Eye scan shows first sign of Alzheimer’s disease
Scanning the lens of a human eye with infrared laser light can reveal the earliest signs of Alzheimer’s disease in a matter of seconds, according to US start-up Neuroptix.
Lasers meet fluids: an integrated approach
An optical manipulation and analysis platform that can fit onto a fingernail could significantly change the field of microfluidics.
ZnO-based LEDs begin to show full-colour potential
Start-up MOXtronics has recently produced the first coloured ZnO-based LEDs. Although the efficiency of these LEDs is not high, the emitters have the potential to outperform GaN rivals.
In situ method drives up yields and reduces costs
There is a lot more to making an optical filter than meets the eye. Dominik Goessi looks at the role of in situ monitoring in the production process and reviews the technology.
Hybrid diffractive optics offer an elegant solution
Thanks to a set of unique properties, diffractive optical elements have the potential to transform light into almost any desired distribution. Joshika Akhil gives the low-down on the technology.
