When Extreme Ultraviolet mirror systems having several high-order aspheric surfaces are optimized, the configurations often enter into highly unstable regions of the parameter space. Small changes of system parameters lead then to large changes in ray paths, and therefore optimization algorithms crash because certain assumptions upon which they are based become invalid. We describe a technique that keeps the configuration away from the unstable regions. The central component of our technique is a finite-aberration quantity, the so-called quasi-invariant, which has been originally introduced by H. A. Buchdahl. The quasi-invariant is computed for several rays in the system, and its average change per surface is determined for all surfaces. Small values of these average changes indicate stability. The stabilization technique consists of two steps: First, we obtain a stable initial configuration for subsequent optimization by choosing the system parameters such that the quasi-invariant change per surface is minimal. Then, if the average changes per surfaces of the quasi-invariant remain small during optimization, the configuration is kept in the safe region of the parameter space. This technique is applicable for arbitrary rotationally symmetric optical systems. Examples from the design of aspheric mirror systems for EUV lithography will be given.

The multi-configurative microscopic system for inspecting the wire-bonding of reed frame is designed. Object rays is nearly collimated by a objective lens group which is a common lens group of x2 and x6 imaging lens systems and is splitted by two beam-splitters composed of a penta-prism and a refracting prism. And object rays started from the central region and the boundary region(reed frame region) on semiconductor chip(that is, the object) are imaged at the two different imaging planes by x2 and x6 imaging lens groups, respectively. The x6 imaging lens system with a constant object distance and a constant magnification is well designed by general imaging optics system design method. However, since the depth of wire structure on the reed frame has about +/-3 mm, in order to observe by a constant magnification and at a fixed imaging plane without the dependency on the variation of objective distance generated by the depth of wire structure on the reed frame, the imaging lens system is composed of two separated groups, which should be moved along nonlinear locus like mechanically compensated zoom lenses. The nonlinear equations for zoom locus are derived by using the Gaussian bracket. Refraction powers and positions of each groups are numerically determined by solving the equations, and initial design data for each groups is obtained by using Seidel third order aberration theory. The optimization technique is finally utilized to obtain this multi-configurative microscopic system.

The display of 3D images containing all the depth cues required by the human vision system can be achieved using a reconfigurable Computer Generated Hologram (CGH) with high pixel count. A technique which has been developed to produce CGH's with the required number of pixels, and at video refresh rates, is known as Active Tiling((TM)) (AT). At the heart of an AT system is a set of replication optics which produces multiple images of a Spatial Light Modulator (SLM) onto the CGH. The design of two alternative optical systems for generating a 5x5 tiled array of de-magnified images of a single object is discussed. Results are presented from a 4-channel AT system which has recently been built and demonstrated.

Injection molded optics are frequently applied in many high volume applications. Bar code scanners.. CD / DVD systems, CMOS cameras are a few examples. In all of these applications cost effective and fast design cycles are essential. At Philips High Tech Plastics we developed a design system that touches on all different aspects of the system design. Starting with traditional lens design (sequential ray tracing) and tolerancing we transport the initial design into mechanical solid modeling. During mechanical modeling, tolerances, injection molding design rules and integration of mechanical features, reference marks, etc. are incorporated as well. Here the full advantage of injection molding can be utilized. After the opto - mechanical modeling the system is ported back to non - sequential ray tracing for ghost - and stray light analysis. Finally extended tolerancing is performed in order to come to a robust high volume product. If necessary all or several steps in this design process are repeated in order to arrive at the final design. As an additional requirement the metrology possibilities for the design are checked at an early stage. This integral system approach to optical design, including optical modeling (sequential and non-sequential) combined with mechanical solid modeling is presented using some recent examples.

