CRAIC Technologies provides superior UV-visible-NIR microanalysis solutions including Microspectrophotometer & Microspectrometer

Multi-Functional Microspectrophotometer Featuring UV-Visible-NIR, Photoluminescence, Raman and Polarization Microspectra™

San Dimas, CA (January 17, 2018) – CRAIC Technologies, the world leading innovator of microspectroscopy solutions, has added Raman microspectroscopy to its flagship product: the 20/30 Perfect Vision™ microspectrophotometer . Users of the 20/30 PV™ now have the ability to acquire Raman spectra by integrating the new Apollo II™ Raman microspectrometer with the 20/30 PV™.  Together, these two systems offer multiple laser wavelengths, in addition to UV-visible-NIR absorbance, reflectance, fluorescence and emission microspectra™. The 20/30 PV™ is able to acquire all these types of spectra micron scale samples rapidly and easily. Better yet, the 20/30 PV™ is able to acquire all these spectra from the same area because it features CRAIC Technologies proprietary optical aperturing technology. Additionally, the 20/30 PV™ features the ability to acquire images of these same microscopic samples in the UV, visible and NIR regions. The applications for such a multi-purpose instrument are numerous. For example, the 20/30 PV™ is used to develop the latest advanced materials, such as graphene and carbon nanotubes, to studying various types of biological samples, including lignins and nanocrystalline cellulose, to the analysis of forensic samples and the measurement of thin film thickness in the semiconductor industry. Giving this instrument the ability to analyze the Raman spectra of microscopic samples in addition to UV-visible-NIR and fluorescence microspectroscopy makes the 20/30 PV™ the cutting-edge micro-analysis tool for any laboratory or manufacturing facility.

“CRAIC Technologies has long been an innovator in the field of UV-visible-NIR microanalysis. We have helped to advance the field of microscale analysis by constantly developing new instrumentation as well as with research and teaching. Adding Raman microspectroscopy capabilities to our leading edge 20/30 PV™ microspectrophotometer makes it the ideal tool for the laboratory or process environment as it packs so many capabilities into one unique tool” states Dr. Paul Martin, President of CRAIC Technologies. “The 20/30 PV™ is now able to acquire vibrational spectra in addition to UV-visible-NIR spectra and images. And using CRAIC Technologies proprietary optical technology, the Raman, UV-visible-NIR and luminescence spectra are all from the same area. The ability to acquire spectra using multiple techniques and of the same microscopic target area represents a strong advantage for the 20/30 PV™ microspectrophotometer.”

The 20/30 PV™ microspectrophotometer is a self-contained unit that features advanced UV-visible-NIR light sources, solid state lasers, true UV-visible-NIR microscopy, sensitive Lightblades™ spectrometers and sophisticated Lambdafire™ spectral and imaging software. Raman microspectroscopy is added with the Apollo™ Raman microspectroscopy packages. The Apollo II™ is a self contained package including laser, spectrometer and hardware that is integrated with the cutting-edge 20/30 PV™ microspectrophotometer, giving you multiple methods to analyze microscopic samples rapidly and easily. With its Raman, UV-visible-NIR spectroscopic and imaging capabilities, durable design, ease-of-use and the experience of CRAIC Technologies in microanalysis, the 20/30™ microspectrophotometer is more than just a scientific instrument…it is a solution to your most challenging analytical questions.

UV-visible-NIR spectroscopy

A UV-visible-NIR spectrophotometer, such as used in CRAIC Technologies microspectrophotometers, measures the intensity of electromagnetic energy wavelength by wavelength. 

How does a Spectrophotometer Work?

UV-visible-NIR spectrophotometer

The spectrophotometer is an optical instrument for measuring the intensity of light relative to wavelength. Electromagnetic energy, collected from the sample, enters the device through the aperture (yellow line) and is separated into its component wavelengths by the holographic grating. Simply put, the grating acts to separate each color from the white light.  The separated light is then focused onto a CCD array detector where the intensity of each wavelength (or each color if in the visible region) is then measured by a pixel of the array. The CCD is then read-off to a computer and the result is a spectrum which displays the intensity of each wavelength of light.

An example would be a spectral measurement of the visible range which we perceive of as color.  White light would enter the monochromator and be separated into a rainbow of each color.  This rainbow, with blue light on one end and red on the other, would be focused on to the CCD.  Each pixel of the CCD would then measure the intensity of a color.  The results would be a spectrum such as the one shown below.  As shown, the blue pixels emit blue light, the green pixels emit in the green portion of the spectrum and the red pixels emit red light.

CRAIC Technologies builds microspectrophotometers.  These devices integrate the spectrophotometer with a microscope to enable one to measure the spectra but of microscopic sample areas.  Microspectrophotometers are also used to measure fluorescence, photoluminescence, thin film thickness measurements, microcolorimetry, for imaging and much more.  Microspectrophotometers are used for diverse applications such as colorimetry of pixels on flat panel displays, reflectometry of vitrinite coal and thin film thickness measurements.

Why use a Spectrophotometer?

What a Spectrophotometer can reveal

The spectrophotometer allows the scientist or engineer to acquire spectra of by shining white light on a sample and measuring the light that is returned from the sample.  With this non-destructive technique, measurements can be made with light transmitted through the sample, reflected from it or even when the sample is made to emit light by processes such as photoluminescence.  The UV-visible-NIR range is especially important as more substances...even colorless ones...absorb in the UV than in the visible and infrared regions. Therefore, a UV -visible-NIR range spectrophotometer is very useful for analysis of most samples for any application.

Spectrophotometers are employed in many different fields and are found in both scientific laboratories and production facilities. In the production environment, for example, they are used for quality control of everything from clothing to the emission of light when producing LEDs.   Spectrophotometers are used by analytical laboratories to identify and quantify microscopic samples ranging from the kinetics, matching colors, the qualification of gems and minerals, the determination of the color of ink or paint by a process chemist. As such, the spectrometer is a highly flexible instrument with many different applications.
