Asphere Lenses

The complex surface profile of an asphere can significantly reduce or even eliminate spherical aberrations comparing to spherical lenses. Hence, asphericals have been increasingly more widely explored and adopted during the optical design stage.

Aspheres can replace a complex multi-element spherical system to achieve a lighter and more compact optical system. The resulting design has higher transmittance and in most cases, costs less than the aspheric optical lensspherical design, especially at production volumes.

Hyperion Optics is equipped with the Optotech aspheric CNC machine that offers Contour Deterministic Micro Grinding (CDMG) service – the machine grinds the optical material to achieve ultra-high precision shape by leveraging the accuracy and repeatability of a computerized, numerically-controlled machine mechanism. Our process begins by grinding the bulk raw material into the closest fitting sphere, and then contouring the aspheric shape from edge to center. Typical available materials within our fabrication capabilities are optical glass, ZnSe, ZnS, BaF2, GaAs, and chalcogenide glass types. We also accept materials supplied by our clients

Optical Machining Centers capability:

Capacities from 5mm to 400mm

1,000 to 24,000 rpm tool spindle

Automatic curve correction

Tool & Workpiece probing system

Dual tool spindles option

Hyperion’s manufacturing procedure eliminates the need for additional investment on tooling and processing fixtures for spherical substrates and preparation, thereby giving customers a quick start to the production schedule. While the aspheric part is being grounded, the profilometer will conduct and transfer measured data to the polisher. In our polishing process, our experienced operators can control the aspheric form error within 1 micron (depending on the diameter of the parts).

MOQ starts at two pieces to ensure optical performance approval. Our fast asphere prototyping has become one of our most popular services for Low Ratio Initial Production (LRIP) projects. We can process both spherical and aspherical parts simultaneously for custom objective and/or eyepiece designs, thereby securing a reliable timeline management to meet the tight timing requirement. In addition, we offer competitive pricing for aspheric coating within our prototyping packages.
