Hamamatsu Photonics introduces the new ORCA Flash4.0 LT with W-VIEW Mode™ which enables read out of two different regions of interests (ROIs) with different exposure times.

The ORCA Flash4.0 LT is equipped with the latest Gen II sCMOS technology having a spatial resolution of 2048 x 2048 pixels (6.5µm pixel size) and a very low readout noise of 1.5 electrons rms. The USB 3.0 interface delivers 30 full frames per second.

Operating the camera in the new W-VIEW Mode™ allows you to set independent exposure times and readout directions for the upper and lower half of the sensor (each being 2048 x 1024 pixels) guaranteeing best image quality for simultaneous dual wavelength measurements, especially when used with our dual-view GEMINI.Furthermore it is now possible to read out two freely positioned ROIs of different size and independent exposure times. In this way two ROI images can be acquired at very high speed which reduces data volume and enables long time recording – a crucial feature for light-sheet applications.

The new ORCA Flash4.0 LT in W-VIEW Mode™ allows you to capture simultaneous dual wavelength measurements easily, making it the best choice for high speed ratio metric imaging or any other multi-wavelength fluorescence applications.
