ITR3CMOS Series

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 two-stage TEC cooling

Utilizes two-stage semiconductor TEC cooling to lower the sensor 35–45 °C below ambient, dramatically suppressing dark current. At -20 °C, typical dark current is under 0.003 e⁻/pixel/sec, enabling hours-long exposures without noticeable thermal noise. Precise temperature control and anti-condensation design ensure stable operation across environments.

High-performance BSI sensors

Equipped with Sony back-illuminated CMOS sensors offering very high quantum efficiency and ultra-low read noise. The BSI architecture places the photodiode above circuitry to maximize photon collection, delivering high SNR even in low light. Optimized electronics and multi-gain modes reduce read noise down to 1 e⁻, preserving fine detail. Pixel sizes from 2.4 µm to 4.63 µm balance resolution and sensitivity.

Scientific-grade imaging quality

Supports 8-bit/12-bit/16-bit output with up to 75 dB dynamic range and SNR up to 50 dB to meet rigorous research needs. Exposure spans from 50 µs to several hours, capturing fast events and long deep-sky integrations. Large onboard DDR plus USB3.0 high speed ensures lossless transfer of high-resolution frames, protecting scientific data integrity.

Industrial-grade reliability

CNC aluminum housing with efficient thermal design ensures stability during long runs. Anti-condensation window prevents moisture at low temps. USB3.0 single-cable power simplifies integration; optional 12 V auxiliary input provides steadier cooling. Operating range -10 to 50 °C with low power suits unattended long-term observation.

Comprehensive software ecosystem

SDK support across Windows, Linux, and macOS with C/C++ and Python enables quick integration into research systems. Companion software offers full camera control, acquisition, processing, and analysis. Standardized interfaces allow easy embedding into telescopes, spectrometers, microscopes, and other scientific instruments for reliable imaging solutions.
