JAI introduces two new prism-based industrial color/near-infrared line scan cameras in the Sweep+ Series: SW-4000T-10GE and SW-4000Q-10GE.
Sweep+ SW-4000T-10GE (R-G-B)
Sweep+ SW-4000T-10GE is a prism-based color line scan camera equipped with three CMOS sensors and a super-fast 10GBASE-T GigE Vision Interface including backwards compatibility to N-BASE-T and 1000BASE-T GigE Vision interfaces.
The Sweep+ SW-4000T-10GE offers a maximum resolution of 4096 pixels (4k) per channel/line, and in combination with the 10GBASE-T interface, the camera provides RGB output at a maximum line rate as high as 97 kHz (97,000 scan lines/second). YUV color data can be output at up to 145 kHz. Using sensor Region-of-interest (ROI) the camera can output data at even faster line rates. Setting the camera at for example 2112 pixels the scan rate can be increased to as much as 183.400 lines/s.
The combination of 3-CMOS prism color line scan technology with a 10GBASE-T (10Gbit/s) interface, not only makes this camera the world’s first product of its kind, but also the world’s fastest prism-based RGB color line scan camera.
Sweep+ SW-4000Q-10GE (R-G-B + NIR)
The new Sweep+ SW-4000Q-10GE is equipped with four prism-mounted CMOS sensors to capture simultaneously red, green, blue, as well as the near infrared spectral wavebands for both high color accuracy and multi-spectral analysis via the NIR channel.
Just like the SW-4000T-10GE model, the SW-4000Q-10GE camera offers a maximum resolution of 4096 pixels (4K) per channel/line, and in combination with the 10GBASE-T interface, the camera provides RGB + NIR output at up to 72 kHz (72,000 lines per second) over dual 10 GigE streams. The dual stream configuration supports 8-bit or 10-bit output per channel.
The SW-4000Q-10GE also offers a single-stream option using the RGBa8 format where the NIR data is provided via the alpha channel. In this configuration, the camera can operate at up to 73 kHz with 8-bit-per-channel output. A third output option, capable of up to 74 kHz at full 4K resolution, includes 8-bit YUV color data on one stream combined with 8-bit or 10-bit NIR data on a second stream.
The prism-based technology used in both the SW-4000T-10GE and the SW-4000Q-10GE eliminates off-angle viewing problems, spatial compensation issues, 3D cylindrical offsets, and other problems that can affect image quality when using trilinear color line scan technology.

10GigE interface with backwards compatibility, covering the slowest to the fastest running vision applications:
Via intelligent auto-negotiation technology the new Sweep+ cameras offer automatic backwards compatibility to N-BASE-T (5 Gbps and 2.5 Gbps) and the traditional 1000BASE-T (1 Gbps) GigE Vision output, for customers running vision applications on these lower-speed Ethernet standards. Therefore, the new color/NIR line scan cameras cover multiple Ethernet configurations making them suitable for the slowest to the fastest running vision applications where color or color+NIR line scan technology is being applied as the inspection method.
Applications include:
High speed print and currency inspection
3D inspection of bottles, cans, or other cylindrical items.
Food sorting (vegetables, olives, fruit tea leaves etc).
Waste sorting (colored plastic or glas).
Sheet metal and coin inspection.
Granular inspection.
User-selectable pixel size and horizontal/vertical binning for maximum flexibility in pixel settings:
The SW-4000T-10GE and the SW-4000Q-10GE cameras offer two user-selectable pixel sizes – a 7.5 x 7.5 µm mode (Mode A) with fast responsivity for applications that need it, and a 7.5 x 10.5 µm mode (Mode B) when rectangular pixels and a deeper well with better dark SNR are preferred.
Also included in the sensors are a multi-line design that not only supports two-pixel horizontal binning, but also gives each of the color channels (and NIR channel) two lines in the vertical direction (direction of travel) to support 1 x 2, 2 x 1, or 2 x 2 binning. In total, this gives 8 different pixel size settings for maximum flexibility.
Built-in color space conversion:
Advanced color imaging systems often require a specific type of color representation to efficiently perform their intended function. RGB values must be converted to these different representations – also called color spaces – as part of the application.
The new cameras feature a programmable color matrix circuit with built-in color conversions from standard RGB output to sRGB, Adobe RGB, HSI and CIE XYZ color spaces. Customers can also program their own custom RGB conversions using the color matrix circuit. This broad range of color space options (in 4k line scan cameras) is only available from JAI.
Precision Time Protocol (PTP):
The Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a computer network. With the PTP feature, image capture can take place at the same time for all linked cameras. All synchronous images have the shared timestamp, making image analysis easier.
Direct connection to encoders from the camera:
The cameras provide four separate input lines plus built-in algorithms to support a direct connection from up to two separate rotary encoders. Functions are provided in the software control tool to let users easily define the inputs and the synchronization relationship between the encoder and the camera.
Additional features:
The SW-4000T-10GE and the SW-4000Q-10GE cameras come with a wide range of additional features in keeping with the high reliability and high image quality typical of JAI cameras. These include:
- Analog and digital gain adjustment.
- Region-of-interest (ROI) settings for even higher scan rates.
- Black level adjustment.
- Manual, one-push, and automatic white balancing.
- Multiple color temperature presets.
- PRNU/DSNU correction.
- Color shading correction.
- Chromatic aberration correction.
- Line counter/Time-stamp/CRC insert information.
- Horizontal image mirroring.
- Large variety of trigger options.
- High shock & vibration rating (50 G, 10 G respectively).
