Video: Meadowlark Spatial Light Modulators at Quantum 2.0 2023

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.

CUbit Continues Growing One Year into Strategic Partnership

In February 2022, Meadowlark Optics and three other organizations became the first industry partners of CUbit at the University of Colorado Boulder. Not to be confused with the ancient unit of measurement, this “CUbit” is a play on words relating to “qubit”: a two-level subatomic system showcasing quantum mechanics. The CUbit Quantum Initiative is a

Waveplate Retardance Metrology: The Basics and Beyond

Waveplate Retardance Metrology: The Basics and Beyond INTRODUCTIONWaveplates are important for the control of the state of polarization and for the measurement of polarization of light. They are modifiers of polarization state but not of the degree of polarization. They do this in a manner described by a parameter called retardance. Most commonly the needed
