IRO Intensified Relay Optics
upgrades cameras to „high speed gating“, UV-sensitive, intensified imaging systems
IRO is an intensified gated Relay Optics System equipped with an extremely fast high precision shutter control. Digital setting allows variable exposure times down to 10 ns. All settings (gain, delay and width of exposure) can be controlled by LaVision’s DaVis software. IRO can be mounted before almost every imaging system, e.g. „slow-scan“, video and photo cameras. Your camera becomes a „high speed gating“, light intensified imaging system.
Thus IRO is an ideal solution for taking rapid events and low light level imaging, like discharges, fluorescence phenomena or explosions.
Two versions with different optical couplings are available, depending on the size of the CCD camera chip.
Applications
fast events
low light level imaging
discharges
fluorescence phenomena
explosions
Features
