Pushing Freeform Optical Manufacturing to New Heights (.PDF Download)

Part Geometry

Through the support of US Navy Phase I and Phase II SBIRs, Optimax has significantly advanced its ability to manufacture and measure extreme freeform geometries. The most recent shape was designed with an aerodynamic conformal sensor window in mind. The outer dimensions of the finished part will be 585 x 480 x 195 mm, with 170 mm of concave (CC) sag, and deviation from a best fit sphere of over 400 mm. Placing this part firmly in the category of extreme freeform shapes; a shape that possesses a deviation from a best fit sphere that is on the same order as the size of the part. A rendering of what the finished part will look like is shown in Figure 1.
