A custom optical stimulator was designed to expose Drosophila to defined intensities and duration of blue light, which induces retinal degeneration in flies. The stimulator was tested by exposing Drosophila melanogaster (w1118) to blue or red light at 6 days post-eclosion and assessing retinal degeneration by immunostaining retinas for the rhabdomere markers phalloidin and Rh1. These original confocal microscopy images were used to generate Figure 18 in Chen et al. (2017, HardwareX), and full details are provided in this study.
