ITR3CMOS01700KPA Low Light Imaging/Semiconductor Cooled Camera
Product Introduction
The ITR3CMOS series is designed for low-light and long-exposure scientific/industrial imaging, featuring Sony Exmor and other high-performance CMOS sensors with dual-stage thermoelectric (TEC) deep cooling architecture. It is optimized for fluorescence/chemiluminescence, spectral/UV detection, semiconductor and material analysis applications. The built-in anti-fogging optical structure and closed-loop temperature control can reduce sensor operating temperature by approximately 40 °C below ambient and stabilize to the set value within minutes (model dependent), ensuring low dark current and noise while maintaining quantum efficiency and imaging consistency.
The camera uses USB3.0 (5 Gbit/s) as the primary link, supporting 8/12/16-bit data output and long-term exposure (typically up to 3600 s, model dependent). It provides free-running, software/hardware triggering and multi-camera synchronization, with industrial-grade I/O for integration with external light sources/motion platforms/acquisition systems. Optional multi-interface versions (such as 10GigE/Camera Link, model dependent) are available to meet different cabling and bandwidth requirements. Includes ToupView software and cross-platform SDK (Windows / Linux / macOS / Android) for easy system integration and secondary development.
