(a) Image quality and field of view with the different Infinitube fixed zoom lens tubes in use. The FM50 lens tube gives a field of view of 2 mm × 1.5 mm with a spatial resolution of 2 µm. (b) The reduced field of view achieved when using a FM100 lens tube represents an area of 2 mm × 0.7 mm, with a spatial resolution of 1.2 µm. (c) Further reducing the field of view with a FM200 gives an area of 0.45 mm × 0.32 mm, with a spatial resolution of 1.0 µm. The fiducial based on a # symbol is clearly observed in all figures and allows unambiguous and accurate points of reference to be established to sub-micrometer accuracy. |
