JAI has introduced two additional 8K models in its Sweep+ Series of prism-based line scan cameras.
The SW-8000T-10GE and SW-8000T-SFP are 3-CMOS prism-based line scan cameras providing three-channel (R/G/B) colour image capture at 8K (8192) pixel resolution per line. This follows the launch of two 4-CMOS multispectral (R/G/B/NIR) line scan cameras with 8K resolution earlier this month.
Both new models are equipped with three 8K CMOS sensors mounted on a three-way dichroic prism that separates the incoming light into red, green, and blue wavebands providing high colour accuracy for line scan applications.
Unlike trilinear cameras which must use compensation algorithms to account for the spacing in their multi-line sensors, the three prism-mounted sensors are precisely aligned to a common optical path. Because of this, the prism cameras are not affected by vibrations and speed variations typical of objects on conveyor belts or in free-fall sorting, which can cause colour fringes or “halos” in images from non-prism cameras due to constantly changing parallax and keystone effects.
The SW-8000T-10GE features a 10 GigE interface that also supports backward compatibility to 5 Gbps, 2.5 Gbps, and 1 Gbps Ethernet standards. The interface can automatically detect the capability of its PC or network connection and adjust accordingly for customers running vision applications on these lower-speed Ethernet standards.
The SW-8000T-SFP model features an “Enhanced Small Form-factor Pluggable” (SFP+) interface which delivers GigE Vision output via optical fibre cables. The SFP+ interface supports very long cables with low latency (low data transmission delay), low data transmission noise, as well as immunity to electromagnetic interference and system crosstalk.
In both new models, the image data can be transmitted as a single RGB stream at up to 49 kHz (49,000 lines per second) for 24-bit (3 x 8-bit) uncompressed RGB output or at up to 37 kHz for 30-bit uncompressed RGB. Alternatively, users can select YUV422_8 or YUV422_8_UYVY formats providing 8K compressed colour output at up to 73 kHz (73,000 lines per second).
The cameras’ 8K sensors feature 3.75 x 5.78 µm rectangular pixels in a two-line arrangement supporting horizontal pixel binning, vertical pixel binning, or both. Users can adjust the line width to less than 8192 pixels using region-of-interest (ROI) settings, which also increases the line rate.
The SW-8000T-10GE and SW-8000T-SFP have a built-in colour conversion function that allows the colour output to be provided in HSI or CIEXYZ colour format if needed, as well as offering conversions from standard RGB to the sRGB or Adobe RGB colour spaces, or even to a user-defined custom RGB conversion matrix.
The cameras also support the precision time protocol (IEEE 1588) for multi-camera networked configurations and can be connected directly to rotary encoders for synchronisation with conveyor belts and other motion systems.
Additional standard features include gain and black level adjustment, manual or automatic white balancing, shading correction, PRNU and DSNU correction, and chromatic aberration compensation.
The SW-8000T-10GE and SW-8000T-SFP can be ordered with two different lens mount options – a Nikon F-mount or an M52 mount.
