An optical system is disclosed that minimizes drop-off problems associated with the process of imaging a small light source to a line. In one embodiment, a singly-curved primary mirror is used to maintain a substantially constant magnification factor of the optical system. In another embodiment, the small light source projects radiation through a cylindrical optical component that partially collimates the light, prior to the light impinging upon a doubly-curved primary mirror. Additional embodiments are shown that combine the cylindrical lens with a Schmidt plate, include an optional aperture stop, and include an optional spatial light modulator, as well as embodiments which vary the positioning of the elements in the optical system along the optical path.
