LASER World of PHOTONICS 2019 exhibition to showcase latest in photonics
Here at Laser Focus World, we reached out to companies to learn ahead of time what photonics products and technologies they will be demonstrating on the exhibit floor.
Held every other year during odd-numbered years, the LASER World of PHOTONICS trade fair and exhibition has a typical draw of 30,000-plus attendees—and 2019 is keeping pace with that trend. This year's show is expected to bring together close to 32,000 photonics researchers and professionals, all of whom will have access to over 1300 exhibitors showcasing their photonics products and technologies.
Here at Laser Focus World, we reached out to companies to learn ahead of time what products and technologies they will be demonstrating on the exhibit floor—here's what they told us:
