The company sells UVi camera intensifiers, add-ons to high-speed cameras that are designed to add low light and extended spectral range and to provide fast gating in a compact, lens-coupled package. It plans to release a high-resolution intensified CCD camera in the fourth quarter. The company will focus on high-speed imaging in the short term and move toward biomedical applications, including drug discovery and environmental monitoring.
