Beam expanders In some cases it may be desirable to measure small particles while maintaining a large working distance. This can be solved using a beam expander. The 55X12 Beam Expander can be mounted on the PDA probe using the 60X117 Conical Adapter, and used with the 50X series standard front lenses. In Figure 7-55, the shaded areas show, for example, that combining a beam expander with a f = 310 mm front lens gives roughly the same numerical aperture as a f = 160 mm front lens, thus corresponding to roughly the same particle diameter range. A B 57X80 55X12 60X117 57X80 Figure 7-55: The 57X80 DualPDA Probe with a 55X12 Beam Expander, A, and in basic configuration, B. The same applies for the 57X40 FiberPDA. Additional 1.5× expansion may be achieved with the 41X200 series beam expanders cascaded with the 55X12 Beam Expander. These expanders have built-in front lenses with focal lengths ranging from 500 mm (41X205) to 2000 mm (41X220). Note Do not cascade two 55X12 Beam Expanders since this limits the effective aperture of the segmented focusing lens and leads to incorrect measurements. 7-74 BSA Flow Software: Reference guide
Aperture plates The particle size range measurable by a PDA can also be changed by alternating between different aperture plates positioned behind the receiving front lens. The different aperture plates for the FiberPDA and the DualPDA are shown in Figure 7-56 and Figure 7-57. The difference between the aperture plate types A, B and C is different effective receiver separations corresponding to a small, medium and large measurable size range. The FiberPDA probe includes one set of the FiberPDA aperture plates. The DualPDA probe includes one set of each the FiberPDA and the DualPDA aperture plates. To use a DualPDA probe in FiberPDA configuration, the FiberPDA mask has to be used. Figure 7-56: Aperture plates for the FiberPDA Probe. A - for small, B - for medium, and C - for large particles. Figure 7-57: Aperture plates for the DualPDA Probe. A - for small, B - for medium, and C - for large particles. The aperture plate is kept in place by a mounting ring and a spring washer, and its orientation is fixed by a small pin. To exchange the aperture plate requires the following steps: BSA Flow Software:Reference guide 7-75
