and research applications. Adjustable zoom stops allows fast, easy, repeatabl

e measurements and inspections. The large field of view up to 36.5 mm and high depth of field, reduces sample handling and improves inspection times. Ergonomic 38° viewing angle provides comfort, which helps increase productivity, reduce fatigue related inspection errors and acquire precise positioning while working with incident or transmitted light. The integrated documentation port allows to connect digital cameras.



Within the POIG 1.1.2 and POIG 2.2 Projects, Raman Imaging Group conducts research on the following spectrometers:

Raman spectrometer Witec alpha300 equipped in:
• Confocal microscope (CM)
• Scanning Near-field Optical Microscope (SNOM)Raman spectrometer Witec alpha300
• Atomic Force Microscope (AFM)
• EMCCD-detector for Ultrafast Confocal Raman Imaging

The design of the alpha300 S Scanning Near-field Optical Microscope features a Confocal Microscope (CM), a Scanning Near-Field Optical Microscope (SNOM) and an Atomic Force Microscope (AFM) in a single instrument. By simply rotating the objective turret, the user can choose from among Confocal Microscopy, SNOM or AFM. All standard optical modes such as transmission, reflection and fluorescence are available. When using AFM-cantilever tips, all standard AFM modes are readily accessible. The alpha300 S has a modular design, is very flexible and can be easily configured for a wide variety of applications and individual requirements. The Confocal Raman Imaging Upgrade option for the WITec alpha300 S Scanning Near-field Optical Microscope allows the acquisition of Raman images from chemical investigations to be linked to the AFM topographic information from the same sample area. No transferring or touching of the sample is required as the two modes are easily accessible by just rotating the microscope turret. Even simultaneous AFM-Raman data acquisition is possible.

WITec Alpha Cart a prototype of a portable WITec system working with hand handle fiber optic probe. Due to its novel design and application of the probe with objective, the obtained Raman spectra are characterized by the increased signal to noise ratio and higher intensity of Raman signals. The system is equipped with a lens-based spectrograph, a low-noise CCD detector and an air cooled solid state laser with an excitation wavelength of 532 nm. Laser light is provided via a photonic fiber and focused onto the sample with a probe ending with an objective enabling higher spatial resolution.

We also possess two other fiber optic probes from InPhotonics company. They cooperate with 532 and 785 nm lasers and can be combined with our WITec systems. The optics, including the bandpass filter, beam splitter, lens, mirror and longpass filter are integrated in the compact probe head which is connected to the 105 μm excitation and the 200 μm collection fibers. The probes have a focal distance of ca. 7.5 mm and the laser focus diameter is approximately 160 μm.

ROA spectrometer ChiralRAMAN-2X BioTools Inc.

ROA is a form of Vibrational Optical Activity (VOA) that is complementary to Vibrational Circular Dichroism(VCD) in the same way that Raman spectroscopy is complementary to IR spectroscopy. ROA is defined as the difference in Raman intensity for left (L)- minus right (R)-circularly polarized incident and/or scattered radiation in chiral molecules. It combines the structural specificity of vibrational spectroscopy with the stero-sensitivity of chiral detection.
