3-CCD colour cameras provide many advantages over the simpler tri-linear color cameras, including that all three colour bands view the object through the same optical plane, through the prism block
Although Jai's principal business is developing, manufacturing and marketing area scan cameras, the company also has a long-standing tradition of making specialised line scan cameras.
One of these specialisations is within the field of prism-based colour cameras.
The new CV-L107CL carries this tradition on, and provides increased performance in a smaller package.
The CV-L107CL was designed to meet these market requirements: a high performance, high speed 3-CCD line scan camera packaged in the smallest possible housing, using a standard interface.
Jai says it has fulfilled these requirements by designing a camera with 3x 2048 pixels resolution, 19kHz line rate, flat-field and shading correction, and the option of individual exposure time for each of the R, G and B channels, all packaged into a cube that measures 90x90x90mm.
The CV-L107CL uses the standard Camera Link interface.
The user can select a 24-bit mode, which requires only one CL connector (base configuration) or a 30-bit mode, requiring two CL connectors (medium configuration).
The CV-L107CL can be ordered with a Nikon F-mount or an M-42 lens mount.
3-CCD colour cameras provide many advantages over the simpler tri-linear color cameras: In a 3-CCD colour camera, all three colour bands view the object through the same optical plane, through the prism block.
There is no physical/temporal offset between the colour planes, as is the case in tri-linear solutions.
Because 3-CCD cameras only have one optical plane, they can be used in angles of incidence other than perpendicular to the object being viewed.
This is a major optical challenge with tri-linear cameras.
The dichroic hard coatings used on the prism parts of the 3CCD cameras, separating the spectral bands, are well defined and do not have any lifetime limitations.
Tri-linear sensors, in contrast, use dyes that are not stable over the long term, and that do not have sharp cut-off.
The CV-L107CL will be featured at the Vision Show in Stuttgart, 8-10 November 2005.
The CV-L107CL will be available in production quantities in 4Q2005.
