OptiPro is an expert when it comes to optical grinding, polishing, and metrology processes. Our team of engineers, scientists and mathematicians will be presenting four papers on various different topics pertaining to the topics of "Grinding and Polishing Processes" (Sessions 1 and 2), "Aspheric and Meter Class Optics" (Session 3), and "Metrology" (Session 5). If you are unsure of the capabilities of OptiPro's equipment, we invite you to attend these presentations delivered by some of the most knowledgeable and experienced individuals in the field of optical fabrication. See the schedule below for the titles of each paper, the time of each presentation, and the authors of each paper.
Paper TD07-3
Title: OptiPro's fabrication and metrology solutions for aspheres and freeform surfaces
Date and Time: Monday, May 9th, 8:40 AM - 9:00 AM
Authors: David E. Mohring, Edward M. Fess, Michael J. Bechtold, OptiPro Systems
Abstract: OptiPro Systems has developed optical fabrication equipment for the precision optics industry since 1988. Our relationship with the Center for Optics Manufacturing, Universities and industrial partners has led us to design and build cost effective state of the art manufacturing and metrology solutions. The use of CNC grinding machines utilizing deterministic techniques has been enhanced with Hi speed CNC spherical polishers to address spherical dome fabrication requirements. The advent of aspheres has driven the requirement for cost effective non-spherical fabrication. The eSX, UltraForm Finishing (UFF), OptiTrace and UltraSurf platforms provide grinding, polishing and metrology solutions for fast asphere/freeform production.
Paper TD07-10
Title: Increasing the determinism of sub-aperture polishing
Date and Time: Monday, May 9th, 11:30 AM - 11:50 AM
Authors: Scott Bambrick, Michael J. Bechtold, David E. Mohring, Scott DeFisher, OptiPro Systems
Abstract: In recent years the fabrication of aspheres has approached economical prices. Much of that decrease in price is directly related to the availability of sub-aperture polishing systems capable of deterministic figure correction. These machines have enabled operators to fabricate shapes that would have been too costly to manufacture using artisan techniques. However, to get the most out of these machines care must be taken during the set up of these processes. A brief description of common sub-aperture errors will be presented as well as the solutions to those errors.

Title: UltraForm Finishing (UFF) spotting technique for studying polishing process conditions for optical materials
Date and Time: Monday, May 9th, 2:40 PM - 3:00 PM
Authors: Christopher Roll, Paul D. Funkenbusch, Univ. of Rochester; Scott Bambrick, OptiPro Systems
Abstract: We demonstrate the use of UltraForm Finishing (UFF) spotting technique for studying polishing process conditions for a variety of optical materials. The UFF is a sub aperture polishing technique that uses a continuous belt of either bound abrasive material or assisted loose abrasive slurries over a rotating wheel. Design of experiment systematic analyzing approach was used to study the effect of process parameters on surface microroughness and material removal rate as well as UFF belts wear. Process parameters include speeds, compression depth and induced normal load, wheel nominal hardness, and UFF belt and coolant/slurry combination.
Paper TD07-25
Title: Non-contact surface measurement of freeform and conformal optics with UltraSurf
Date and Time: Tuesday, May 10th, 9:00 AM - 9:20 AM
Authors: Scott DeFisher, Michael J. Bechtold, David E. Mohring, OptiPro Systems
Abstract: OptiPro Systems is developing the UltraSurf, a non-contact measuring system using state of the art, precision motion control. UltraSurf has the flexibility to handle common metrology problems such as surface roughness, slope error, and high departure. Current UltraSurf research is the qualification of freeform and conformal optics and using measurement data as feedback for sub-aperture polishers. |
