Gain entrance to the Raman world today – Stay flexible for emerging challenges tomorrow

 

 

access is a micro-Raman single-spot analysis and mapping microscope. It was specifically engineered for budget-conscious customers with high demands on instrument performance. Its outstanding spectral quality, optical throughput and signal sensitivity are ensured by well-established WITec optical elements.

The high-quality microscope setup of the access is also the basis for its full upgradability. Whenever needed, access can be easily and quickly adapted to new requirements. Customized solutions for e.g. scan stages, spectrometers, cameras and lasers can be added and even advanced Raman techniques can be integrated.

So over time, with an access microscope as a starting point, one could build up a WITec high-end instrument to conquer the Raman world. With this continuity inherent in our product line, access enables our customers to keep pace with the evolving state of the art.
