Birefringence means double refraction. It is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light . [ 1 ] These optically anisotropic materials are described as birefringent or birefractive .
If the birefringence is known, then the thickness, t, of the sample can be determined; If the thickness is known, then the birefringence of the sample can be determined; As the order of the optical path difference increases, then it is more likely that more wavelengths of light will be removed from the spectrum.
In order for a molecule (or crystal) to exhibit circular birefringence and circular dichroism, it must be distinguishable from its mirror image.An object that cannot be superimposed on its mirror image is said to be chiral, and optical rotatory dispersion and circular dichroism are known as chiroptical properties.
Polarizing microscope operating principle Depiction of internal organs of a midge larva via birefringence and polarized light microscopy. Polarized light microscopy can mean any of a number of optical microscopy techniques involving polarized light. Simple techniques include illumination of the sample with polarized light.
A conoscopic interference pattern or interference figure is a pattern of birefringent colours crossed by dark bands (or isogyres), which can be produced using a geological petrographic microscope for the purposes of mineral identification and investigation of mineral optical and chemical properties.
Optical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials. Circular birefringence and circular dichroism are the manifestations of optical activity.
When values of birefingence are very high, the property is termed giant birefringence which more generically is called giant optical anisotropy. Values for giant birefringence exceed 0.3. Values for giant birefringence exceed 0.3.
Shows how the X-ray polarization plane changes during an X-ray birefringence imaging experiment. X‑ray birefringence imaging [1] (XBI) can be considered the X‑ray analogue of the polarizing optical microscope. XBI uses linearly polarized X-rays with an energy tuned to an elemental absorption edge. The tuned X-rays interact solely with the ...