We present a new suggestion for treating skew rays. In the new suggestion. we hypothetically divide a spherical lens. at each point of intersection of the incident rays with the spherical lens. into two effective perpendicular lengthless cylindrical lenses. One of the hypothetical cylindrical lenses is effective in the vertical direction while the other is effective in the horizontal direction. A method is given for calculating the resulted vertical and horizontal angles of refraction. After calculating these angles one can combine. at that point of incidence. the two components into a vector sum to find the resultant refracted ray. The new suggested method is first discussed and demonstrated for one single lens. and then generalized to optical systems of many components. The method's power and effectiveness in lens and optical systems design is demonstrated. A software package is designed and written for the purpose of optical ray tracing. The new method is implemented in this software. The name we gave to this package is "CALOSD". CALOSD is an acronym for Computer Aided Lens and optical Systems design. CALOSD is capable of producing very accurate tabulated data as well as graphical displays of an optical system and rays traced from different points or angles of view: including a top view.

We present three designs and tolerances of wide-field imagers (30x30 arc-minutes or larger) for astronomical surveying. Two infrared cameras (CPAPIR and PANORAMIX II) were designed for the 0.8-2.4 mum band and a third one (WIRCAM) for the visible and near-infrared band extending from 410 nm to 950 nm. The cameras are installed on the telescopes of the Canada-France-Hawaii (Hawaii, USA) and Mont Megantic Observatories (Quebec, Canada). The three cameras are compact, use only spherical refractive components and have an internal pupil accessible for insertion of filtering components. A Lyot stop must be used in the infrared camera for background rejection. For PANORAMIX II, a set of filters is used at the internal pupil. Correction of the large off-axis aberrations generated by the telescopes, wide spectral coverage, material choices, cryogenic temperature and alignment were the main design challenges. Also, tolerancing was particularly critical for the infrared cameras because they are cryogenically cooled, thus forbidding adjustment of internal components. The cameras theoretical performances are presented in terms of point-spread function, encircled energy and distortion.

Structured design method for automotive lamp reflectors

The design of critical automotive lamp reflectors, e.g. headlamps and fog lamps, is dominated by trial-and-error methods and rules-of-thumb, supported by optical ray-tracing tools like ASAP etc. In many cases these reflectors are designed by aiming small sections to construct the required illumination distribution, which is a time-consuming task and in which case it is very difficult to maintain a continuous reflector surface. The design method presented here is a more structured approach in which the total available front surface is divided in a few relatively large sections, each section designated to produce a certain part of the required light distribution. An optimizing algorithm is used to optimize the separate polynomial reflector sections in combination with a specific burner. In the final step, the separate sections are put together to form a more-or-less continuous reflector surface. Some iteration afterwards is still required because the intersection lines of the polynomial surfaces will generally change the original section boundaries. The design of a front fog reflector lamp is used as a carrier to demonstrate the approach. Three reflector sections are used to design a high-efficiency fog lamp. The light distribution has an excellent horizontal cut-off that basically meets the SAE requirements.

The National Ignition Facility (NIF) requested an optical diagnostic for measuring shock velocities, shock breakout times, and shock emission of objects with sizes of I to 10 mm. For the polar port of the target chamber, an 8-inch triplet lens collects light at f/3 inside a 30-foot-diameter vacuum chamber and uses an optical relay to send the image into two interferometers located at a distance of 160 feet. Light propagates through a viSAR (Velocity Interferometry System for Any Reflector) interferometer employing a Mach-Zehnder configuration. After exiting the interferometers the images are recorded, both by streak cameras and CCD gated imagers. Discrete magnification changes are accomplished by swapping out optical elements. Large dove prisms are used to rotate the image to align a selected region of the object with the slits of the streak cameras. Unique mounting structures are required to remotely control the alignment of the optical axis. Finite Element Analysis (FEA) was performed on all mounting structures. The first 8-inch triplet can be no closer than 500 mm from the target chamber center and is protected by a blast window that has to be replaced after every event. The first several lens groups have to be fused silica for radiation resistance. A frequency-doubled Nd:YAG laser, operating at 659.5 nm, is used to illuminate the moving object. The viSAR laser wavelength had to be different than the first, second, and third harmonics of the NIF drive lasers.
