Bose-Einstein Condensation in Alkali Vapors

Meadowlark Optics “The Bose-Einstein Condensate” is a groundbreaking achievement in the field of physics, for which Eric A. Cornell, Carl E. Wieman, and Wolfgang Ketterle were awarded the Nobel Prize in Physics in 2001. It marks a significant milestone in our understanding of quantum mechanics and the behavior of matter at extremely low temperatures. Some […]

Geometric-Phase Microscopy for Quantitative Phase Imaging of Isotropic, Birefringent and Space-Variant Polarization Samples

Geometric-phase microscopy (GPM) uses changes in the phase of light passing through biological specimens to yield high-resolution and high-contrast images, instead of relying on the attenuation of light used conventionally. Polarization optics and a spatial light modulator generate spatially variant polarization states of light that interact with the sample, creating a relative phase shift between transmitted and reflected light waves. By analyzing the phase information, GPM can reveal details not visible with other microscopy techniques. GPM is an effective non-invasive tool for live cell and tissue studies, with potential to enhance biological systems knowledge.
