aspheric การใช้

• A projection lens incorporating aspheric elements to correct for spherical aberration.
• This can be prevented by using elements with convoluted aspheric curves.
• The Mr . Magoo look-- aspheric eliminates that.
• It is true that aspheric lenses are used in cameras and binoculars.
• The problem with aspheric lenses is that they are a broad category.
• Unlike conventional optical grinding, complex aspheric surfaces can be machined easily.
• The reading portion is an aspheric " progressive add ".
• It was reported by Otto Ahlstr鰉 in 1950 that most have aspheric surfaces.
• The aspheric elements were created by the use of a membrane polishing technique.
• This is also true with aspheric design lenses.
• An atoric lens design refers to a lens with more complex aspheric lens design.
• Aspheric lenses are also sometimes used for eyeglasses.
• More aesthetic aspheric lens designs are sometimes fitted.
• Hadley also developed ways to make precision aspheric and aerial refracting telescopes of the day.
• The spherical aberration introduced by the LD elements can be corrected with aspheric lens elements.
• Aspheric or atoric design can reduce errors induced by using a suboptimal flatter base-curve.
• It is compensated by designing a multi-lens system or by using an aspheric lens.
• This leads to strong divergences when it comes to fitting the equation to an aspheric surface.
• Polishing and figuring these highly aspheric and non-rotationally symmetric mirror segments presents a major challenge.
• All optics on the first wheel have an aspheric profile to correct for the Hubble spherical aberration.
