Lens mount

The mechanics of the laser-excitation fiber interface include a lens mount and a fiber mount with the three translation adjustments shown in Figure 12.3, plus yaw and pitch. In some cases, these five fiber adjustments are independent, and the procedure for alignment is often painstaking. However, a... 

An example of an immersion optic designed for a filtered probe is given in Fig. 6. The immersion optic can be interfaced to the process via either direct crimping onto the outer tube or a flange interface. Internal to this is a second tube with a lens mounted on... 

Fig. 1 Unit for shear force measurements attached to the surface force apparatus. The sectioned piezo tube (Morgan Matroc) bends depending on the amplitude and polarity of the applied input voltage 17in. The symmetrical leaf springs transfer this bending into lateral oscillations of the liquid crystal film which is sandwiched between two mica sheets glued to the crossed quartz lenses the upper lens attached to the piezo tube and the lower lens mounted on the cantilever spring. The magnitude of these oscillations is detected as the output voltage Uom of the capacitance probe (Japan ADE). In this configuration our shear force unit is a modification of the one proposed first by Klein et al. [8]...

Intemally the camera is divided into three regions, each at a different temperature. AH of the optics and baffling structure including the filter wheels are coimected to a Uquid nitrogen cooled outer radiation shield. The camera lens mount is connected directly to the outer work surface of the inner Uquid heUum cryogen tank. The detector is housed within the assembly that holds the lens and is moimted on a thermaUy isolated aluminum block whose tern-...
