ABSTRACT:
A device comprising a set of fine, uniform, translucent fibers mounted on a suitable holder. When used in conjunction with appropriate neutral density optical filters, if necessary, on suitable particle sizing instruments, the device can easily and quickly be used to perform three important functions--namely, to accurately check the instrument calibration or response to particle size, to locate the limits of the optical depth of field in the particle illuminating beam, and to test the ability of the instrument to detect and register all validly sampled, single particle events.
