ABSTRACT:
A projection system comprising an illumination relay, a coupling lens, a modulation device, and a projection lens is provided. The illumination relay is configured to provide an illumination beam to the coupling lens along an illumination path having a first optical axis. The coupling lens is configured to direct the illumination beam onto the modulation device. The modulation device is configured to modulate the illumination beam to form an imaging beam and reflect the imaging beam into the coupling lens. The coupling lens is configured to direct the imaging beam into the projection lens along a projection path having a first optical axis such that the second optical axis is substantially parallel with the first optical axis.
