2048R InGaAs High Speed Linescan Camera

Details

The new GL2048R camera delivers line capture rates of 10,000 to 147,000 lines per second for Spectral-Domain Optical Coherence Tomography while providing high QE in the 1 to 1.6 micron wavelength range.   This 2048-pixel camera provides high-resolution imagery with 12-bit depth over the Medium Camera Link® digital interface.  It can also be externally triggered over the interface to set both the line rate and exposure time via the frame grabber CC1 signal.
