Interview with Richard Stephens from Opto

Opto’s body is made from lightweight, closed cell, injection moulded cross linked foam called XL EXTRALIGHT® (http://xlextralight.com/en/). The front cover and other plastic parts are made from injection moulded Copolymer Polypropylene, which is one of the toughest plastics available whilst also being widely recyclable. The lenses are made from PMMA which is lightweight, shatterproof and has excellent light conducting properties.
