Since the photographs will form a unique reference set for all sampling sites, it is important to ensure a good result. This means using a good camera. A reflex camera with a zoom lens (e.g. 35-85 mm) and macro facility is recommeded, and an electronic flash. 

An experimental set-up using a lens system for the acceleration/retardation of the electrons in conjunction with an electrostatic analyser is shown in Fig. 4.32. The electron spectrometer is a spherical analyser with a mean radius R0 of 101.6 mm combined with a three-aperture zoom lens at the entrance and the exit. Only the purpose and the characteristic properties of the entrance lens will be... 

Figure 4.32 Schematic drawing of an electron spectrometer with acceleration/retardation of the electrons by a three-aperture zoom lens placed at the entrance and exit of a spherical electron spectrometer. The elements of the entrance lens are given by L, (with entrance cone C), L2, and L3 Di and D2 are x-y deflectors for steering the beam and H is a Herzog diaphragm for the compensation of edge effects (see [Her40]).

The next few figures show some typical samples of the kinds of information that can be derived from the flow data. They range from network wide analyses to examinations of the characteristics of specific subnets and even of specific hosts. The analysis system can be viewed as a powerful zoom lens. It is capable at looking at the overall traffic on a few percent of the internet at its widest angle, or at a single host at its highest magnification. 

Count the colonies using a stereoscopic microscope with a zoom lens. The sizing is made easier if a grid is used to measure the size. This is simply made by photocopying graph paper on to an acetate sheet and placing this below the dish to be counted. As the colonies are of macroscopic size it is possible to count them with the naked eye but if several researchers are collaborating and... 

Micromodel floods were recorded on videotape for later analysis. A television camera with a zoom lens allowed magnification levels from 33x to 333x as measured on the monitor s screen. A Fujinon 35mm lens was used for larger fields of view. Recording was made in time lapse for replay in real time, allowing up to 10 days worth of recording on a two-hour tape. 

Figure 33.7 A diagram of sa ampling volume controlled FCS measurement system. The laser light from an argon ion laser (AIL) is introduced to a beam splitter (BS) through an optical fiber (OF1). The diameter of the laser beam is expanded continuously by a motorized zoom lens (ZL). The laser beam is reflected onto a mirrorin a mirror unit turret (MUT) and focused on sample (S) through an objective lens (OL1).

The transmitted X-rays are converted to visible light with a single crystal YAG scintillator (Fig. 8). The scintillator is imaged with either a microscope objective (5X to 20X) or a zoom lens. The field of view can be adjusted between 3mm and 50mm. The image is projected onto a CCD detector. Two different Princeton Instruments (Roper Scientific, San Diego, CA) CCD detectors are used 1) Pentamax camera Kodak...

This is the familiar modular assembly Fig. 9 which is about Im long and 70mm diameter and it remains virtually unchanged. However, detail changes have been made to the Zoom Lens (todule and a higher performance TV camera capsule has been fitted. 

Together with the particular features noted above, the console contains controls for the camera head lighting (2 x 800W and 2 x 300W) zoom lens controls (focus, iris, and zoom) camera pan and tilt indicators for camera temperature with audible warning of high temperature TV monitor and video switching for interconnection to other camera/vldeo systems and a U-Matic video cassette recorder.
