Figure 9

Experimental (red squares) and calculated (blue lines) performance parameters of a telemicroscope in dependence on the extension tube length: object distance (a), total horizontal field of view (b), horizontal field of view per pixel (c), and lateral resolution (d). (Sensor resolution: \(1600 \times 1200\) pixels; sensor size: 7.04 mm × 5.28 mm; pixel size: 4.4μm\(\times 4.4 \mu \)m; focal length: \(f=50\) mm; f-number: \(N=2.8\))
