The WITec apyron imaging system has been developed to overcome the gap between ease-of-use and ultimate capability in Raman imaging. It is ideal for multi-user/industrial labs, Raman newcomers with advanced imaging requirements and established Raman spectroscopists.
apyron sets the benchmark for automated Raman imaging systems offering: outstanding spectral and spatial resolution, ultra-fast acquisition times, and exceptional signal sensitivity in combination with automated system configurations and intuitive measurement procedures.
- TruePower: automated absolute laser power determination in mW
- Automated laser wavelength selection and spectrometer adjustment
- Ultra-high throughput spectrometers for unprecedented spectral resolution
- Carbon tetrachloride in an alkane-water-oil emulsion
Figure 1: Carbon tetrachloride is quite often used as a reference sample in order to determine the performance of a Raman spectrometer in terms of spectral resolution. The characteristic peak at 460 rel. 1/cm should be clearly resolvable at room temperature. Due to its ultra-high optical throughput the apyron is the first system on the market to allow for fast Raman imaging while simultaneously maintaining the ability to resolve this peak.
Figure 2: White-light microscopy and color-coded Raman image overlay of a squashed banana pulp sample. This experiment was performed in the WITec application lab to show the capabilities of the new system. In food technology it is important to know as much as possible on the distribution of food components such as starch and carotene. The measurement shows starch particles agglomerating in the pulp-cells.
The Raman image was acquired with an apyron attached to the 600 mm focal length UHTS 600 spectrometer system (grating: 300 g/mm) to provide the highest spectral performance. Red: Beta-carotene-rich areas, Green: Starch, Blue: Water
