Freeform Optics

Challenging freeform or anamorphic optics are created at CMM Optic for use in imaging applications, head up displays (HUD) and head mounted displays (HMD).

CMM Optic is one of the few optic manufacturers with the experience, machinery and metrology to create freeform optics accurately and with proof of performance. 

Key Capabilities: Our multi-axis diamond-turning machines allow for fully customized optic solutions. Because of our world-class metrology lab and highly experienced multi-axis CAD operators, we manufacture  non-rotational aspheres, amorphic and anamorphic optics for military, imaging and aerospace uses.
