Aspheric Mirrors

Precision aspheres are created at CMM Optic for use across the spectrum for commercial, defense & security and semiconductor applications.

When an application calls for the ability to collimate light without spherical aberration, you may need a aspheric surface or mirror. With the ability to be smaller, lighter and thinner, aspheric mirrors are an in-demand and possibly inexpensive solution for many commercial applications.

Key Capabilities: Our multi-axis diamond-turning machines allow for fully customized optic solutions. We use our world-class metrology lab to ensure that we deliver exactly what you ordered, on time. In addition to parabolic mirrors, our SPDT capabilities allow us to manufacture Sinusoidal Waveforms, Extruded Shapes, or Diffractives –  whatever complex form your application requires.

Typical applications can include ion-beam figuring (IBF), magneto-rheological finishing (MRF), CMM metrology, or computer generated holograms (GCH).
