    Details

    The GL2048L camera provides high-resolution line capture using 2048 pixels on 10-micron pitch for both Machine Vision and for Optical Coherence Tomography with high QE in the 1 to 1.6 micron wavelength range.  The camera covers the line rate range from 100 to >76,000 lines per second via 12-bit base Camera Link® digital interfaces providing flexibility. It can also be externally triggered over the interface to set both the line rate and exposure time via the frame grabber CC1 signal.
