  • 508 Perfect Vision Spectrophotometer
Oct 2013
Elliot Scientific Ltd.Request Info
HARPENDEN, England, Oct. 16, 2013 — The new 508 Perfect Vision by Craic Technologies, offered by Elliot Scientific, adds UV-VIS-NIR spectrophotometry and imaging to legacy microscopes for numerous nondestructive laboratory and manufacturing microanalysis applications. These include new materials characterization; measurement of surface plasmon resonance, graphene and vitrinite reflectance of coal; and colorimetric and relative intensity mapping of flat panel displays.

Designed to be added to an open photoport of a microscope or probe station, the device features Craic Technologies’ proprietary Lightblades spectrophotometer and optical interface technologies. It can acquire 8-megapixel high-resolution color images and the spectra of microscopic sample areas by absorbance, reflectance, polarization, luminescence and fluorescence.

The natural log of the ratio of absorbed intensity over the total intensity which gives a constant value assuming a stable volume as well as energy. In optical physics the absorbance may be defined as the absorption cross section multiplied by the absorbing material length.
The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
See fluorescence; phosphorescence.
With respect to light radiation, the restriction of the vibrations of the magnetic or electric field vector to a single plane. In a beam of electromagnetic radiation, the polarization direction is the direction of the electric field vector (with no distinction between positive and negative as the field oscillates back and forth). The polarization vector is always in the plane at right angles to the beam direction. Near some given stationary point in space the polarization direction in the beam...
The ratio of reflected flux to incident flux. Unless otherwise specified, the total reflectance is meant; it is sometimes convenient to divide this into the sum of the specular and the diffuse reflectance.
An instrument for measuring spectral transmittance or reflectance.
