Figure 1
Live view of non-fluorescent specimens using the glowscope frame. (a) Illustration shows the light path for transmitted light viewing. Components shown include the smartphone, clip-on lens (black), glowscope frame (gray), stage and viewing platform (transparent), petri dish containing a specimen, and a LED work lamp positioned under the stage and viewing platform. (b) Image view using a smartphone camera without the clip-on lens shows zebrafish embryos (blue arrow, 3 dpf). A standard pencil (eraser side) is shown as a size reference. (c) Image view using the additional clip-on lens shows the same zebrafish embryos and pencil eraser seen in panel (b). Images shown in panels (b–c) are native magnification (not stretched) as seen on live-view, acquired using an Apple iPhone 12 Pro with 1x (middle magnification) lens, 6 × digital zoom.
