  2. Optical rotatory dispersion - Wikipedia

    en.wikipedia.org/wiki/Optical_rotatory_dispersion

    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. Most biological molecules have one or more chiral centers and undergo enzyme-catalyzed transformations that either maintain or invert the chirality at one or more of these ...

  3. Optical engineering - Wikipedia

    en.wikipedia.org/wiki/Optical_engineering

    Optical engineering is the field of engineering encompassing the physical phenomena and technologies associated with the generation, transmission, manipulation, detection, and utilization of light. [2]

  4. Optical rotation - Wikipedia

    en.wikipedia.org/wiki/Optical_rotation

    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.

  5. Window (optics) - Wikipedia

    en.wikipedia.org/wiki/Window_(optics)

    A flatness test of a float-glass optical window on top of a λ/10 optical flat. The window measures a flatness of 4–6 λ per inch. In optics, a window is an optical element that is transparent to a range of wavelengths, and that has no optical power. Windows may be flat or curved.

  6. Optical path length - Wikipedia

    en.wikipedia.org/wiki/Optical_path_length

    The optical path difference between the paths taken by two identical waves can then be used to find the phase change. Finally, using the phase change, the interference between the two waves can be calculated. Fermat's principle states that the path light takes between two points is the path that has the minimum optical path length.

  7. Centrosymmetry - Wikipedia

    en.wikipedia.org/wiki/Centrosymmetry

    Benzene is a centrosymmetric molecule having a centre of symmetry at the centre. In crystallography, a centrosymmetric point group contains an inversion center as one of its symmetry elements. [1] In such a point group, for every point (x, y, z) in the unit cell there is an indistinguishable point (-x, -y, -z).

  8. Optical spectrometer - Wikipedia

    en.wikipedia.org/wiki/Optical_spectrometer

    Below optical frequencies (that is, at microwave and radio frequencies), the spectrum analyzer is a closely related electronic device. Spectrometers are used in many fields. For example, they are used in astronomy to analyze the radiation from objects and deduce their chemical composition.

  9. Optical glass - Wikipedia

    en.wikipedia.org/wiki/Optical_glass

    Optical glass refers to a quality of glass suitable for the manufacture of optical systems such as optical lenses, prisms or mirrors.Unlike window glass or crystal, whose formula is adapted to the desired aesthetic effect, optical glass contains additives designed to modify certain optical or mechanical properties of the glass: refractive index, dispersion, transmittance, thermal expansion and ...
