IUA Series

Product Introduction

The IUA series is designed for general industrial inspection and scientific imaging, with resolution coverage from 0.39MP to 45MP. It provides multiple models from small to large sensor formats, offering global shutter (GS) or rolling shutter (RS) solutions by application, as well as visible light, Near-Infrared (NIR) and ultraviolet (UV) specialized wavelength models (depending on model).

For transmission and synchronization, IUA primarily uses USB3.0 for real-time acquisition, with some models providing 10GigE for long-distance and high-bandwidth transmission. The camera body is equipped with 7-Pin I/O (optically isolated input/output + configurable GPIO), facilitating coordination with trigger sources, light sources, motion control and other peripherals.

The software ecosystem is comprehensive, including ToupView software and cross-platform SDK (Windows / Linux / macOS), compatible with DirectShow / TWAIN and other third-party interfaces for secondary development and system integration.

In-Depth Product Introduction

Advanced Sensor Technology Platform

The IUA series incorporates industry-leading Sony Pregius/Pregius S series and GPixel BSI back-illuminated sensors, covering the broad spectrum from visible light to ultraviolet and near-infrared wavelengths. The BSI architecture significantly enhances photon collection efficiency with dark current levels as low as 0.03-0.3 e-/s/pix, ensuring clear image acquisition even in low-light environments. The diverse sensor selection ranges from high-speed low-resolution to ultra-high-resolution 45 MP configurations, meeting the precision imaging requirements of various application scenarios.

Global Shutter High-Speed Imaging Technology

Selected models feature global shutter functionality that effectively eliminates motion blur and distortion of high-speed moving objects, making them particularly suitable for industrial inspection and motion analysis applications. Frame rates achieve hundred-level high-speed acquisition in 2-8 MP resolutions, with further enhancement possible through ROI and binning modes. Support for exposure times as short as 6 µs ensures capture of instantaneous dynamics, providing reliable performance for high-speed production line inspection, moving target tracking, and similar demanding applications.

Specialized Spectrum Imaging Solutions

The unique spectral imaging design enables the IUA series to excel in specialized wavelength detection applications. UV models employ glass removal technology to dramatically enhance ultraviolet wavelength response, while NIR models achieve near-infrared quantum efficiency exceeding 90% through sensor optimization and specialized coatings. This broad spectral coverage capability provides unique advantages in semiconductor defect detection, biomedical fluorescence imaging, security surveillance, and similar fields, offering multi-purpose functionality while reducing system complexity.

Industrial-Grade Interface and High-Reliability Design

The cameras feature comprehensive industrial-grade I/O interfaces including one optically isolated input, one optically isolated output, and programmable GPIO supporting external triggering and flash synchronization functions. The 7-pin aviation connector design ensures connection reliability in vibrating environments. The CNC aluminum alloy unibody construction utilizes fanless passive cooling design with power consumption below 3 W, enabling continuous 24/7 stable operation even in harsh industrial environments.

Comprehensive System Integration Support

The cameras provide dual interface options of USB 3.0 and 10GigE to meet different transmission distance and bandwidth requirements. Professional ToupView/ToupLite software supports comprehensive platform compatibility including Windows, Linux, macOS, and Android. Rich SDK interfaces encompass C/C++, C#/VB.NET, Python, Java, DirectShow, and Twain, significantly simplifying secondary development workflows. Standard C-mount lens compatibility combined with the compact 38×38×33 mm dimensions facilitates integration into various automation equipment and scientific instruments.
