JAI has released two new multispectral (R-G-B-NIR) models in the company's Sweep+ Series of prism-based line scan cameras. The SW-8000Q-10GE and SW-8000Q-SFP are the industry's first prism-based line scan cameras to offer 8K (8192) pixel resolution per line.
Both new models are equipped with four 8K CMOS sensors mounted on a four-way dichroic prism that separates the incoming light into red, green, blue, and near infrared (NIR) wavelengths providing both high color accuracy and multispectral analysis via the NIR channel.

This 30-minute webcast examine the key advantages of prism-based cameras for certain types of line scan applications.
Sweep SW-8000Q applications in machine vision systems:
The new SW-8000Q-10GE and SW-8000Q-SFP models are particularly suited in machine vision applications where the speed or position of the inspected objects is constantly varying.
Examples include objects that roll or wobble on conveyor belts, free-falling objects, and even vibrations or undulations in web-based rolls. Among the typical applications are:
Belt/bulk sorting and inspection of fruits, vegetables, or other loose items.
Quality inspection of pharmaceutical products
like for example blister packages.
Steel, textile, paper, or foil inspection where vibrations or undulations in the web are common.
Free-fall inspection of grains, coffee beans
nuts, or other similar items.
Recycling applications using belts to sort
various loose items like plastic.
Any other continuous motion applications like
road inspection, PCB inspection and others.
Product feature highlights:
- Industry’s first 4-CMOS prism-based RGB + NIR line scan cameras with 8K pixel resolution.
- Simultaneous imaging of visible and NIR light.
- 8192 pixels (8K) per line for high resolution images.
- For high speed applications: Up to 36.0 kHz at full resolution (36,000 lines/s).
- 3.75 x 5.78 µm rectangular pixels in a two-line arrangement supporting horizontal pixel binning, vertical pixel binning, or both for increased sensor sensitivity.
- 10GBASE-T copper interface (SW-8000Q-10GE) and 10GBASE-R fiber interface (SW-8000Q-SFP) provide high-speed, GenICam-compliant GigE Vision output.
- 10 GigE interface with backwards compatibility to lower speed Ethernet standards. (only when running over copper interface).
- Vertical dual-line binning, 2x horizontal binning, or both.
- Built-in color space conversions.
- Direct encoder connection to the camera.
- Precision time protocol support (IEEE 1588)

The advantage of 4-CMOS prism cameras compared to quadlinear cameras:
Unlike quadlinear cameras which must use compensation algorithms to account for the spacing in their multi-line sensors, the four 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 color fringes or "halos" in images from non-prism cameras due to constantly changing parallax and keystone effects.
10 GigE interface with backwards compatibility to lower speed Ethernet standards for maximum flexibility:
The SW-8000Q-10GE features a 10 GigE interface that also supports backwards 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.
Single-stream and dual-stream data transmission of visible and NIR images:
In both new models, the multispectral image data can be transmitted as a single combined stream using the RGBa8 pixel format, or in a dual-stream format with RGB or YUV data on one stream and NIR images on the other. The dual stream configuration supports 8-bit or 10-bit output per channel with a maximum line rate of 36 kHz (36,000 lines per second) for 8-bit RGB + NIR data or 37 kHz (37,000 lines per second) for YUV + NIR data. For single-stream RGBa8 output the maximum line rate is also 37 kHz.
Pixel binning for increased sensor sensitivity and Region-of-Interest (ROI) function for faster line rates:
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 for increased sensor sensitivity in applications with low light conditions. Users can also adjust the line width to less than 8192 pixels using region-of-interest (ROI) settings, which increases the line rate.
Build-in color space conversion:
The SW-8000Q-10GE and SW-8000Q-SFP have a built-in color conversion function that allows the color output to be provided in HSI or CIEXYZ color format if needed, as well as offering conversions from standard RGB to the sRGB or Adobe RGB color spaces, or even to a user-defined custom RGB conversion matrix.
Precision Time Protocol (PTP):
The cameras also support the precision time protocol (IEEE 1588) for multi-camera networked configurations and can be connected directly to rotary encoders for synchronization with conveyor belts and other motion systems.
GigE Vision output via optical fiber connection (SFP+) for longer cables and low data transmission delay:
The SW-8000Q-SFP model features an “Enhanced Small Form-factor Pluggable” (SFP+) interface which delivers GigE Vision output via optical fiber 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.
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-8000Q-10GE and SW-8000Q-SFP can be ordered with two different lens mount options – a Nikon F-mount or an M52 mount.
