Free webinar on non-contact, 3D optical surface profilometry for ophthalmic manufacturing

(Nanowerk News) As part of its ongoing series of live webinars on 3D, non-contact surface profilometry, Veeco Instruments Inc. will be hosting a free online seminar on "Non-Contact, 3D Optical Surface Profilometry for Ophthalmic Manufacturing."
Andrew Masters, PhD, VP of Business Development, will broadcast this live webinar on June 15, 2010, at both 8:30am PST and 5:30pm PST. The one-hour presentation will describe new enabling metrologies in both atomic force microscopy and 3D surface profilometry for R&D, QA/QC, and production environments in the rapidly growing ophthalmology industry.

Schematic depicting the creation of liposome-hydrogel hybrids. A solution containing phospholipid ("liposome precursor") mixes with a solution containing hydrogel precursor (a). Blending together at the interface of the two channels, the phospholipid forms liposomes (b) that trap the hydrogel precursor inside. Material outside the vesicles is removed (c) and the liposomes are UV irradiated. This polymerizes the protein chains in the hydrogel and yields a liposome-hydrogel hybrid (d).
Due to an ever increasing demand from an aging population, the ophthalmic contact lens and intraocular lens (IOL) markets have become a very competitive landscape. In such a dynamic environment, rapid material innovation and product development are a key ingredient for success. The requirements placed upon nanometer- to micrometer-scale metrology have been forcing manufacturers to look past the limits of traditional 2D stylus techniques and potentially dated atomic force microscope (AFM) scan modes. Today's surface analysis instruments need to be both highly functional and easy to use so as to enable manufacturers to streamline production, increase yield, and eliminate waste and scrap.
A 15-minute Q&A session will follow the presentation, where webinar attendees can ask the presenter follow-up questions.
Space is limited, so please register today (an internet and computer speakers, or a phone connection will be necessary). To sign up for this webinar, as well as other Veeco webinars on surface profilometry, go to
Webinar will be presented twice on June 15, 2010, at 8:30am PST and 5:30pm PST. Be sure to sign up if interested, even if you may not be able to attend the live session. After the live seminars have been completed, all registrants will be sent a link to a recorded webinar session.
