Abstract
Radiation emitted by a radiation source along a projected path can be diverted by a divergence angle by a lens in the projected path with a first surface and a second surface spaced apart along the projected path with the second surface farther from the radiation source than the first surface. The first surface can be curved and have a normal point perpendicular to a line parallel to the projected path and offset from the projected path by an eccentricity. Radiation striking the first surface can be diverted by a first angle relative to the projected path and can continue to strike the second surface, which diverts the radiation by a second angle. The sum of the first and second angles is the divergence angle. The apparatus can be used in a probe assembly to determine tip clearance of a turbine blade during operation of a gas turbine engine.
