Pinhole pupilloplasty is a surgical procedure that aims to narrow the pupil to pinhole size to impart greater depth of focus ...

Please provide your email address to receive an email when new articles are posted on . Pinhole pupilloplasty has been documented to improve visual performance in cases with higher-order aberrations.

While confocal microscopy uses a pinhole to reject out-of-focus light to generate the optical section, a multi-photon (or 2-photon) microscope uses a pulsed infrared laser to stimulate fluorescence ...

Neutrons have a set of unique properties that make them better suited than light, electrons, or x-rays for looking at the physics and chemistry going on inside an object. Scientists working out of MIT ...

The Cell Imaging Center houses two types of confocal microscopes: the Olympus FV1000 and the Zeiss LSM700. In confocal microscopy, laser light is focused into a very small spot and is scanned across ...

Confocal laser scanning microscopes (CLSMs) use a laser to generate a digital image of a given sample. Confocal microscopes work in tandem with ‘fluorescent tagging’, which involves the alteration of ...

Matin Durrani visits the National Institute of Standards and Technology in the US to find out how neutrons are being used to create a unique microscope that can see inside objects that other particles ...

On most of the occasions that I write about microscopy, I talk about big table-top devices with fancy lasers attached to one end and fancy geeks attached to the other. Yet, in my excitement over these ...
