MIRC-X, the six-telescope beam combination instrument developed by the University of Exeter and the University of Michigan, together with C-RED One, a fast, low-noise, IR camera from First Light Imaging, are enabling new perspectives in IR interferometry for astronomy. The MIRC-X imager is now looking at the sky on the CHARA telescope array, the world's highest-resolution imaging facility in IR light, located at the Mount Wilson Observatory in California. The new instrument combines the light from telescopes spaced up to 330 m apart. These characteristics make the CHARA array and the...Read full articleRelated content from Photonics MediaARTICLESAT - Automation Technology Names Seiler CEOAT - Automation Technology has named Daniel Seiler CEO.

They are used to isolate certain wavelengths or colors. Applications range from detecting the gaseous composition of a distant star to visualizing the chemical activity in a human cell. Ultraviolet (UV) bandpass filters (with effective wavelength ranges below 400 nm) pose unique design and manufacturing challenges related to the absorption of materials at short wavelengths.In their earliest forms, UV bandpass filters that were optimized for wavelengths less than 400 nm, such as the Schott UG or the Hoya U-series, were constructed of absorbing compounds in glass. Such...Photonics HandbookNanopositioning: A Step Ahead: It is almost a cliché among students of creativity that innovation occurs at the intersection of fields. Since nanopositioning is a discipline that has enabled swiftly evolving application arenas as diverse as materials science, genomics, photonics, defense, biophysics, and semiconductors, it’s unsurprising that its pace of innovation is nothing short of blistering in recent years.By its original definition, a nanopositioning device is a mechanism capable of repeatedly delivering motion in increments as small as one nanometer.
