1. A prismatic reflector for incorporation into a centrifugal separation chamber, comprising:
inner and outer walls; and
first and second end walls, with the first end wall being angled approximately 45° with respect to the second end wall, wherein
the prismatic reflector is formed of a light-transmissive material,
the inner wall is configured to be associated to a curved surface of the centrifugal separation chamber, with the inner wall having a curvature corresponding to a curvature of said curved surface of the centrifugal separation chamber,
the inner wall is configured to receive light traveling along an initial path and transmit the light to the first end wall,
the first end wall is configured to receive the light transmitted through the inner wall and direct the light toward the second end wall in a direction that is angled with respect to the initial path, and
the second end wall is configured to receive the light from the first end wall and transmit the light out of the prismatic reflector.
