AlliedVision Alvium G1-812UV GigE Vision CMOS Camera

Overview

The AlliedVision Alvium G1-812UV is a high-performance, compact GigE Vision-compliant CMOS camera engineered for precision machine vision applications in industrial automation, scientific imaging, and quality inspection environments. Built upon AlliedVision’s proprietary ALVIUM® technology platform — featuring a custom-designed ASIC that offloads critical image processing tasks from the host system — the Alvium G1 series delivers deterministic latency, robust packet recovery, and low CPU utilization without compromising on image fidelity or timing control. At its core resides the Sony IMX487 global-shutter CMOS sensor, offering 8.1 megapixels (3328 × 2496) resolution with high quantum efficiency in the ultraviolet-to-visible spectrum (200–700 nm), making it particularly suitable for fluorescence microscopy, UV-curable process monitoring, and spectral analysis where short-wavelength sensitivity is essential. Its GigE Vision interface ensures plug-and-play compatibility with standard Ethernet infrastructure while supporting cable lengths up to 100 m, enabling flexible deployment across distributed inspection stations.

Key Features

• Proprietary ALVIUM® ASIC architecture enabling real-time onboard image preprocessing, including LUT correction, defect pixel correction, and user-defined ROI handling
• Sony IMX487 global-shutter CMOS sensor with high UV quantum efficiency and low dark current (<0.5 e⁻/pixel/s at 25 °C)
• GigE Vision 2.0 and GenICam 3.x compliance, ensuring interoperability with third-party software frameworks such as HALCON, OpenCV, and Matrox Imaging Library
• Dual lens mount support (C-mount and CS-mount) for seamless integration with standard optics, including UV-transmissive lenses
• Compact 29 × 29 × 41 mm housing constructed from anodized aluminum, rated IP30 for dust resistance and optimized for convection cooling
• Industrial-grade operating temperature range (0–50 °C ambient) with extended MTBF (>50,000 hours) verified under continuous operation conditions
• Configurable GPIO (4-pin Hirose HR10A) supporting hardware-triggered acquisition, strobe output, and external synchronization via TTL or LVDS signals

Sample Compatibility & Compliance

The Alvium G1-812UV supports sample illumination across UV-A (320–400 nm), UV-B (280–320 nm), and visible bands, provided appropriate bandpass filters and UV-optimized optics are used. Its sensor package features quartz window encapsulation to maintain transmission integrity below 350 nm. The camera complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) for industrial electromagnetic environments. It meets CE marking requirements under the EU Machinery Directive 2006/42/EC and RoHS 2011/65/EU restrictions on hazardous substances. While not certified for medical device use per IEC 62304, its firmware architecture supports audit-ready logging and deterministic behavior required for GLP-aligned laboratory workflows.

Software & Data Management

The camera integrates natively with AlliedVision’s Vimba X Software Development Kit — a cross-platform (Windows, Linux x86/x64, ARM64), open-source-compatible framework supporting Python, C++, C#, and .NET bindings. Vimba X implements full GenICam feature naming conventions, enabling standardized parameter access (e.g., AcquisitionFrameRate, ExposureTime, Gain) and persistent configuration storage. All firmware updates are digitally signed and applied via secure bootloader protocols. Image metadata includes embedded timestamping (IEEE 1588 PTP optional), sensor temperature readout, and exposure log history — facilitating traceable data acquisition in regulated environments. Audit trails and configuration change logs can be exported in CSV or JSON format for internal QA documentation.

Applications

• Automated optical inspection (AOI) of PCBs, semiconductor wafers, and microfluidic devices under UV excitation
• High-speed inline monitoring of UV-cured adhesives, coatings, and inks in packaging and automotive assembly lines
• Fluorescence lifetime imaging (FLIM) pre-processing in life science research setups requiring precise frame synchronization
• Dimensional metrology using structured light projection with sub-pixel edge detection algorithms
• Multi-camera stereo vision systems deployed in robotic guidance where compact form factor and deterministic trigger response are critical
• Embedded vision nodes in edge AI inference pipelines leveraging onboard ROI cropping to reduce bandwidth to downstream GPUs

FAQ

Is the Alvium G1-812UV compatible with Time-of-Flight (ToF) illumination systems?

No — it employs a global-shutter CMOS sensor optimized for intensity-based imaging, not phase-shift measurement; ToF integration requires dedicated time-of-flight sensors.
Does the camera support Power over Ethernet (PoE)?

Yes — compliant with IEEE 802.3af (Class 0), delivering up to 12.95 W to the camera over Category 5e cabling.
Can I configure multiple Alvium cameras on a single Gigabit Ethernet port?

Yes — via network switch aggregation or NIC teaming; however, sustained multi-camera throughput requires jumbo frames (MTU ≥ 9000) and flow control enabled.
What is the maximum supported cable length for reliable image transmission?

Up to 100 meters using certified Cat 5e or higher shielded twisted-pair cabling under standard GigE Vision specifications.
Is firmware update reversible?

Yes — Vimba X retains prior firmware versions locally and allows rollback through authenticated CLI commands with version signature verification.
