The LV200 has been carefully designed for long-duration cell bioluminescence microscopy and is compatible with a broad range of cameras and objectives. A completely new optical design dramatically increases sensitivity and enables the detailed study of photosensitive cells and luminescence probes at high magnification. An inbuilt system for temperature control, humidity and gas flow helps to keep the cultured cells or tissue slices in a healthy condition throughout the observation period and the unique light-tight enclosure shields the sample and optics from any external light.
