Asphere Lenses f g

Due to the more complex surface profile of asphere which significantly reduces or eliminate optical aberrations as compared to the simple lens, Aspheric lenses have at least one surface that is not a true sphere,It has been more widely exploited in the lens optical design stage.

Using aspheres to replace a much more complex multi-element spherical system leads to the result of the optical device can be more compact, lighter, transmit more light and in certain cases be cost effective than the multi-lens spherical design.

At Hyperion Optics, we are equipped with Optotech asphere machine which offers our customers with contour deterministic micro grinding (CDMG) service, uses the accuracy and repeatability of a computer numerically controlled machine to grind the optical shape. We start by grinding the best-fit sphere to remove the bulk material and contour the aspheric shape into the optical material from edge to center. Typical materials available of our fabrication capability are optical glass, ZnSe, ZnS, BaF2, GaAs, and chalcogenide glass. We also accept materials supplied by customers.
