Raman spectroscopy with a microscope!

Optical microscopes are routinely found in a wide variety of laboratories, but they are often only used as a magnifying glass to allow the user to better see the sample. But when CRAIC Technologies adds a laser and a Raman spectrometer, along with an advanced optical interface, you can do so much more! CRAIC Raman spectrometers are designed to measure Raman spectra of microscopic samples or microscopic areas of larger objects. While a standard Raman spectrometer is designed to measure samples on the order of 1 x 1 centimeters, the Micro Raman spectrometer is able to measure samples on the order of 1 x 1 micrometers...much smaller than the thickness of a human hair. The Apollo Raman systems are modular units that are installed on an upright optical microscopes to add Raman spectroscopy capabilities. With CRAIC Technologies products, you can acquire high quality Raman spectra of even sub-micron samples rapidly, non-destructively and with ease.

As shown in the diagram on the right, the Apollo Raman module is integrated with the frame of an upright optical microscope.  The module includes the lasers, the Raman spectrometer and integration optics.  The laser illuminates the sample and the Raman spectrometer measures the light that is collected by the objective and focused onto the Raman spectrometer entrance aperture. 

Of course, CRAIC micro Raman spectrometers can also do much more.  They can also be configured to measure UV-VIS-NIR microspectra™ in transmission, reflectance, fluorescence and photoluminescence.  They are also capable of microspot thin film thickness and colorimetry measurements.
