With it's 5 Megapixel image sensor, it can be used in with 5 Megapixel lenses even in ultra-high resolution mode. There is no need for ultra-high resolution lens optics. This is achieved by using a piezo element to shift the sensor by fractions of a pixel both horizontally and vertically in quick succession. This allows a sequence of images to be captured which are then interleaved into the high resolution image on a host PC.
The colour version is particularly versatile. By using the sensor as a standard imager, the field of interest can be quickly located before switching to ultra-high resolution mode. Also, by setting the pixel shift to be one pixel rather than a fraction of a pixel, the camera can operate at the sensor’s 5 Megapixel resolution to provide full RGB output for each pixel without colour fringing. In this mode the camera gives performance equivalent to a 3-CCD device from a single sensor.
The monochrome version offers a frame rate of 0.516fps at a resolution of 125 Megapixels. 1.43fps can be achieved at 45 Megapixels and 15fps at 5 Megapixels. The colour version also has a frame rate of 1.43 fps at 45 Megapixel resolution and 3.12fps in RGB mode.
Data is transferred via CameraLink Base at 8 or 10 Bits. To facilitate easy integration and to generate high-resolution images STEMMER IMAGING provides sample applications with source code for Teledyne DALSA X64-CL and Xcelera-CL PX4 image capture cards, but can advise on the use of other frame grabbers.
