UV-Vis-NIR, Fluorescence and Raman Spectroscopy of Microscopic Samples

The 20/30 PV™ microspectrophotometer is suitable for taking images and spectra of microscopic samples by reflectance, UV-visible NIR absorbance, fluorescence and Raman polarization.

The novel 20/30 PV™ is a highly sophisticated instrument from CRAIC Technologies.  It includes the latest technology in spectroscopy, optics and software to offer excellent performance with high speed and capabilities.  This instrument is the cutting edge of UV-visible NIR and Raman micro-spectroscopy featuring the convenience for which CRAIC instruments are known.

The 20/30 PV™ microspectrophotometer integrates the advanced technologies to enable the user to measure UV-visible-NIR range transmission, absorbance, reflectance, Raman, emission and fluorescence spectra of sample areas smaller than a micron across. It is even possible to determine the thickness of color spaces and thin films.

While acquiring microspectra, the sample may be seen with high-resolution digital imaging in the deep UV, in the near infrared or in color. The 20/30 PV system is easy to use and includes improvements in the instrument ergonomics to software to automation.

The 20/30 PV™ microspectrophotometer is easy to use, the measurements are non-destructive and the spectral data is unmatched.

Which issues were the 20/30 PV™ microspectrophotometer developed to address?

The 20/30 PV™ was designed to acquire spectra of microscopic samples and sample volumes.  It was developed as a precision research-grade instrument and is currently in use in many laboratories around the world. It is used in the characterization of novel materials and the study of such phenomena as surface plasmon resonance, different forms of carbon nanotubes and graphene, and a host of other projects including the development of novel thin films to be used for semiconductors and photovoltaics.
