In an optical member holder and a projection exposure apparatus having the
same, a light beam radiated from a light source may be formed into light
having a desired shape by selecting one of a plurality of optical
elements. An optical element holder may include a support member to
support the plurality of optical elements, a first driving section to
move or rotate the support member to select one of the optical elements,
and a second driving section to rotate the selected optical element to
adjust an arrangement direction thereof. The light formed by the selected
optical element may be directed through a reticle.
