Historically, it has not been possible to measure diffractive optical surfaces and deterministically correct for symmetric and asymmetric errors inherent in the turning process. The large diffractive zones make it difficult to measure the shape. This process utilizes Taylor Hobson’s PGI 3-D with Advanced Aspherics Analysis (AAU) software, along with Taylor Hobson’s CCI (Optical Profiler) and Precitech’s NanoForm 250Ultra with a rotary B axis and a Fast Tool Servo (FTS).

Precitech Inc. and Taylor Hobson will present this work at the American Society of Precision Engineering (ASPE) 26th Annual Meeting in Denver CO. November 13-18 2011.

More information on this Paper will be available on www.Precitech.com/white papers after the Annual Meeting.

Precitech Inc is a US based company in Keene NH, that provides ultra precision single point and multi axis diamond turning machines for both rotationally symmetric and freeform applications in non-ferrous, ferrous and High Performance metals.

On display during the show was their Nanoform 250 ultra precision lathe with B-axis. Demonstrations using the part centering accessory, ultracomp and the new windows interface during the show. We had many favorable responses to the process automation’s during the show.

Please join us at the Defense, Security and Sensing show in Orlando Fl. this April the 25th through the 28th, 2011.
