This thesis presents a design of an afocal 7.5X zoom lens with maximum resolution of 0.68μm followed by a reversed ray trace method to show and correct kernel aberrations in zoom lens, …

Zoom lens consists of an afocal zoom system + focussing lens Afocal zoom takes in parallel light and changes diameter Acts as a variable beam expander

proposed algorithm to design automatically complex multi-lens optical systems with variable parameters. The obtained results proved the high image quality of the generated 13-lens …

To view distant objects, the eye is placed at RE. An important design consideration in such instruments is to move RE far enough away from the last surface of the eyepiece for …

Combinations of lenses can produce afocal systems. A ray parallel to the axis produces an image ray that is also parallel to the axis. Common afocal systems are telescopes, binoculars and …

2012年10月1日 · Afocal zoom lenses are state of the art modules for magnification changing in instrument optics, especially in the field of scientific and surgical stereo microscopy. Carl...

Zoom lens design • Zoom lenses are a very common (almost the predominant) design task • Most lenses are designed based on zoom/MC techniques – Not just FL, maybe conjugate …

Zoom Lenses Structure • Zoom lens consists of an afocal zoom system + focussing lens • Afocal zoom takes in parallel light and changes diameter • Acts as a variable beam expander • …

2014年12月1日 · We describe the detailed design of a five-element electrostatic afocal-zoom lens. The simplex optimization is used to optimize lens voltages. The method can be applied to multi …

Formulae and design examples are demonstrated for designing an afocal zoom system that has two discrete zoom positions with stationary and accessible real entrance and exit pupils. The …
