Prototype optofluidic switchable optical element
None:
We report the physical realization and validation of a switchable optical element based on a digitized optofluidic platform previously introduced as an approach to switching between two optical powers. There are numerous applications for switching between different optical powers, with presbyopia correction being one of them. The prototype's ultimate intention is for spectacle lens placement in smart and conventional glasses for switching between refractive and diffractive optical states designed to correspond to near and distance foci. In the current prototype development cycle, we looked into remaining deficiencies of the prototype construction to achieve reliable switching between the optical states. We have also investigated the possibility of controlling the switching remotely. The investigation resulted in the introduction of the refractive optical substrate in addition to the diffractive optical substrate, and resulted in a negative outcome on the use of remote control switching in the form of magnetic force. The position and movement of both optical substrates must be more rigorously controlled for fast switching.

Phase Contrast and Differential Interference Contrast Microscopy
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...
