Properly Tolerancing Aspheric Lenses to Balance Cost and Performance

Understanding how to effectively tolerance aspheres is an incredibly useful communication tool to get the most out of your lens. In this article, we will provide some context behind asphere tolerances, exploring the factors that influence cost and performance.

Catching Lightning With Phantom Cameras

Astroparticle Physicist Dr. Rasha Abbasi, an Assistant Professor in the Department of Physics at Loyola University Chicago, works with the Telescope Array project. Located west of Delta, Utah, the project is an international collaboration between universities to observe high-energy cosmic rays. Abbasi and her team study how TGFs originate from the Earth’s atmosphere and propagate. In particular, the team hopes to answer key questions.

Better LIDAR in Autonomous Systems Starts with MEMS

The global market for automotive LIDAR is expected to grow from $332 million in 2022 to more than $4.5 billion by 2028. We interviewed Eric Aguilar, co-founder and CEO of Omnitron Sensors, Los Angeles, CA, to learn about a new MEMS scanning mirror that could accelerate the market adoption of LIDAR.

A New Optical Metamaterial Makes True One-Way Glass Possible

A new approach has allowed researchers at Aalto University to design a kind of metamaterial that has so far been beyond the reach of existing technologies. Unlike natural materials, metamaterials and metasurfaces can be tailored to have specific electromagnetic properties, which means scientists can create materials with features desirable for industrial applications.

Advancements Make Laser-Based Imaging Simpler and Three-Dimensional

There are times when scientific progress comes in the form of discovering something completely new. Other times, progress boils down to doing something better, faster, or more easily. New research from the lab of Caltech’s Lihong Wang, the Bren Professor of Medical Engineering and Electrical Engineering, is the latter. Read on to learn more.

Optical Invention Mirrors the Image Processing Power of a Human Eye

Mimicking the easy, instantaneous image processing power of the human eye, Penn State electrical engineering researchers created a metasurface, an optical element akin to a glass slide that uses tiny nanostructures, placed at different angles to control light.

New Products

See the new products, including TRIOPTICS’ ATS alignment turning stations, VIAVI Solutions' expanded fiber optic test solutions portfolio, LumeDEL's fiberoptic collimating lenses, Teledyne FLIR's Neutrino LC OGI optical gas imaging camera module, and IDS' Sony sensor.

Liquid Crystals Hold the Key to Shapeshifting Robots

Robots and cameras of the future could be made of liquid crystals, thanks to a new discovery that significantly expands the potential of the chemicals already common in computer displays and digital watches. The findings are a simple and inexpensive way to manipulate the molecular properties of liquid crystals with light exposure.

Smart Contact Lenses to Diagnose Glaucoma

Usually developing slowly over time, many cases of glaucoma are only picked up during routine eye tests, by which time lasting damage may already have been caused. But this could change in the future as academics from the U.K. and Türkiye have developed a contact lens which can detect changes in eye pressure which signal possible glaucoma.

Light-Based Tech to Navigate the Moon

RMIT University’s Arnan Mitchell and University of Adelaide’s Dr. Andy Boes led an international team to review lithium niobate’s capabilities and potential applications in the journal Science. The team is working to make navigation systems that help rovers drive on the Moon — where GPS is unable to work — later this decade.

Restoring Sight to Euclid's Visible Instrument System

A newly devised procedure to de-ice Euclid's optics has performed significantly better than hoped. Light coming in to the visible ‘VIS’ instrument from distant stars was gradually...
