Scientific imaging app for cellular structure and more. Openlab is a modular imaging program designed specifically for multi-user scientific imaging. Openlab consists of a core program and an extensive range of modules. The core program is designed for image acquisition, measurement, presentation and publication. Modules are available to control hardware or add additional software capability, for example, time lapse imaging, ratio imaging, deconvolution and 3D imaging. The unique modular design concept provides the scientist with a versatile choice of system combinations ranging from inexpensive acquisition systems to advanced systems for visualising cellular structure and function.
