Four channels: R, G, B and NIR
Currently the only industrial-grade 4-CCD line scan camera on the market,
features a beam-splitter prism with hard dichroic coatings
incorporating four precisely-aligned, pixel-to-pixel CCD sensors. The
incoming light is split into 4 spectral bands (RGB + NIR) with each sensor
seeing, simultaneously and through the same optical path, exactly the
same point on the object at all times.
By adding an NIR sensor, the new camera makes it possible to identify
an even-wider set of defects on inspected objects as both surface and
under-surface can be examined.
The LQ-200CL's prism technology eliminates the
complex alignment and encoding issues associated with tri-linear line
scan cameras, (especially those related to off-axis viewing), variations
in conveyor speed, surface undulations or objects that roll or move as
they pass through the camera's field-of-view, saving time
and increasing efficiency.
of the four sensors provides 2048 linear pixels (14 µm square) and
runs at a maximum scan rate of 19048 lines-per-second.
Built-in pre-processing functions such as flat-field correction that can
be set individually for all four channels
optimisation through the built-in gamma/gain correction functionality.
Each channel can be set individually
automatic white balance
shuttering with individual controls for each channel
circuit that improves signal-to-noise ratio by up to 3 dB (situation-dependent)
without losing spatial resolution
control model for substantially increased flexibility as one of three
shutter operating modes
shutter sensitivity via the binning function that combines the values
of two adjacent pixels at the output stage
and installation aid with built-in test-pattern generator
Excellent temperature management through a ridged body that dissipates
heat and thereby optimises image quality
with all other JAI line-scan cameras, the LQ-200CL has undergone extensive
shock ( to 50 G) and vibration testing (to 3 G) to maximise its ability
to withstand the rigors of industrial environments.
