title: Quantum counter photodetectors: a new design.
abstract: A new design for quantum counter cells is described that uses total internal reflection to minimize depth-of-penetration and polarization effects. This new cell is compared to a standard 1-cm thick quantum counter cylindrical cell. Solutions of 5 g/liter of rhodamine B chloride in ethylene glycol were used in both cells. The fluorescence emission from the cell was found to be significantly less polarized and also less dependent on excitation wavelength.
