The Oosight(R) product line of microscopes, developed at the MBL  and commercialized by Cambridge Research & Instrumentation, Inc. (CRi), has been acquired by Hamilton Thorne, Ltd., a provider of precision laser devices and image analysis systems for the fertility, stem cell, and developmental biology research markets.

Widely used in fertility clinics to assess the health of unfertilized eggs (oocytes), the Oosight system provides live, high-contrast images and captures quantitative data on important oocyte structures using a patented, non-invasive, polarized-light technique. The technology was developed at the MBL by Rudolf Oldenbourg, Michael Shribak and colleagues in the 1990s and 2000s and commercialized by CRi as LC-PolScope(TM) technology. The Oosight system’s visualization capabilities have enabled breakthroughs in assisted reproductive technology, stem cell generation, and developmental biology research.

“The Oosight system is a unique instrument that is complementary to our laser products in both fertility and developmental biology research labs,” remarked David Wolf, President and CEO of Hamilton Thorne. “As a long-term distributor of the Oosight system we have already completed the technical integration of the Oosight with our laser products. We believe that by leveraging our established, world-wide sales channels and investing in product marketing, we can generate incremental sales of the Oosight product.”
