| More recently, it often shows up in fairly complex catadioptric systems as a simple, inexpensive substitute for an aspheric mirror. |
|
| The eye's optical system consists primarily of the cornea and the lens, and the corneal surfaces are aspheric. |
|
| Typically, the designer adds more lens elements or applies small perturbations to spherical shapes using aspheric surfaces. |
|
| The system uses a generalized aspheric optic element placed near the aperture stop of an optical instrument to produce these results. |
|
| The aspheric design makes a sharper and brilliant view possible in relation to the spherical colored exchange systems. |
|
| High-quality vision with enhanced aberration correction of anterior aspheric optics. |
|
| In addition, the higher imaging quality provided by the aspheric design allows an improved utilisation of the field of view. |
|
| The lenses are aspheric monthly lenses and they correct low level astigmatism. |
|
| The element can be a separate component, or it can be integrated onto a traditional lens element by the addition of a generalized aspheric surface. |
|
| Eliminating spherical aberration for a single element requires an aspheric surface, which is easy to design but not to manufacture using conventional manufacturing methods. |
|
| Superimposing such a diffractive structure on an aspheric surface yields an achromatic singlet whose spherical and chromatic aberrations are corrected. |
|
| Frequency 55 aspheric is an aspherical monthly lens for daily wear that corrects slight astigmatism without being toric. |
|
| Transparent plastics also have come into use, especially as they can be molded into elements with aspheric surfaces. |
|
| A reduction of distortion is noted when an aspheric lens is used, and the manufacture of such low-power aspheric plastic magnifiers is a major industry. |
|
| Unlike conventional optical grinding, complex aspheric surfaces can be machined easily. |
|
| It features an aspheric back optic zone, front surface toricity and front surface aberration control for optimal visual acuity. |
|
| The Powell lens is one kind of aspheric lens, which can transform laser beam into a straight laser line. |
|
| Volk's patented double aspheric glass design eliminates distortion and improves stereopsis to the periphery of the 880 field of view. |
|
| Volk's patented double aspheric design maintains linear image magnification and image clarity across the entire field of view with minimum distortion. |
|
| There is no chromatic aberration using a reflector, and distortion and spherical aberration are controlled through the introduction of a carefully contoured aspheric magnifying mirror. |
|
|
|
| Current optical design of optical instruments is based on conic or aspheric surfaces of revolution. |
|
| The advanced 10-group, 15-element lens structure also includes three compound aspheric lenses for images that are crisp and clear, even when shooting at a high zooming ratio. |
|
| It has so-called aspheric optics which gives you an improved quality of sight. Details appear more clearly, contrasts become sharper, colours become clearer and you even see better in the dark. |
|
| The innovative aspheric optics are designed to help improve contrast of the retinal image and consistently reduce spherical aberration across a range of lens powers. |
|
| With these aspheric mirrors, the lifetime is up to 10 ms. |
|
| With advanced Lo-Torque? design and aspheric optics, the new lens gives wearers clear, stable vision achieved through its predictable orientation and rotation. |
|
| Avaira sphere lenses deliver great clarity across all powers thanks to unique aspheric opticsthat minimize spherical aberrations inherent in both the lens and eye. |
|
| We know that many surgeons prefer aspheric lenses because they believe that they correct for spherical aberrations and provide better quality of vision. |
|
| Aspheric surfaces tend to create wavefronts that beat against one another, the changes in one negating the effects of another. |
|
| The unique ZEISS Optic Aspheric IOLs enable reduction and control of the spherical aberrations of the eye while showing low sensitivity to decentration and tilt. |
|
| The STAAR Afinity Collamer Aspheric IOL and Elastimide Silicone Aspheric IOL have proven to reduce spherical aberrations and have met all other CMS requirements for approval. |
