Alignment and Testing for a Freeform TelescopeCurrently there is a strong desire to make Earth science less expensive. Freeform optics make these missions less expensive because they allow an optical designer to use fewer mirrors to create roughly the same effect. The main issue with using freeforms is how closely the substrate can be milled to its prescription. Over this summer, our team looked at two freeforms made by Corning Inc. using a brand new process to determine how close these optics are to their set prescriptions and how well NASA could align them.
