Figure 7-43: The three standard aperture plates for the 57X40 and 57X50 FiberPDA receiving optics. Segmented lens The segmented lens consists of three elements for the FiberPDA reciving probe and four elements for the DualPDA receiving probe. Each segment of this lens focuses a portion of the scattered light on the corresponding multimode fibre. Each segment of this lens has a focal length of 125 mm. The 58N71 FiberPDA detector unit and the 58N81 DualPDA Detector Unit The 58N70 FiberPDA detector unit comprises three photo-multipliers and the 58N81 DualPDA Detector Unit comprises four photo-multipliers. Both of them compise components for calibration and for optical filtering. The multi-mode optical fibres from each probe are connected to this detector unit. The end of the optical fibre cable away from the FiberPDA Probe is split into three branches with one fibre in each, corresponding to U1, U2, U3. The end of the optical fibre cable away from the DualPDA Probe is split into four branches with one fibre in each, corresponding to U1, U2, V1 and V2. Each connects to a receptacle on the back panel of the Detector Unit and directs its light output onto a photo-multiplier tube. Interference Interference filters are mounted in front of each photo-multiplier. filters Figure 7-44: The three standard aperture plates for the 57X80 and 57X90 DualPDA Probe. • FiberPDA 7-48 BSA Flow Software: Reference guide
This is often not necessary in 1D applications, but for 2D and 3D it is indispensable. For 1D applications these filters block out background light and are recommended. With He-Ne lasers use filters for wavelength 623.8 nm (red). With argon lasers use filters for wavelengths 514.5 nm (green), or 488 nm (blue) or 476.5 nm (violet). For 2D applications, the 58N71 2D extension kit is installed in the detector unit. The kit comprises a colour beam splitter, three 514.5 nm interference filters, one 488 nm interference filter and a photo-multiplier. For 3D applications, the 58N72 2D to 3D extension kit is installed. This kit comprises a colour beam splitter, a 476.5 nm interference filter and a photomultiplier. If used for 2D or 3D measurement, i.e. with a 58N71 2D extension kit or (also) a 58N72 3D extension kit installed, the 57X32 filter is required to let in the green light (wavelength 514.5 nm), while blocking out the light carrying the other velocity components. The light from the middle segment of the probe, U3, passes through one (or two) beam splitters separating out the 488 nm (blue) light, which is directed to the photo-multiplier tube for the V channel (2D and 3D), and the 476.5 nm (violet) light, which is received by the photo-multiplier tube for the W channel (3D). • DualPDA For U1 and U2 these have a narrow pass band at 514.5 nm wavelength corresponding to the green argon line. For V1 and V2 the interference filters pass blue light of wavelength 488 nm. The 58N82 DualPDA Velocity Extension Kit comprises a fifth interference filter, with a pass band for the 476.5 nm wavelength. Calibration The electrical response of a photo-multiplier tube lags slightly relative system to the light input. This lag depends partly on the individual tube and partly on the high voltage applied to the photo-multiplier anode. Lack of knowledge of the exact value of the difference in delay between channels U1, U2, V1 and V2 could lead to substantial errors in the estimated phase differences and hence to unreliable calculations of the particle diameter.
