Medical applications and biological research present a challenging set of requirements for measurement systems, including constantly changing subjects, difficult environmental conditions, and stringent controls, particularly for in vivo measurement.
4D systems for ophthalmic applications enable precise measurement of the shape of contact lenses and lens molds, as well as determining the shape of the eye’s tear layer in vivo.
For biological research Dynamic Interferometry® provides a unique tool that enables cell imaging in real time, at video rates, to track cellular motion and changes in cell volume. The method offers sharper cell imaging, faster acquisition and faster analysis time than other methods. Low light levels avoid phototoxicity and do not require contrast agents, enabling researchers to measure the volume, optical thickness and dry cell mass of live cells and to follow motion and processes over time.
