Total Internal Reflection Fluorescence Microscopy01:05

Total Internal Reflection Fluorescence Microscopy

11.0K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

5.2K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Atomic Absorption Spectroscopy: Radiation and Light Sources01:13

Atomic Absorption Spectroscopy: Radiation and Light Sources

1.1K
Atomic absorption spectroscopy (AAS) relies on the Beer-Lambert law, which requires that the radiation source emits a narrow range of wavelengths to match the absorption characteristics of the analyte atom. The primary criteria for choosing an appropriate radiation source in AAS is to provide a precise and intense emission at specific wavelengths that will allow accurate detection of the analyte.
Two common narrow-range 'line' sources used in AAS are hollow-cathode lamps (HCLs) and...

IR Absorption Frequency: Delocalization

1.3K
Electron delocalization refers to the distribution of electrons across multiple atoms within a molecule rather than being confined to a single atom or bond. This phenomenon is common in systems with conjugated bonds—structures where alternating single and double bonds allow π-electrons to move freely across the network. The movement of electrons stabilizes the molecule and can affect various chemical properties, including vibrational frequencies observed in IR spectroscopy.
In IR...

UV–Vis Spectroscopy of Conjugated Systems

8.2K
Organic compounds with conjugated double bonds show strong absorption features in the UV–visible region of the electromagnetic spectrum attributed to π → π* electronic excitations. Generally, a UV–vis absorption spectrum is recorded as a plot of absorbance vs wavelength. The wavelength of maximum absorbance, which manifests as a peak in the absorption spectrum, is denoted as λmax.
One of the factors influencing λmax is the extent of conjugation in...

    Area of Science:

    • Optics and Photonics
    • Materials Science

    Background:

    • Polarization- and wavelength-sensitive absorbers are vital for technologies like photovoltaics, imaging, and telecommunications.
    • Existing absorbers often struggle with homogeneous electromagnetic waves, limiting their application scope.

    • To develop an absorber specifically selective to the topological structure of light.
    • To demonstrate efficient dissipation of light with polarization singularities while rejecting plane waves.

    Main Methods:

    • Utilizing a conical mirror to convert incident beams into a standing wave based on geometrical Pancharatnam-Berry phase.
    • Integrating a "nanowire" absorber along the cone's axis to interact with the standing wave.

    Main Results:

    • The absorber effectively dissipates light containing polarization singularities.
    • Plane waves are rejected irrespective of their polarization state.
    • Nearly perfect energy dissipation is achieved for singularly-polarized light, independent of wavelength.

    Conclusions:

    • The developed absorber demonstrates selective dissipation of topologically structured light.
    • This technology has significant potential for applications in energy harvesting, optical detection, filtering, and telecommunications.
