Total Internal Reflection Fluorescence Microscopy01:05

Total Internal Reflection Fluorescence Microscopy

7.2K
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.

IR Spectrometers

1.5K
There are two main infrared (IR) spectrophotometers: dispersive IR spectrometers and Fourier transform infrared (FTIR) spectrometers. In a dispersive IR spectrometer, a beam of infrared radiation produced by a hot wire is divided into two parallel equal-intensity beams using mirrors. One beam passes through the sample, while another is a reference beam. The beams then move through the monochromator, which separates the radiations into a continuous spectrum of different frequencies. The...

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview01:13

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview

608
Attenuated total reflectance (ATR) infrared spectroscopy is a powerful analytical technique used to study the composition of materials. It is widely employed in chemistry, materials science, forensic science, and other fields where sample characterization is required. ATR has several advantages over traditional transmission IR spectroscopy, including the requirement of little to no sample preparation and the ability to analyze a wide range of samples.
The ATR process begins by directing a beam...

    • Photonics and Optical Sensing
    • Materials Science
    • Fiber Optic Sensors

    Background:

    • Accurate refractive index (RI) measurement is crucial in various scientific fields.
    • Temperature fluctuations can significantly impact RI sensor accuracy.
    • Existing sensors often require separate temperature compensation mechanisms.

    Purpose of the Study:

    • To develop an integrated optical fiber sensor for simultaneous refractive index and temperature measurement.
    • To implement a novel thermo-refractometer system with built-in temperature compensation.
    • To enhance the accuracy of refractive index measurements by mitigating temperature-induced errors.

    Main Methods:

    • Fabrication of a lossy mode resonance (LMR)-based refractometer by depositing a titanium dioxide (TiO2) thin film on a D-shaped single-mode fiber.

  • Integration of a fiber Bragg grating (FBG) within the D-shaped region for temperature sensing.
  • Simultaneous monitoring of LMR wavelength shifts (transmission) and FBG spectral displacement (reflection).

    • Main Results:

    • The LMR sensor demonstrated high sensitivity to the surrounding refractive index (SRI) (3725.2 nm/RIU) and temperature (-0.186 nm/°C).
    • The FBG exhibited a temperature sensitivity of 32.6 pm/°C within the 25°C - 45°C range.
    • The combined system effectively compensated for temperature effects, enabling accurate SRI recovery.

    Conclusions:

    • The developed optical fiber thermo-refractometer successfully integrates RI and temperature sensing capabilities.
    • The sensor architecture provides accurate SRI measurements by effectively suppressing temperature cross-sensitivity.
    • This integrated approach offers a robust solution for precise optical sensing applications.
