ITR3CMOS09000KMA 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.

In-depth Product Overview

Advanced dual-stage TEC cooling system

Dual-stage thermoelectric cooling (TEC) lowers the sensor temperature 35–45 °C below ambient, dramatically suppressing dark current. At an operating temperature of -20 °C, typical dark current stays below 0.003 e⁻/pixel/sec, enabling multi-hour exposures without noticeable thermal noise. Precise temperature control and an anti-condensation design ensure stable operation across demanding environments.

High-performance back-illuminated sensor technology

Sony back-illuminated CMOS sensors deliver exceptional quantum efficiency and minimal read noise. The back-illuminated structure places the photodiode above the circuitry to maximize photon collection, maintaining high signal-to-noise ratios in low light. Optimized electronics and multi-gain modes reduce read noise to as low as 1 e⁻, preserving fine detail. Pixel sizes from 2.4 µm to 4.63 µm strike the ideal balance between resolution and sensitivity.

Assured research-grade imaging

The camera supports 8-bit, 12-bit, and 16-bit output with up to 75 dB dynamic range and signal-to-noise ratios of 50 dB, meeting stringent scientific requirements. Exposure control spans from 50 µs to several hours, capturing fast-changing phenomena and enabling long integrations for deep-sky targets. A large DDR buffer paired with the USB 3.0 interface guarantees lossless transfer of high-resolution data for reliable analysis.

Industrial-grade reliability

A CNC-machined aluminum housing integrates efficient heat dissipation to maintain stability during long sessions. The anti-condensation window prevents moisture build-up at low temperatures. USB 3.0 single-cable power simplifies integration, while an optional 12 V auxiliary supply further stabilizes cooling performance. With an operating range of -10 to 50 °C and low power consumption, the camera excels in unattended, long-term observation.

Comprehensive software ecosystem

SDKs for Windows, Linux, and macOS work seamlessly with mainstream languages such as C/C++ and Python, expediting integration into existing scientific systems. Companion software delivers complete camera control, acquisition, processing, and analysis tools. Standardized interfaces simplify embedding within telescopes, spectrometers, microscopes, and other research instruments, providing a reliable imaging backbone for scientific exploration.
