Photoelectric dyes may be used to send images to the brains of the blind, potentially presenting a simpler alternative to artificial eyes based on image sensors. Blind patients with hereditary diseases such as retinitis pigmentosa have dead photoreceptor cells, but other neurons involved in sight remain alive and can be stimulated artificially. Researchers from Okayama University and Okayama University of Science tested the dye in genetically blind rats and found they were able to follow the direction of movement of a spinning drum painted with vertical black and white stripes. ...Read full articleRelated content from Photonics MediaARTICLESImproving Microscope Resolution with Plasmonic MetasurfacesWhile imaging cells using real-time fluorescence microscopy methods, professor Kaoru Tamada of Kyushu University’s Institute for Materials Chemistry and Engineering and her group found that...BioPhotonics Jan/Feb 2021 IssueMicroresonator Measures and Images Nanoparticles with High Degree of SensitivityScientists at the Okinawa Institute of Science and Technology (OIST) Graduate University have developed a light-based device that can act as a biosensor, detecting biological substances in materials,...BioPhotonics Mar/Apr 2020 Issue3D Printing Provides Building Blocks of Healing in Scaffold DesignA group of researchers has demonstrated that assembling a network of tiny, approximately 1.5-mm3 blocks with the aid of optical technology can be an effective way to accelerate healing in tissue and...BioPhotonics Nov/Dec 2020 IssueScientists Make Vampire Bats Glow to Simulate Vaccine SpreadUniversity of Michigan scientists and their colleagues used glowing fluorescent gel to test the potential effectiveness of vaccines to control rabies and other diseases in wild bats.

Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear. Some precautions still exist, though.When purchasing an industrial laser system, the astute buyer will look for a Class 1 laser product — a system where the laser beam hazard is completely enclosed and there is no potential laser...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookHigh-Brightness LEDs: A Boost from High-Performance Silicones: Ongoing advancements pave the way for high-power LEDs in broader application areas.High-brightness LEDs have found their way into applications such as signs and displays, cell phone flash modules, automotive lighting and general illumination.
