MTR3CMOS Series

Product Introduction

The MTR3CMOS series are C-mount USB3.0 multi-channel CMOS cameras designed for simultaneous imaging requirements of multi-color fluorescence and complex optical paths. The cameras integrate multi-channel color separation optics (model dependent) internally, capable of separating different wavelength/color channels from samples and acquiring them synchronously, significantly improving imaging efficiency while avoiding timing errors from sequential switching. Equipped with high-sensitivity, low-noise CMOS sensors and built-in Ultra-Fine image processing engine, they deliver high signal-to-noise ratio images even under weak signal conditions. USB3.0 high-bandwidth links and built-in buffering ensure stable transmission of large multi-channel data volumes. Each channel supports independent exposure/gain/ROI/bit depth settings, facilitating fine optimization according to spectral lines and brightness differences. The housing features precision aluminum alloy CNC construction for long-term stable and reliable operation. Includes ToupView/ToupLite and cross-platform SDK (Windows / Linux / macOS / Android) for easy system integration and secondary development.

In-depth Product Overview

Sony Exmor scientific CMOS technology

Sony's latest Exmor CMOS architecture integrates column-parallel A/D converters and digital noise cancellation to deliver ultra-low read noise with high-speed throughput. Optimized pixel structures and circuit design elevate quantum efficiency and dynamic range, maintaining exceptional imaging performance under low-light conditions. Pixel sizes from 1.7 µm to 16 µm cover both high-resolution detail capture and high-sensitivity requirements.

High-efficiency dual-stage TEC system

A precisely engineered dual-stage thermoelectric cooling (TEC) system keeps the sensor 40 °C below ambient with stable temperature control. Efficient thermal management and PID regulation allow real-time monitoring and software adjustment. The deep cooling dramatically reduces CMOS dark current and thermal noise, substantially improving signal-to-noise ratios during long exposures for scientific imaging.

Innovative anti-condensation sealed design

A unique sealed chamber combined with advanced anti-condensation measures prevents frosting or fogging when the sensor is deeply cooled. Specialized desiccants and inert gas filling isolate external moisture, while the optical window features anti-fog coatings to maintain clarity even under high humidity or rapid temperature shifts. This ensures reliable imaging during extended operation.

Precise exposure and multi-mode triggering

Exposure control spans from 0.1 ms to 1 h with selectable 8-, 12-, or 16-bit output, covering fast dynamic capture through long, low-light integrations. Trigger options include software, external hardware, and burst triggering, enabling accurate multi-camera synchronization and complex experimental timing. The high-speed USB 3.0 interface delivers 5 Gbps bandwidth with USB 2.0 backward compatibility for excellent system integration.

Comprehensive hardware and software integration

The built-in Ultra-Fine hardware ISP engine provides accurate color reproduction and detail enhancement. Professional ToupView/ToupLite software bundles image acquisition, processing, measurement, and reporting tools. Extensive SDK coverage spans Windows, Linux, macOS, and Android with interfaces for C/C++, C#/VB.NET, Python, Java, DirectShow, and TWAIN. A CNC-machined aluminum body with vibration-damping fan design maintains efficient heat dissipation while minimizing mechanical vibration for long-term stability.
