Raman Spectrometer

The CRAIC Technologies™ Raman spectrometer is used to measure Raman spectra of microscopic samples or microscopic areas of larger objects.  The fully integrated CRAIC Apollo™ Raman spectrometer has been built and optimized for microspectroscopy and is capable of measuring the Raman spectra of microscopic samples.  

The CRAIC Technologies™ Raman spectrometer is a purpose-built system that allows you to analyze Raman microspectra™ non-destructively and with no sample contact.  Capable of analyzing even microscopic areas, they are also capable of color digital imaging.  Designed for ease-of-use, they are durable instruments designed for microscale Raman spectroscopy.

The contrast ratio of individual pixels and microdisplays can be measured and compared using microspectrometers.

Flat panel displays consist of a series of colored lighted areas arranged in a pattern and can only be readily viewed with magnifying optics.  Due to the high resolution of flat panel displays, they are manufactured with hundreds of rows of microscopic "pixels" on a surface.  Generally, these pixels are red, blue and green though pixels with other colors are also made...for example the latest four color systems also incorporate yellow pixels.

One aspect of display quality control consists of making sure that the contrast ratio of each pixel does not vary across the entire display.  For example, all the green pixels should have the same contrast ratio no matter where they are positioned in the display. 

Microspectrometers are able to gather contrast ratio data from single pixels and from groups of pixels (if you are interested in mura).  Additionally, microspectrometers are also able to map the relative intensity variation within even a single pixel!  This leads to a new level of precision for improved displays.

The way a microspectrometer works is that spectrophotometer entrance aperture is placed over the pixel or pixels in questions.  The black square in Figure 1 is an example.  The spectra is then acquired and will look something like the three spectra in Figure 2.  Using the Lambdafire™ software, the intensity data is compared with measurements of other pixels to show that the brightness of each sampled area is within the manufacturing parameters.  A high resolution map of the relative intensities can then be generated.

Chromaticity is used in display development to optimize the colors.  Quality control consists of making sure that the color of each of the pixels does not vary across the entire display.  For example, all the green pixels should have the same shade of green.

Microspectrometers are able to gather microcolorimetric data from single pixels and from groups of pixels (if you are interested in mura).  Additionally, microspectrometers are also able to map the microcolorimetric variation within even a single pixel!  This leads to a new level of color precision for improved displays.

The way a microspectrometer works is that spectrophotometer entrance aperture is placed over the pixel or pixels in questions.  The black square in Figure 1 is an example.  The spectra is then acquired and will look something like of the spectra in Figure 2.  Using the CRAIC ColorPro™ software, microcolorimetric data is generated.  This can be compared with measurements of other pixels to show that the color of each sampled area is within the manufacturing parameters.
