| The contribution of Optimax to NASA research continues with the Messenger spacecraft. Optimax has manufactured flight camera lenses for this mission. Messenger will become the first spacecraft to orbit Mercury, and will follow a path through the inner solar system, including two flybys of Venus and three flybys of Mercury. This expedition will deliver the first new spacecraft data from Mercury since Mariner 10 over 30 years ago. The Messenger will follow the timeline below. |

August 2004 – Launch
October 2006 and June 2007 – Flybys of Venus:
January 2008, October 2008 and September 2009 – Flybys of Mercury
Messenger is returning fantastic images. For more information and great photos, follow this link:

Optimax Employee Profile:
Jessica DeGroote
| Jessica DeGroote joined the Optimax team July 2007 as a scientist in the research and development department. Jessica grew up down the road in Williamson NY. She attended the Institute of Optics at the University of Rochester obtaining her B.S., M.S. and Ph.D. under the supervision of Dr. Stephen Jacobs. Jessica has been involved with optics manufacturing throughout most of her college career first an intern at the Center for Optics Manufacturing and then for her thesis work. The title of her thesis is “Surface interactions between nanodiamonds and glass in magnetorheological finishing (MRF)”. Her research included developing a quantitative model characterizing material removal with MRF as a function of various mechanical and chemical glass and MR fluid properties. |

| Since joining Optimax, Jessica has broadened her research topics to include various novel CNC and traditional grinding and polishing methods. She has also organized Optimax collaborations with local Universities, vendors, customers and experts in the field on projects such as evaluating the manufacturability of optical materials new to the market and determining optimum manufacturing and measurement conditions to ensure the highest quality optics for specific applications. One of her most recent projects discovered how to increase the grinding efficiency by a factor of two for the hard polycrystalline IR material aluminum oxynitride (AlON) through altering the surface tension of the carrier fluid. Jessica is also embarking on a long project to study the effects of slurry chemistry, particle and surface charges and how they effect polishing rates and surface roughness values. Outside of Optimax Jessica is busy planning her wedding. Jessica will be marrying her best friend Phil Nelson this November. When Jessica and Phil are not picking out reception halls and wedding favors you will probably find them out looking for houses or on a golf course. Jessica’s presence at Optimax exemplifies our commitment to small volume, high quality and quick delivery through a scientific approach to continuous improvement and manufacturing optics faster, cheaper and to higher precision than yesterday. If you think you have a potential collaboration project, please feel free to contact Jessica, she would love to hear from you! |

July, Optics and Photonics News will publish an article written by Optimax which presents our research on the improvement of optical manufacturing techniques by studying the impact of chemistry on polishing. It is widely accepted that optical polishing is a mechanical process, where removal rate is dependent upon the proportional relationship between pressure and velocity. Our article builds upon current knowledge by contributing information on the chemical aspect of polishing. Specifically, we aim to increase polishing efficiency and reduce the surface roughness of optical components by varying slurry pH. The results of this study will assist manufacturers in the correct choice of slurry pH for their particular application, and will further serve to improve both prediction models and manufacturing processes. |

Don’t miss it – the article will be published in OPN’s July edition.
