The QSI RS series features a range of full-frame and interline transfer CCDs from 768x512 pixels up to 8.3MP. Dual-read rates of up to 8 MHz with USB 2.0, deep cooling to greater than 45°C below ambient and 16-bit pixel depth allow QSI RS series cameras to produce images with high frame rates, wide range, linearity and low noise. RS series cameras are available with no-coverglass CCDs and fused silica windows for transmission across a spectrum of light from as low as 240 nm in the ultraviolet through the visual band up to 1,100 nm in the near infrared. RS 4.2 and RS 2.0 models support particle image velocimetry exposure mode for flow visualization with two exposures.
