Actually, after this iterative workflow, systems that are already focusing quite well often benefit the most from optimizing for minimal wavefront error. In this way, you can use reTORT to provide a solid basis for iterative, low-aberration lens design. Supports a superior workflow in optical lens design. Their lens system are likely to be introducing the most wavefront error Your ability to understand which surfaces in Your ability in reTORT to view a table of per-surfaceĪberrations is a powerful tool. Or it may lead you to remove lenses where there is too much glass, reducing size and weight. In this way, you, the optical designer, can add corrective lenses in problem areas. As an example, by using the Seidel aberration result table in reTORT, the optical designer can figure out which lenses are introducing the most aberration. ReTORT can correct all common aberrations as well as higher order terms. You may not even be close to your correct solution. Instead, it may point you to a near optimum. This can make the optimization search space difficult to navigate. We do not recommend you begin by optimizing for minimal wavefront error. reTORT offers the ability to optimize lens systems for any of these goals. You may also target aberrations such as wavefront error or a particular aberration component. You often optimize lens systems by targeting resolution metrics such as spot size or MTF. Our job in providing you with reTORT is to make You will find reTORT gives you the tools to minimize opticalĪberrations effectively and quickly. Instead, due to theseĪberration components, the lens produces a blur circle. Light and ideally focuses it at a single point. You may have heard of seven primary aberrations. The six common optical aberration components are below. We’ll address some of the issues involved in minimizing optical aberrations below. Whether Seidel or Zernike, each of these has its place and its following among optical designers. Whichever suits your purpose, you get the most accurate computations with reTORT v2.0.27. And, reTORT calculates each of these directly. Not only that, you even have your choice of whether to use Seidel or Zernike functions. And you will find the most flexibility in optimization goals. ReTORT ray tracer v2.0.27 offers the most rugged optimization schemes on the market today. Optimization goals, even your priority of goals, can make or break your optical Rugged optimization scheme is one secret to eliminating optical aberrations. They can be simply the shape, curvature, or the placement of a lens in a complex lens system. However, optical aberrations are frequently the result of a non-optimized design. They are not necessarily material or manufacturing defects. Lens aberrations are normally defects in the design of the lens or lens system. Minimizing Optical Aberrations is the end goal of any lens system design. Minimizing Optical Aberrations – Focus on Seidel or Zernike
