Precision Asphere experience coupled with capabilities

Precision aspheres have been a distinguishing product  in the Jupiter facility since the founding of Coastal Optical in 1991.  In 2002, the company transitioned from conventional polishing by master opticians to deterministic CNC polishing using QED’s MRF® technology.
In 2002 JENOPTIK successfully delivered the first MRF® polished aspheric flight hardware to Ball Aerospace for the Calipso program.  Since then, we have regularly delivered precision aspheres in fused silica, calcium fluoride, zerodur, ULE, silicon and optical glasses in sizes from 15 mm to 240 mm in diameter.  Applications include optics for space, military, scientific and entertainment.

The challenges associated with asphere metrology became the key schedule and cost driver after moving to deterministic polishing in 2002.  Time required and costs associated with designing and fabricating null tests frequently were a deciding factor when evaluating use of an asphere.

In 2007, Coastal became an early adopter of  QED’s SSI-A® stitching interferometric technology to reduce the leadtime and unpredictability associated with asphere metrology.

Coastal’s asphere department is now equipped with a full complement of dedicated manufacturing and metrology equipment.
