X IDE is a software program used to develop applications for Microchip microcontrollers and digital signal controllers. Cooled CCD Camera The QSI 6120 model camera employs an 12mp Sony CCD image sensor. The high senstivity, wide dynamic range, dual read rates, low noise performance and internal 5 or 8-position color filter wheels make the QSI 6120 ideally suited to a broad range of demanding scientific, medical, astronomical, and industrial imaging applications. The 6120 camera system is supported by industry leading astronomy and microscopy image acquisition software plus a full camera control API is available for creating custom Windows or Linux applications. The 4250×2838 sensor in the QSI 6120, shown to the left approximately life size, provides extremely high resolution with its 3.
The compact design and internal color filter wheel of the QSI 6120ws allows unvignetted, filtered images even with very fast optical systems. The QSI 6120 camera employs a Sony ICX834 12 megapixel interline transfer CCD image sensor with microlens technology. The sensor has antiblooming protection and a fast electronic shutter. Micro lenses cover the surface of the CCD to focus the light into each 3. 1µm pixel to increase optical response. See the Specifications tab below for additional details. Two separate analog processing chains, providing dual read rates, allow the QSI 600 Series to meet two seemingly incompatible imaging goals.
High Speed mode has a read rate of 8MHz providing high speed reads at multiple frames per second. Each camera’s timing and voltages are carefully set during manufacture to ensure maximum Charge Transfer Efficiency, and to minimize charge injection and other secondary noise sources. Sophisticated mixed-signal design practices are utilized throughout the camera. This permits a very compact design while eliminating interference from conducted and radiated noise. ROHS compliant multi-layer circuit boards and surface-mount components are used exclusively.
A unique circuit board stacking methodology eliminates interconnecting wires that could reduce reliability. A carefully designed and isolated switching power supply generates all of the voltages needed to operate the camera from a single 12VDC power source. Low noise design practices and advanced filtering techniques completely eliminate any measurable impact on camera noise performance. Arguably, the most important aspect of a CCD camera design is the video processing subsystem. This is where almost all of the camera’s performance characteristics are established. The 600 Series video processing begins with a very low noise, precision preamp to accurately amplify the microvolt level pixel signal from the CCD image sensor.
The Read Noise contributed by this entire subsystem is exceedingly small. 30 of the combined read noise of a typical image sensor. The low read noise and carefully chosen camera gain yield excellent Dynamic Range. Linearity is also outstanding, limited only by the CCD image sensor itself. Small enough to practically hide behind a CD-ROM, the medium format QSI 600 Series family sets new standards for full-featured, high performance scientific CCD cameras. The striking appearance, refined design and superior fit and finish only hint at the advanced technical performance lurking inside.
