PCO pco.panda 26 DS double shutter PIV camera

Click2Contact

The pco.panda 26 DS sCMOS camera from PCO offers double shutter capabilities, a resolution of 5120 x 5120 pixels and 26 MP images with an inter-framing gap of 1 μs making it suitable for double imaging — a prerequisite to perform particle image velocimetry (PIV) measurements. These include non-intrusive laser optical measurement techniques for research, diagnostics into flow analysis, turbulence, aerodynamics, microfluidics, chemical processing plants, spray atomisation, spray dryers, rotary kilns and combustion processes such as gas turbine combustors used for aero and marine applications.

In PIV, light-scattering particles are added to the flow under test. A laser beam is formed into a light sheet, illuminating the scattering particles twice with a short pulse at a time interval Δt. The lower limit for this time interval is defined by the double image inter-framing time of the camera. The scattered light is recorded onto two consecutive frames of a high-resolution digital camera. The shorter the double image inter-framing time, the higher the flow speeds that can be analysed.

Exposure times for the pco.panda 26 DS range from 6 μs to 350 ms and the frame rate is 7.1 fps at 26 MP resolution. The dynamic range is 66 dB and parasitic light sensitivity 1:10,000 so users can achieve a low readout noise and dark current.

The compact housing design of the camera and interface provide easy integration. No external power supply is required and power and fast data transfer are through a single USB 3.1 cable.
