WebMar 27, 2024 · Stereo microscopes are always used to perform dissections of a specimen or sample, therefore, they can also be called dissecting microscopes. As stereo microscopes use 2 light channels, 1 for each eye, they give the observer a magnified, 3-dimensional view of the specimen or sample. This ability makes them practical to use for dissection. WebThe forward-facing camera has a 3 to 10cm depth of field with a 70 viewing angle, whilst the side camera has a 1 to 2cm depth of field.
