Part by Part: The Anatomy of a Raman Microscope
Feb 1, 2024 — Raman microscopy is a fantastic technique for analyzing the chemical composition of samples. It is a nondestructive technique that mitigates the need for material preparation and the use of stains or dyes. Further, combining Raman spectroscopy with microscopy enables high spatial resolution to be obtained that can be applied to particles measuring a few micrometers in size. This versatility has prompted use of the technology in a wide range of applications and end markets, from semiconductors...
Tunable Metalens Can Change Its Focus in Real Time, Like a Human Eye
CAMBRIDGE, Mass., Feb. 26, 2018 — Researchers have demonstrated electrically tunable large-area metalenses controlled by artificial muscle technology. The adaptive metalens simultaneously controls for three of the major contributors to blurry images: focus, astigmatism and image...
Imaging Startup Closes Seed Funding Round
CHAMPAIGN, Ill., Nov. 7, 2013 — Quantitative imaging startup Phi Optics Inc. has closed its seed funding round with $250,000 from venture capital groups, the company said Wednesday. Phi Optics develops imaging solutions for life sciences and biopharmaceutical researchers and was...
Light Tube Grabs, Scans Tiniest Bacterium
FREIBURG, Germany, Oct. 5, 2012 — A light tube that can grab, orient and record the movements of tiny agile unicellular organisms may soon help scientists better understand bacterial infectious diseases.
Thousands of Cells Tracked Via Lensless Imaging
LOS ANGELES, Sept. 18, 2012 — A novel lensless computational imaging platform is being touted as a new way to observe and track large numbers of rapidly moving objects under a microscope, capturing precise motion paths in three dimensions. For the first time, the 3-D helical...
Nanocrystal Films Promising for Photonic Circuits
CAMBRIDGE, Mass., Aug. 24, 2012 — A new process for patterning defect-free nanocrystal films with nanometer precision could advance photonic devices and basic physics research.
Optical Microscope Exceeds Diffraction Limit
AMSTERDAM, LONDON and BARCELONA, Spain, Aug. 22, 2012 — An optical microscope that combines electronic excitation and optical detection has broken Abbe’s diffraction limit. The nanoscale imaging method offers insight into how light and complex photonic materials interact and could lead to enhanced...
Nanostars Seen as Superior for SERS
HOUSTON, March 29, 2012 — Synthesized starfruit-shaped gold nanorods could strengthen applications that rely on surface-enhanced Raman spectroscopy.
Synchrotron enables faster, better tissue imaging
MILWAUKEE – A synchrotron-based imaging technique delivers intensity a million times brighter than sunlight – and offers high-resolution pictures of the molecular composition of tissues with high speed and quality. A team of researchers from the...
Microscope beats diffraction limit
MANCHESTER, UK – A new microscope has shattered the record for the smallest object the eye can see, beating the diffraction limit of light and promising to promote understanding of the causes of many diseases. Standard optical microscopes can see items clearly at...
Tracking ultrafast laser ablation to tune nanoparticle films
NAPLES, Italy – Ultrafast laser ablation yields two distinctly different plumes, and the behavior of both can be described well by models, researchers report. That information could be used to produce novel nanoparticle films of magnetic and semiconductor...
Olympus America Licenses Patents to BioImagene
CENTER VALLEY, Pa., July 26, 2010 — BioImagene Inc. and Olympus America Inc. have signed a nonexclusive worldwide licensing agreement that allows BioImagene to access Olympus’ patent portfolio in the field of digital pathology and virtual microscopy. The license is the...
Olympus Canada to Distribute Hitachi Tabletop SEM
MARKHAM, Ontario, April 30, 2010 — Hitachi High-Technologies Canada has partnered with Olympus Canada Inc., naming the latter company as the exclusive distributor of its TM3000 tabletop scanning electron microscope (SEM) in Canada. The fully-automated, tabletop SEM can achieve...
Omnyx Licenses Olympus Patents
CENTER VALLEY, Pa., March 15, 2010 – Olympus America Inc. signed a nonexclusive worldwide licensing agreement with Omnyx LLC, a joint venture of GE Healthcare and the University of Pittsburgh Medical Center. The agreement will allow Omnyx to access Olympus America’s extensive...
Putting Imaging in the Picture
Feb 28, 2010 — It is now more than 180 years since the first image was captured by Joseph Nicéphore Niépce from an upstairs window on his estate in France using pewter plates and a camera obscura...
The art of microspectroscopy
Feb 28, 2010 — Martin noted that both spectra and high-resolution digital images can be acquired with the company’s microspectrophotometers, also known as microspectrometers (including its QDI 2010 model), which are designed to measure the UV-VIS-NIR spectra of...
Defect-free Thin Films Realized
ITHICA, NY, Jan. 22, 2010 – To make thin films for semiconductors in electronic devices, layers of atoms must be grown in neat, crystalline sheets. But while some materials grow smooth crystals, others tend t...
Incandescent Nanotube Lamp
LOS ANGELES, Calif., May 7, 2009 – In an effort to explore the boundary between thermodynamics and quantum mechanics – two fundamental, yet seemingly incompatible theories of physics – a team from the UCLA Department of Physics and Astronomy has created the world's smallest...
AFM Images Breathing Bacteria
COLUMBUS, Ohio, March 17, 2009 – A combination of atomic force and optical microscopes revealed that common soil bacteria can “inhale” toxic metals and “exhale” them in a nontoxic form, researchers at Ohio State University said. The process could be used to clean up toxic chemicals.
Ivy’s Secret Is in Its Secretions
May 1, 2008 — As anyone knows who has ever been to Wrigley Field in Chicago, ivy climbs, it covers and it spreads over almost anything in its path. The plant’s famed surface-climbing ability has made it a fixture in country gardens, on urban buildings and in...
Wrinkles Measure Thin Films
AMHERST, Mass., Aug. 6, 2007 -- A simple new experiment yields important information about the mechanical properties of thin films -- nanoscopically thin layers of material that are deposited onto a metal, ceramic or semiconductor base -- and this inexpensive way to measure...
Helium-Ion Microscopy
Aug 1, 2007 — When it comes to imaging at high magnifications, the traditional optical microscope has given way to a number of alternative technologies, each with its advantages and its shortcomings. One, the scanning electron microscope (SEM), has been around...
Hybrid Microscope Combines Optics, Ultrafast Laser
BOULDER, Colo., Oct. 27, 2006 -- A new hybrid device that combines an optical microscope with an ultrafast laser could be used to simultaneously image both the electronic and physical patterns in devices such as nanotransistors or to identify the chemicals or elements that comprise...
Imaging with Electrons, Aided by Light
Sep 1, 2005 — Researchers at California Institute of Technology in Pasadena have developed an instrument with the spatial resolution of an electron microscope and the imaging speed of an optical microscope. They have dubbed it the ultrafast electron...
