CTR3CMOS Series

Product Introduction

The CTR3CMOS series is designed for low-light and long-exposure scenarios, featuring Sony Exmor and other high-performance CMOS sensors with resolution coverage from 0.39–20 MP and sensor formats from 1/2.9″–4/3″. Built-in thermoelectric cooling (TEC) and closed-loop temperature control reduce sensor operating temperature by approximately 5–10 °C below ambient temperature. Combined with anti-fogging structure, it effectively suppresses dark current and condensation, ensuring imaging stability and consistency during low-temperature, long-duration acquisition.

Data links support USB3.0 (5 Gbit/s) and GigE (1 Gbit/s, model dependent), maintaining stable throughput under high-speed/long-distance transmission. Supports 8/12/16-bit data output (model dependent), ROI/windowing and multi-gain modes. Cameras provide free-running, software/hardware triggering and multi-camera synchronization, with industrial-grade I/O for integration with external light sources, motion platforms or production line signals. Maximum exposure can reach approximately 300 s, suitable for chemiluminescence, fluorescence, spectroscopy and other weak signal applications.

Includes ToupView software and provides cross-platform SDK (Windows / Linux / macOS) for secondary development and system integration, meeting diverse requirements for scientific research, industrial inspection and general scientific imaging.

Deep Product Overview

Stable single-stage TEC cooling

Uses single-stage thermoelectric cooling that typically drops the sensor temperature about 10 °C below ambient, effectively suppressing dark current and improving long-exposure stability. Precise temperature control with anti-condensation design keeps it running reliably across environments, ideal for low-light imaging and unattended research observations.

High-performance backside-illuminated sensor

Equipped with Sony backside-illuminated CMOS sensors that deliver very high quantum efficiency and ultra-low read noise. Dual-gain modes and optimized electronics bring read noise down to 1 e⁻, preserving image quality in low light or long exposures. Pixel sizes from 2.4 µm to 4.63 µm balance high resolution with high sensitivity, giving a strong foundation for weak-signal capture.

Professional-grade imaging assurance

Supports 8-bit/12-bit output; 12-bit depth supplies ample gradation for research analysis. Typical dynamic range reaches 75 dB with SNR above 50 dB, meeting high-contrast scientific imaging needs. Flexible exposure control from 50 µs to several hours captures both fast events and deep-sky long exposures. The USB3.0 interface and large onboard buffer ensure stable delivery of high-resolution frames.

High-reliability industrial design

CNC metal housing with efficient thermal management keeps temperatures stable during long runs. The anti-condensation window prevents frosting at low temperatures, while the all-metal body offers strong electromagnetic shielding to reduce interference. Operating range is -10 to 50 °C, supporting long-term stability for around-the-clock research observations.

Complete software ecosystem support

SDKs are available for Windows, Linux, and macOS, supporting C/C++, Python, and other mainstream languages for fast integration into existing research systems. Standardized interfaces and complete documentation make it easy to embed the camera into telescopes, spectrometers, microscopes, and other scientific equipment. The single-cable USB3.0 power design simplifies deployment, with optional 12 V auxiliary power for even steadier cooling.
