Tomatoes, juicy, delicious and even more nutritious -- thanks to LED lighting

2010 0902 G020.jpg

In the Netherlands, they have been growing food in greenhouses for a long time. Lighting systems have improved production and extended growing seasons -- now they're pumping up the nutrition too.

Research by Wageningen University (Netherlands) Greenhouse Horticulture in collaboration with Philips has shown that tomatoes can be even more nutritious when grown with LED lighting. The partnership will be continued in a joint facility for research into the application of LED lamps in horticulture (IDC LED), which was to be opened in Bleiswijk (NL) this week.

In the tomato variety that showed the strongest reaction, the tomatoes receiving extra light from the LEDs contained up to twice as much vitamin C as the tomatoes not exposed to the LEDs. The doubling of the vitamin C level was achieved with an extra dose of light similar to a quarter of the natural light intensity on a sunny day.

Wageningen University and Research Greenhouse Horticulture performed its research within the framework of the project Gezond uit de Kas (Health from the Greenhouse), financed by the Dutch Ministry of Economic Affairs.

An International Inspiration: Attending the International Day of Light 2019 Celebration in Trieste

John Dudley and Perla Viera in Trieste Perla Marlene Viera González, an SPIE Early Career Professional Member working at the Universidad Autonoma de Nuevo Leon, represented the SPIE Student and ECP Membership at the International Day of Light 2019 celebration in Trieste, 16 May. She shares with this community her experiences at the International Centre for Theoretical Physics (ICTP) and the impact of taking part in this annual day of recognizing light. The International Day of Light brings together culture and science.  — SPIE John Dudley, Steering Committee Chair of IDL This phrase was part of the message given by John Dudley during the introduction to the International Day of Light 2019 at the International Centre for Theoretical Physics (ICTP) in Trieste, Italy. And it reflects the importance of bringing together the science, technology, culture, and art that involves light in this emblematic celebration. This year, the IDL celebration was about “Illuminating Ed...

Optics Does That? With Dr. Ashleigh Haruda, Zooarchaeologist.

Dr. Ashleigh Haruda is a zooarchaeologist. Dr. Ashleigh Haruda She examines animal bones found at archaeological sites to investigate the relationship between animals and ancient human societies. These bones reveal information about ancient societies including diet, trade, migration, and market forces. For her doctoral research, she studied pastoralists living in the Central Asian steppe in the Late and Final Bronze Age (1500-800 B.C.E.). These were people who did not practice agriculture, but lived off of their animals, including sheep. “Primarily these people are experiencing their world and their landscape through their animals,” said Haruda. “So, if they fail to move their animals in the right way, or they fail to understand how the weather is going to be that year, they could all die because there was no safety net for them.” By measuring the bones of sheep found in the steppe from the Final Bronze Age, she was able to determine that these pastoralists did not migrate exte...

#FacesofPhotonics: Optimax Director of Technology and Strategy, Jessica DeGroote Nelson

PITCH PERFECT: Optics expert Jessica DeGroote Nelson  SPIE Senior Member Jessica DeGroote Nelson works as the director of technology and strategy at Optimax Systems in Ontario, New York. She also teaches as an adjunct assistant professor at The Institute of Optics at the University of Rochester (UR), and is a Conference Chair for SPIE Optifab 2019.  Nelson also teaches  Optical Materials, Fabrication, and Testing for the Optical Engineer  at SPIE conferences. This course is geared toward optical engineers who are hoping to learn the basics about how optics are made, and ways in which to help reduce the cost of the optics they are designing. It is also offered online. "Optical tolerancing and the cost to fabricate an optic can be a point of tension or confusion between optical designers and optical fabricators," Nelson says. "I teach this course to help give optical designers who are new to the field a few tools in their toolbelt as they navigate toler...
