TECHNOLOGY NEWS
Raman spectroscopy among techniques to detect cocaine in alcohol
In two landmark studies published in the journal Drug Testing and Analysis (DTA), U.K. and Swiss research teams have developed techniques that identify dissolved cocaine in bottles of wine or rum.
Researchers convert entangled photons to telecom wavelengths
Using optically dense, ultracold clouds of rubidium atoms, researchers have improved three key elements needed to create telecom-style quantum information networks.
Growing nanowires horizontally yields nano-LEDs
While refining a novel method they developed for making nanowires, chemists at NIST discovered a new way to create nanowires that produce light similar to that from LEDs.
Grazing-incidence mirror for X-ray satellite to be checked with 'pencil beam'
The International X-Ray Observatory satellite's grazing-incidence mirror will be tested by a monochromatic X-ray pencil beam with a 50 micron diameter and a divergence of less than one arc second.

QCL spectrometers can replace FTIRs
Block Engineering's spectrometers based on widely tunable quantum cascade lasers include LaserScan to analyze surface chemistries from a distance of 6 in. to 2 ft., the LaserScope IR microscope, and LaserTune tunable QCL source for researchers.
Block Engineering; Marlborough, MA
 
Aspheres for VIS-IR offer multispectral performance
New REO aspheric lenses fabricated from CaF2, ZnSe, and ZnS substrates feature surface accuracies of lambda/4 at 633 nm to achieve small focused spot sizes, and multilayer thin-film coatings with a densified structure for multispectral performance.

FOCUS ON: Optical Materials
Tough requirements make for tough coatings
What defines a high-performance optical coating in today's world? The answer can depend on system requirements, environmental issues, the coating of unique substrates, and coatings integral to a product.
Ti:sapphire laser crystals reach 200 mm diameter
The unprecedented increase in peak laser powers in recent years has pushed the boundaries of Ti:sapphire crystal-growth technology. High-quality crystals with 200 mm diameter are going into production.
Metamaterial enables darker-than-black radiation absorption
Non-diffraction-limited hyperbolic metamaterials are not only finding applications as hyperlenses and photonic funnels but can also be used as highly efficient radiation absorbers, sucking light into the medium.
New technologies enable cost-effective wafer-level optics
A combination of diamond-turned hard tools and microlithography, as well as advances in metrology, pave the way for high-volume production of wafer-level stacks of lenses for next-gen cameras.
