Raman Microscopy


DeltaNu ExamineR

Raman Microscope

Raman microscopy is an information-rich way to characterise the samples in life sciences, geology, nanotechnology, semiconductor, forensic science and many other applications where accurate chemical identification is required. DeltaNu offers you a high performance Raman microscope ExamineR™ at an affordable price.

ExamineR™ adopts the research quality upright microscope BX51 Olympus and offers outstanding imaging and spetral characerising performance. Inverted microscopes, such as IX71 Olympus, or many other makes, such as Nikon and Zeiss, can all adapt to ExamineR.

Two software options are available for the ExamineR:

  • NuSpec™: instrument control software for data acquisition and library development
  • NuImage™: mapping software that features intuitive map building and image overlays with false colour maps created from collected Raman spectra.

The ExamineR™ is a modular system that allows you to switch easily among different wavelength modules - 532 nm, 785 nm and 1064 nm - without any tedious swapping procedures. Not only does this free space design eliminates the time wasted to swap the lasers, filters and gratings, but it also minimises the desk space required.
