On this page we make our hard- and software available for non-commercial scientific research.
We developed bird laser safety goggles that were custom fit and built to protect the eyes of animals during PIV experiments. The goggle sockets were 3D printed (ProJetTM HD 3500) from clear acrylic material (VisiJet® Crystal) and painted with carbon black acrylic paint (Golden Fluid Acrylics). The lenses were salvaged from professional laser safety goggles with polycarbonate filter lenses of optical density 6. The lenses were cut to size and friction fit to the goggle sockets. The goggle sockets were wrapped around the bird’s head with three pieces of lightweight, self-stick Vetrap Bandaging Tape. The goggles covered the entire eyes of the bird from any direct or stray laser light and could not be taken off by the bird during the experiments. To prevent the goggles from fogging up, we applied a thin film of shaving cream (Barbasol) onto the surface of the lenses. The total weight of the goggles was 1.68 grams, about 5.8% of the bird’s mass (sockets, 0.44 g; lenses, 0.68 g; vet wrap, 0.14 g; paint, 0.34 g; reflective markers, 0.08 g). See the dowlloadable STL file on this page for 3D CAD models of the laser safety goggle design.
