2010年4月1日 · In this research, a newly developed U-type 2X zoom optical lens design for Digital Light Processing (DLP) projector was proposed. With two prisms assembled in a non-coaxial …

2024年7月4日 · Optical lens design is the starting point when developing an optical imaging system. It is the process of selecting and optimising a set of optical surfaces to meet desired …

Recently I have discovered an amazing design, of just two conic surfaces with three reflections between them. With a 100 meter diameter f/.75 primary mirror and a f/4.6 system it is …

In this paper, a newly design is proposed that its overall total length is reasonably small compared to current mobile phone camera with two million CMOS pixels. The most important is that its …

2015年9月23日 · This paper will outline a systematic process for projection zoom lenses design. A solid specification of the design task in terms of magnification range, image quality therein, …

2010年3月1日 · By comparing the optimal condition (free-form) design set with the initial condition (non free-form), decrease of 43.93% in spherical aberration and 29.89% in coma significantly …

Combinations of lenses with different curvatures about x and y (often just cylindrical surfaces) can be used to magnify an image along the x- or y-axis, as is shown in this classic 2x afocal …

2010年4月1日 · When a U-type 2X zoom optical lens design for Digital Light Processing (DLP) projector was designed by CODE V, we found that the MTF and RI values at position 1 of the …

The optical design of a compact 2 × zoom lens in a lens barrel for miniature cameras is reported. The magnification in the optical system is achieved by means of changing positions of lens …

This is a work-in-progress web application for designing optical lenses consisting of sequential lens elements. It is intended to support practical design of, for example, a large aperture …
