The paraxial magnification of Lens1 can be scanned from × 0.1 to × 10. Piezoelectric actuators (Thorlabs NanoMax320) are provided for fine adjustment with 20 nm resolution. DMD (Discovery 4100) provides 8bpp and a resolution of 1920 × 1080; DMD mirror element is 7.6 ×...
A heliostat is characterized by the type of mounting, i.e., the orientation of the at least two orthogonal axes which are required to properly position the mirror to direct solar energy to the stationary receiver. The heliostat mirror element is attached so it may be rotated about one direct...
Two rays are shown: one coming from and going to the base of each arrow (marginal ray) and the other coming from and going to the tip of each arrow (chief ray). These two rays have general significance in determining the system performance. Figure 1.3: The basic parameters for a ...
5,959,781 discloses a technique that an observer is capable of viewing an image on the display surface of an image display means by using a totally reflecting surface and a beam splitter surface to introduce light into a concave mirror so that a magnified virtual image is displayed. [0006]...

the negative lens group GR has a positive lens disposed closest to the object side and a biconcave lens disposed on the image side of the positive lens; and where a focal length of the positive lens group GF is represented by fF, and an effective aperture of a lens surface of the negat...
a convex lens being interposed between the concave lens and the liquid crystal panel for converting light emanating from the concave lens to parallel rays. 4. A light source device as defined in claim 3 wherein the concave lens has at least one surface formed by a multi-focus curved surface...
(2) the use of separated negative and positive surface powers so that paraxial rays strike the surfaces with negative powers at lower heights than the heights at which they strike surfaces with positive powers, e.g., the use of a separated field flattener having a negative power; and ...
Another type of catadioptric objective for microlithographic reduction projection has only one concave mirror and a folding mirror, as is described at U.S. Pat. No. 5,052,763 and European patent application no. EP 0 869 383 A, which are each hereby incorporated by reference. It is ...
