Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Phase Contrast and Differential Interference Contrast Microscopy

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Area of Science:

  • Optical Engineering
  • Metrology
  • Nanotechnology

Background:

  • Scanning white-light interferometry (SWLI) is a key technique for surface profilometry.
  • Traditional SWLI systems often use halogen lamps or LEDs, which can limit performance in certain applications.
  • Developing advanced light sources is crucial for improving SWLI capabilities.

Purpose of the Study:

  • To integrate a supercontinuum light source into a custom-built scanning white-light interferometer.
  • To evaluate the performance of this new light source for metrology applications.
  • To explore the potential of the supercontinuum source for dynamic measurements.

Main Methods:

  • A supercontinuum light source, generated from a Nd:YAG pumped microstructured optical fiber, was integrated into a scanning interferometer.
  • The temporal coherence length of the supercontinuum source was measured to be 1.21±0.10 µm.
  • The interferometer's performance was validated by measuring the step height of a microelectromechanical system (MEMS) component.

Main Results:

  • The supercontinuum light source provided high output intensity (20-35 mW), suitable for low-reflectivity samples.
  • The interferometer accurately measured a MEMS component step height of 7.027±0.020 µm, consistent with traditional light sources.
  • The supercontinuum source can be modulated at frequencies exceeding 10 MHz.

Conclusions:

  • The integration of a supercontinuum light source significantly enhances SWLI performance.
  • The developed system offers high precision and is suitable for measuring challenging samples.
  • The high modulation capability opens avenues for stroboscopic dynamic measurements in microscale applications.
