Glassboro Students Experiment with Optical Engineering


Edmund Optics brought hands-on optical engineering experiments to Glassboro students in Dorothy L. Bullock and Glassboro Intermediate Schools in February. Students learned that optical components are used in medical lasers, drones, space exploration, manufacturing, product testing, self-driving automobiles, augmented reality, defense, security and more.


Edmund Optics engineers Dale Josephson and Michael Brunsman and educational outreach manager Becca Emerich set-up several stations for students. At one station, students used a laser and multiple prisms to redirect light. At another, students learned about fiber optics as they used a laser to send messages through fiber. At a third station, they used a polarizer to detected stress points (flaws) in plastic products.


Seventh- and eighth-grade students in teacher Shannon Batten’s Into to STEM Class had the time for an additional experiment. Emerich gave them 3¢ ball lenses, tape and small, 3D-printed pieces that enabled them to turn their cell phone cameras into microscopes. The students were permitted to take these simple microscopes home with them. Emerich pointed out that such low cost technology could be useful to analyze water or blood in remote, impoverished areas of the world.


Glassboro School District challenges students to “think like scientists” from a young age. Activities like these provide them with plenty of opportunities to do so.

Principal Engineer Dale Josephson works on cell phone microscopes with students Isabella Profico, Reice Griffin, and Katryn Keating. Such microscopes are made with a ball lens, a small, 3D-printed piece and a cell phone.

Polarizers, like the circular one shown here, filter out certain types of light. Scientists can use polarizers to detect stress points (flaws) in plastics.
