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 optical system, the design could take advantage of compacting overall volume size.

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 constraints and performance criteria. Lens designers are required to manually predefine parameters of lens design based on their intuition and experience.

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 diffraction-limited at .5000u over a .10 degree diameter curved field, giving a 800 mm diameter image. Both mirrors are very close to being parabolas.

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 diameter of front aperture is extremely small because the aperture stop is the first element of this 2X optical zoom lens.

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, mechanical and...

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 improves multiple quality characteristics of optical design, …

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 anamorphic attachment by Hallock Smith. This is a fairly simple example of a design form used in cinematography.

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 maximum field are...

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 elements inside the lens barrel. Six lens elements are employed in the optical system, where up to four elements are actuated.

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 double Gauss lens for a full frame camera with effective control of image aberrations.
