Standard optics produce a c. 3 mm thick, 45 light sheet (c. 200 mm wide at 250 mm).

Interchangeable 22 light sheet optic available (item H41-3). Pulse separation of between 100 µs – 5 s (in steps of 10 µs). Pulse width of between 10 32 ms (in steps of 10 ) Super-sensitive VGA CMOS sensor: 640 * 480, 6.0 pixels (1/3 format); 50% quantum efficiency at 660 nm; 75 – 110 dB dynamic range; 4.8 V/lux·sec sensitivity. Trigger input enables image pair acquisition to be synchronised with external events. Accepts standard CS- or C-mount lenses (12.5mm f/1.4 lens supplied). Camera exposure can be linked to the laser s pulsing, thereby enabling operation in a lit room Data refresh and recording rate up to 16Hz (dependent on the computer speed, the selected acquisition and PIV analysis parameters and the recording taking place) Real-time, or offline, 2-component vector calculation. Single pass or adaptive multi-pass cross-correlation with 8, 12, 16, 24, 32 or 64 pixel window sizes. 0% or 50% window overlap (i.e. maps of up to 19,000 vectors).

Optional vector interpolation and filtering based on Calculation of the following derived scalars: Vector angle and magnitude;

Vorticity and swirl; Time-averaged mean velocity; RMS and turbulence intensity. Where applicable, vector component and statistical sample number are user-defined
