SWIR imaging doesn’t have to take up much space.
The iBX-SWU991N / iBX-SWG991N series brings InGaAs SWIR imaging into a compact form factor, with the smallest configuration measuring just 33 × 33 × 38 mm and weighing about 70 g.
Built around the Sony IMX991 sensor, it delivers 400–1700 nm SWIR imaging, 640 × 512 resolution, 5 μm pixels, and Global Shutter.
The compact design makes SWIR easier to integrate into drones, robotics, portable equipment, and space-limited industrial systems.
Small footprint. Full SWIR capability.

A small interface change can make lighting control much easier.
CONTRASTECH light controllers are now available with a custom Ethernet interface.
Compared with the standard version, Ethernet connectivity makes it easier to connect the controller to a PC, PLC or machine vision network for remote parameter control and system integration.
For multi-station inspection lines, this can mean less manual adjustment and simpler system management.
Custom Ethernet versions available.

When lead time matters, waiting weeks isn't always an option.

Our iVASTER Micro LWIR cameras are ready to ship, helping projects move from development to deployment faster.

Despite their compact 26 × 26 mm design, they deliver:
• Up to 640 × 512 @ 50Hz
• Ultra-low 1W power consumption
• Multiple interfaces including USB, SDI, Camera Link, MIPI
• Lens options from 6.6 mm to 75 mm

Designed for UAVs, security, industrial monitoring and thermal integration projects where both size and delivery time matter.

Small details can make a big difference in machine vision integration.
In compact inspection systems, cable routing is often overlooked — but limited space, repeated movement, and unstable connections can affect system reliability.
CONTRASTECH 90° high-flex cables are designed for industrial vision applications, offering:
• Space-saving right-angle design
• High flexibility for moving equipment
• Stable connections for long-term operation
• Multiple interfaces: USB3.0, GigE, 10GigE, CoaXPress, HIROSE
From cameras to complete vision systems, reliable connections help keep production lines running smoothly.

Higher resolution is changing the way AOI systems inspect complex products.
As PCB, semiconductor, and display manufacturing become more precise, AOI systems need to capture more details while maintaining inspection efficiency.
Large-format cameras with high resolution can cover a wider area in a single image, reducing the need for multiple captures and image stitching.
CONTRASTECH AOI solutions support cameras from 12MP to 245MP, with matched telecentric lenses for high-accuracy inspection and measurement.
A practical approach for applications where detail, consistency, and efficiency matter.

When every microsecond matters, every frame counts.
The CONTRASTECH SONICAM CoaXPress High-Speed Camera captures fast-moving events at up to 3600 FPS with an ultra-short 100 ns exposure, revealing details that conventional cameras simply miss.
Powered by CoaXPress-12, it delivers high-speed data transmission, flexible PC-based recording, and reliable performance for motion analysis, manufacturing, impact testing, and scientific research.
Built for engineers who need speed without compromise.
