Beam quality refers to the overall energy or wavelength of the beam and its penetrating power. A high-quality beam has a short wavelength, high mean energy, and increased maximum energy. The kilovoltage controls the beam quality. The kVp regulates the speed of electrons traveling from the cathode to the anode and determines the penetrating ability of the x-ray beam. When the kVp increases, the resulting x-ray beam is of higher energy and increased penetrating ability (Figure 5).1,3,4,7,9

Aspherical lenses are designed to have a much shorter focal length than is possible with regular spherical lenses. They are also corrected for spherical and coma aberrations. Ideally suited for low f-number and high throughput application, condenser quality aspheres are primarily used in high efficiency illumination systems.
