OPTICAL ARRANGEMENT FOR DIGITAL MICROMIRROR DEVICE

摘要

There is provided an optical arrangement comprising a digital micromirror device having a plurality of individually adjustable mirrors, a mirror pair formed from a convex minor and a concave minor having a common centre of curvature, the concave mirror having a greater radius than the convex mirror, characterised in that a collimated space is immediately adjacent the convex minor, and the concave mirror is offset from the convex mirror so as to be capable of forming an image at an effective focal length of the mirror pair. The convex minor and the concave mirror have radii substantially in the proportion 2.5:1, the concave mirror having the greater radius. A confocal microscope using such an arrangement is also provided.
