SPIE expects to welcome some 20,000 photonics industry professionals, from company representatives to engineers, researchers and students who will travel from around the world, to the Moscone Center in San Francisco from Feb. 1-6 for the annual Photonics West conference and trade show. The conference will feature a wide range of papers – 4500, plus 17 plenary and hot-topic presentations – on biophotonics, translational research, industrial lasers, optoelectronics, microfabrication, optical MEMS and more. The technical conference will comprise five major topics: • BiOS will feature the latest in biophotonics, including biomedical optics, photonic therapeutics and diagnostics, tissue engineering, translational research, tissue optics, laser-tissue interaction, clinical technologies and systems, biomedical spectroscopy, microscopy, imaging and nanobiophotonics. The Translational Research segment will include photonic developments with high potential to affect health care in the areas of cancer, and heart and neurological diseases.

The event also will include 40 special events, 70 courses, and the BiOS and Photonics West exhibitions. The BiOS Expo will be held Feb. 1-2; in 2013, it sold out, with more than 220 companies. The Photonics West exhibition will run Feb. 4-6; it also sold out in 2013, with more than 1230 companies. SPIE predicts approximately 1300 companies will exhibit in 2014. The annual ceremony for the Prism Awards for Photonics Innovation, co-sponsored with Photonics Media, will be held during the event.
