The neaSNOM microscope with it’s imaging and nano-FTIR mode is the most useful research instrument in years, bringing genuinely new insights.
We were looking for a flexible research tool capable of characterizing our energy storage materials at the nanoscale. neaSNOM proofed to be the system with the highest spatial resolution in infrared imaging and spectroscopy and brings us substantial new insights for our research.
A unique advantage of the neaSNOM microscope is that it can be applied to many fields of scientific research such as Chemistry, Semiconductor Technology, Polymer Science and even Life-Science.
I needed a flexible experimental platform with a high degree of optical access. The highly modular design of neaSNOM provides an ideal foundation for the development of my own experiments on top of it.
As a near-field expert I was quickly convinced that neaSNOM is the only optical AFM microscope completely satisfying the needs of demanding near-field experiments. It’s the best comercially available technology and in addition really easy to use.
As a newcomer to the near-field optics I am very grateful for the prompt and competent support provided by neaspec’s experts.
neaspec provides an ideal and reliable near-field optical microscope. Their expertise has proved invaluable in setting up my experiments.
After many years of research and development in near-field microscopy, we finally made our dream come true to perform infrared imaging & spectroscopy at the nanoscale. With neaSNOM we can additionally realize Raman, fluorescence and non-linear nano-spectroscopy.
Developed by the s-SNOM experts, the neaSNOM microsocope is the ideal tool for our demanding applications. We work on characterizing opto-electronic devices like LEDs, transistors based on GaN and SiC as well as nanocomposites in e.g. textile fibers.
