Abstract
Various light collection systems (10, 20, 30), for providing light to be reflected from, or transmitted by, an SLM. Two systems (10, 20) include reflectors (11, 21), which are designed to collect rear-emitted light from a source, as well as lenses (12, 22) having low f-numbers and achromatic transmission, and may include an integrator (14, 23). A third system (30) includes a special reflector (31) coupled directly to an integrator (33).
