摘要
A lens and reflector unit for optical measurements includes first and second convex surface sections of the lens and reflector unit. Both have their respective central normal lines. A first flat surface section has a normal direction that divides the angle between the central normal lines into equal halves. A third convex surface section has a third central normal line, and the fourth convex surface section has a fourth central normal line. A second flat surface section has a normal direction that divides the angle between the third and fourth central normal lines into to equal halves.
