diffraction gratings News
Waveguide Designs Bring Extended Reality into Sight
Jan 2, 2024 — Here is something David Goldman, vice president of marketing for Lumus, never expected to come into the field of view of waveguides: Wine growers using augmented reality (AR) glasses to teach unskilled labor workers exactly where to prune grape...
Advancements in Diffraction Grating Aim to Change the Rules
Jul 25, 2022 — Because they separate light into its spectral components, diffraction gratings lie at the heart of modern spectrometers, hyperspectral imagers, optical coherence tomography systems, and similar instruments. In the future, gratings may improve...
TRUMPF Leads Funding Round for Optical MEMS Microphone Company
DITZINGEN, Germany, May 2, 2022 — SensiBel, an Oslo, Norway-based microphone technology company, closed a €15 million (~$15.8 million) funding round to ramp up production of its optical MEMS microphone technology. TRUMPF Venture GmbH led the funding round, which sensiBel said...
ETH Team Leads Way to More Precise Diffraction Gratings
ZÜRICH, June 29, 2020 — For decades, scientists have tried to improve the design and production of diffraction gratings, one of the oldest and most important technologies for controlling light. An ETH Zürich team, working with colleagues at Utrecht University and...
Measuring Diffraction Grating Efficiency
Jan 4, 2018 — Diffraction gratings are in most optical spectrometers covering visible, IR and UV spectra. Absorption and emission spectrometers, fluorimeters, inductively coupled plasma instruments and high-performance liquid chromatography equipment all use...
Optometrics Adds Production Labs
LITTLETON, Mass., May 27, 2014 — Optometrics Corp. recently added two laboratories to its Ayer facility, expanding the company's production of planar and concave master diffraction gratings for precision optical replication, as well as patterned beamsplitters, transmission gratings...
Hydrogels Form Precise Sensor
WEST LAFAYETTE, Ind., March 1, 2011 — Researchers are developing a new type of biological and chemical sensor that has few moving parts, is low-cost and yet highly sensitive, sturdy and long-lasting. The "diffraction-based" sensors are made of thin stripes of a gelatinous material...
Cell Phones Facilitate Spectrometry
CHAMPAIGN, Ill., Oct. 19, 2010 — University of Illinois chemistry professor Alexander Scheeline wants to see high school students using their cell phones in class. Not for texting or surfing the Web, but as an analytical chemistry instrument: Using a few basic, inexpensive supplies...
Dynasil Completes Debt Refinancing
WEST BERLIN, N.J., July 17, 2010 — Dynasil Corp. of America announced Tuesday that it has completed the refinancing of its debt with Sovereign/Santander Bank. The move increases its line of credit from $1.2 million to $8 million and provides considerable interest and cash flow...
Dynasil Buys Line from POC
WEST BERLIN, N.J., Jan. 22, 2008 -- Photonics company Dynasil Corp. of America announced today that it has acquired the optical filter business of Precision Optics Corp. (POC) Inc. of Gardner, Mass.The product line being acquired includes the intellectual property, customer base and...
A Clear View of Fused Silica Transmission Gratings
Sep 1, 2005 — Diffraction gratings have been manufactured for more than 200 years. Their development was driven initially by the requirements of spectroscopy, where they have been applied since Joseph von Fraunhofer’s work in the early 1800s. For many years,...
Ultrahigh-Performance Ion-Etched Holographic Diffraction Gratings
Jan 1, 2003 — Up until the mid-1960s, mechanically ruled diffraction gratings with approximately 1800-g/mm ruling density were considered to be the state of the art in spectroscopy. By the late ’60s, scientists had developed diffraction gratings by forming...
