Basler sprint 2k and 4k Cameras
24 June 2008
Basler Sprint 2k and 4k mono line scan cameras have entered full series production.
Each Sprint is assembled using an optimised production process in a clean room environment. And each camera is subjected to a suite of tests in Basler’s Camera Test Tool (CTT+) to ensure the highest quality. The CTT+ includes calibration routines for the camera's sensor and start-up parameters as well as numerous other tests.
The cameras exhibit good performance in high speed applications or where light is limited. The maximum line rate of the sprint does not decrease at higher resolutions and remains at 140kHz for both the 2k and 4k models. To achieve adequate exposure with the extremely short integration times seen at very high speeds, the Sprint's sensor was designed to have exceptionally sensitive pixels.
Due to its very low noise level, the Sprint provides a very high SNR (signal-to-noise ratio). This means that Sprint cameras can perform well under conditions where most conventional line scan cameras would output a signal that is mainly noise.
The cameras in the Sprint family include features such as an AOI (area of interest) with linear speed increase, shading correction, test images, line stamps, configuration sets, and error condition detection. Two types of shading correction (PRNU and DSNU correction) will let users correct for image variations that may result from optics, lighting, or sensor performance.
The more homogeneous behaviour provided by shading correction can be a major advantage for many vision applications. Also a time delayed Line Sum feature can double the camera’s sensitivity and increase the SNR by up to 3dB. This is achieved by using the two lines in the sensor to scan each area on the object twice and then combining the collected information.
