Here is another impressive image from Tony Hallas [http://www.astrophoto.com/ ]. This is NGC 6559, a star forming region located in the constellation of Sagittarius, about 5000 light years away! This photo was taken using Chroma LRGB #astronomy filters. For more details: [ https://ilphotonics.com/inside-the-constellation-sagittarius/ ]

When it comes to #metrology products and their impact on production processes, some stories stand out. Like all war stories, we share them to learn from past experience. Those companies producing hard disks that tried to save money on testing were all out of business in five years. To read more, click the link: [ https://ilphotonics.com/the-cost-of-metrology/ ]

We are honored to be a sponsor of #Oasis8 in December – Israel’s largest International Conference & Exhibition for Optics and Electro-Optics. See you at our booth (#6) soon in #TelAviv, 12-13 December! To register and join us there, click the link [ https://ilphotonics.com/oasis-8-conference-exhibition/ ].

A research team generated nice, clean, few-cycle, 7-fs pulses from the cascaded multipass cells from a #laser. Only dielectric mirrors are used. Overall transmission is over 80% and pulses have over 80% energy in the main peak. For more information: [ https://ilphotonics.com/clean-few-cycle-7-fs-pulses-generated-by-pharos-laser/ ]

Curious about the different ranges of the spectrum of light that can be used in #astronomy and #astrophotography? A short introductory article mentions all ranges of the electromagnetic spectrum used for astronomical observation. This article focuses on the following questions: What astrophysical systems emit this radiation? What physical processes does this radiation trace? How is this radiation observed, and what are some real-world facilities dedicated to probing this wavelength range?

Scientists working on #laser applications have developed a new technique using BiBurst mode, for high-efficiency and high-quality ablation of silicon. The team has demonstrated that the BiBurst mode can ablate silicon at a volume rate 4.5 times faster than the single-pulse mode with better #ablation quality when delivering the same amount of total laser energy used in the process.

The world’s first on-site neutron #imaging system uses a neutron beam to penetrate high density metals to examine internal structures and organic materials in exceptional detail. Neutrons interact with lighter elements to reveal what x-rays can’t see: hydrogen, water, lithium, cadmium, energetic materials.
