A number of preliminary optical designs for a new generation of 4 metre astronomical survey telescopes have been investigated. These have large fields of view and operate in both the visible and near IR astronomical wavebands. Typical requirements for dual band systems of this type are presented. Two designs for prime focus refractive field corrector systems are presented, with and without aspheric surfaces. The use of aspheric surfaces on the field corrector lenses is shown to allow a large field of view (2 degrees diameter) to be achieved. A design for a three mirror reflective system is presented which also allows a 2 degrees field to be achieved. An infrared imager, based on a modified Schmidt camera, is presented which allows a 1 degrees field of view to be achieved. Additionally, a modified Ritchey-Chretien telescope, incorporating refracting field corrector lenses is presented. This design provides a large field of view over both the visible and lR wavebands. The mechanical constraints of combining these systems into dual channel systems are also discussed.

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.

The present research is part of an effort to develop tools that make the lens design process more systematic. In typical optical design tasks, the presence of many local minima in the optical merit function landscape makes design non-trivial. With the method of Saddle Point Construction (SPC) which was developed recently ([F. Bociort and M. van Turnhout, Opt. engineering 48, 063001 (2009)]) new local minima are obtained efficiently from known ones by adding and removing lenses in a systematic way. To illustrate how SPC and special properties of the lens design landscape can be used, we will present the step-by-step design of a wide-angle pinhole lens and the automatic design of a 9-lens system which, after further development with traditional techniques, is capable of good performance. We also give an example that shows how to visualize the saddle point that can be constructed at any surface of any design of an imaging system that is a local minimum.

Achromatic doublet theory is recast for the 1-2.5 mu m short-wavelength infrared band, suggesting the desirability of combining barium fluoride with specific high index optical glasses having large differences in primary SWIR dispersion and small differences in partial SWIR dispersion. Candidate combinations of materials are screened empirically using the performance of optimized f/3 airspaced achromatic doublets employing barium fluoride as the positive element. Polychromatic RMS geometric image spot sizes appear to increase quadratically with difference in partial SWIR dispersion between barium fluoride and the complementary glasses. Examples of complex (fast, wide field) systems demonstrate the utility of the most promising combinations.

The design of high quality very wide-angle optical systems (FFOV > 100 degrees) relies on distortion to obtain a sufficient resolution at, usually, the center of the field of view. Using distortion shape as a parameter during optimization to reach a magnification target is a common technique to achieve optical foveation during the lens design process. This method allows resolution enhancement at selected parts of the field of view since less care is given to parts of the image that are deemed less important. However, accurate control of distortion can be a challenge during optical design since the standard aspherics polynomials don't correlate directly to image magnification. This may in fact slow down optimization since the merit function is much less optimized to approach a solution. In this paper, we address this problem by presenting a method to simplify distortion control during the optical design phase. To achieve this, the use of orthogonal polynomials is used for defining the optical surface shape and will then be used to compare the height of the image plane at a given field of view. We show that in the case of simple and paraxial system, this process is orthogonal and achieve a solution in a single optimization step. We will finally discuss the limits of this method and how it applies to modern lens design problems.

Staring infrared imagers have multiple surfaces within the integrated Dewar assembly which contribute to non-traditional Narcissus artifacts. Static non-uniformity correction is insufficient to remove dynamic Narcissus artifacts caused by moving focus or zoom groups. Dynamic Narcissus artifacts often manifest as rings apparent to the human eye, although they may lie near the noise floor of the imager. Moreover, strong field curvature of the Narcissus can complicate diagnosis using paraxial methods. We compare a simple pupil ghost metric to traditional Narcissus metrics and present an experimental case study illustrating how the metric can be used during optimization to eliminate the effect.

The main characteristic of adaptive lenses is to change their shape, and consequently their focal length, by modifying their physical parameters. On the other hand, Fresnel lenses have such features as large aperture, short focal length, they are slim and reduced in size. These kind of lenses have become very popular due to their applications, such as in compound eyes, optical communication systems, photolithography, imaging systems, etc. Nowadays, several kinds of tunable lenses exist such as those made with dielectric materials, lenses that change their focal length by varying the refractive index of the material, liquid lenses composed by elastic membranes and solid elastic lenses. In this work, we present the design, simulation of the mechanical behavior using Finite Element Method (FEM) and cost analysis of an Adaptive Fresnel Lens made of an elastic material, together with a mechanical mounting system. Our study considered the use of design thinking methodology to obtain the best optical design at minimal cost. Analysis, results and future applications are presented.

A conventional camera can be adapted for underwater use by enclosing it in a sealed waterproof pressure housing with a viewport. The viewport, as an optical interface between water and air needs to consider both the camera and water optical characteristics while also providing a high pressure water seal. Limited hydrospace visibility drives a need for wide angle viewports. Practical optical interfaces between seawater and air vary from simple flat plate windows to complex water contact lenses. This paper first provides a brief overview of the physical and optical properties of the ocean environment along with suitable optical materials. This is followed by a discussion of the characteristics of various afocal underwater viewport types including flat windows, domes and the Ivanoff corrector lens, a derivative of a Galilean wide angle camera adapter. Several new and interesting optical designs derived from the Ivanoff corrector lens are presented including a pair of very compact afocal viewport lenses that are compatible with both in water and in air environments and an afocal underwater hyper-hemispherical fisheye lens.

Zoom lens with variable focal length is well fit for researching objectives far and near. design of zoom lens working at mid-wave infrared wavelength (7.7-10.3 m) and its view field 10 degrees is presented. Determination of the initial configuration of the variable and the compensate groups are discussed according to the mechanism compensate curves. The compensate group is determined with positive power. Its focal length changes during a large scope, which is from 300mm to 100mm. And the corresponding F number variables from 3.75 to 1.25. So the residual aberration needs to be carefully corrected. The optimized zoom lens is composed of four group elements, and its performance reaches diffraction limited at each focal position.

Thermal imaging is an important, though challenging, diagnostic for shockwave experiments. Shock-compressed materials undergo transient temperature changes that cannot be recorded with standard (greater than ins response time) infrared detectors. A farther complication arises when optical elements near the experiment are destroyed. We have designed a thermal-imaging system for studying shock temperatures produced inside a gas gun at Sandia National Laboratories. Inexpensive, diamond-turned, parabolic mirrors relay an image of the shocked target to the exterior of the gas gun chamber through a sapphire vacuum port. The 3000-5000-nm portion of this image is directed to an infrared camera which acquires a snapshot of the target with a minimum exposure time of 150 us. A special mask is inserted at the last intermediate image plane, to provide dynamic thermal background recording during the event. Other wavelength bands of this image are split into high-speed detectors operating at 900-1700 nm and at 1700-3000 nm, for time-resolved pyrometry measurements. This system incorporates 90-degree, off-axis parabolic mirrors, which can collect low f/# light over a broad spectral range, for high-speed imaging. Matched mirror pairs must be used so that aberrations cancel. To eliminate image plane tilt, proper tip-to-tip orientation of the parabolic mirrors is required. If one parabolic mirror is rotated 180 degrees about the optical axis connecting the pair of parabolic mirrors, the resulting image is tilted by 60 degrees. Different focal-length mirrors cannot be used to magnify the image without substantially sacrificing image quality. This paper analyzes performance and aberrations of this imaging diagnostic.
