Hamamatsu C11440-52U Scientific-Grade Board-Level CMOS Camera

Overview

The Hamamatsu C11440-52U is a high-performance, board-level scientific CMOS camera engineered for demanding optical imaging applications requiring high quantum efficiency, low noise, and flexible temporal resolution. Built around the FL-400 second-generation scientific CMOS sensor, it delivers photon detection sensitivity optimized for visible-to-near-UV wavelengths—achieving >70% quantum efficiency at 600 nm. Its 2048 × 2048 pixel array features uniform 6.5 µm pixels, yielding a 13.3 mm × 13.3 mm active area ideal for integration into compact optical systems such as microscopes, spectrographs, and automated inspection platforms. Unlike consumer-grade sensors, the FL-400 architecture incorporates correlated double sampling (CDS), on-chip analog-to-digital conversion, and advanced pixel design to minimize fixed-pattern noise and dark current—enabling quantitative intensity measurements with high reproducibility across extended acquisition sequences.

Key Features

• Scientific CMOS sensor (FL-400) with peak QE >70% at 600 nm and broad spectral response from 200 nm to 1100 nm
• Low-noise readout: 2.3 e⁻ rms (33 ms exposure, typical), 1.6 e⁻ median—critical for low-light quantification in fluorescence and bioluminescence
• Flexible frame rate range: 30 fps at full resolution (2048 × 2048) up to 25,655 fps in region-of-interest (ROI) mode (512 × 8), supporting both static imaging and ultrafast dynamic capture
• 16-bit A/D conversion with 18,000:1 dynamic range (calculated from full-well capacity of 30,000 e⁻ and mean read noise)
• Compact mechanical footprint (90 mm × 90 mm × 25 mm) and lightweight design facilitate OEM integration into space-constrained instruments
• USB 3.0 interface ensures high-bandwidth data transfer (>350 MB/s sustained) with deterministic latency and plug-and-play compatibility under Windows and Linux environments
• Programmable triggering and synchronization: four external trigger modes (edge, level, sync-readout, start) plus three user-configurable timing outputs for precise coordination with lasers, shutters, or motion stages
• Onboard image processing including 2×2 and 4×4 binning, centered subarray readout, and exposure-controlled blanking to suppress artifacts during long integrations

Sample Compatibility & Compliance

The C11440-52U is designed for use with standard C-mount optics and supports a wide range of sample illumination modalities—including transmitted light, epi-fluorescence, structured illumination, and X-ray scintillator coupling (e.g., CsI:Tl or Gd₂O₂S). Its thermal management architecture maintains stable dark current below 0.01 e⁻/pixel/s at ≤+35 °C ambient, ensuring consistent performance during multi-hour acquisitions required in genomics or cell biology workflows. The camera complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards for industrial environments. While not certified for medical device use, its deterministic firmware behavior, repeatable gain/offset calibration, and traceable exposure control support GLP-aligned documentation practices. Data integrity is preserved through lossless USB packet transmission and optional metadata embedding (exposure time, temperature, ROI coordinates) in each frame header.

Software & Data Management

Hamamatsu provides the HCImage Live software suite (Windows) and SDKs for C/C++, Python, MATLAB, and LabVIEW—enabling full control over acquisition parameters, ROI definition, trigger sequencing, and real-time histogram analysis. The SDK supports memory-mapped frame buffers and zero-copy DMA transfers to minimize CPU overhead during high-throughput streaming. All acquired images are saved in TIFF or HDF5 format with embedded EXIF-like metadata, facilitating interoperability with ImageJ/Fiji, CellProfiler, and commercial analysis packages. For regulated environments, optional audit-trail logging (user actions, parameter changes, timestamps) can be enabled to align with FDA 21 CFR Part 11 requirements when deployed within validated laboratory information management systems (LIMS).

Applications

• DNA electrophoresis and blot imaging—leveraging high QE and low noise for sensitive ethidium bromide or SYBR Safe detection
• High-content screening (HCS) in drug discovery—supporting multi-well plate imaging with automated focus and exposure optimization
• Live-cell time-lapse microscopy—enabled by fast ROI readout and minimal phototoxicity due to high sensitivity
• Automated wafer inspection—utilizing sub-pixel registration accuracy and distortion-corrected flat-field calibration
• X-ray imaging via scintillator coupling—where high dynamic range and radiation-hardened sensor architecture ensure stable response under pulsed X-ray sources
• Single-molecule localization microscopy (SMLM)—benefiting from precise electron-counting capability and low background variance

FAQ

What is the recommended maximum exposure time for optimal image quality?
For best signal fidelity and minimal fixed-pattern artifact formation, Hamamatsu recommends limiting exposure to ≤100 ms. Longer exposures (up to 30 s) are supported but may introduce white-spot defects due to thermal charge accumulation.
Does the camera support hardware synchronization with external devices?
Yes—the C11440-52U offers four programmable trigger input modes and three independent TTL-compatible output signals, enabling tight synchronization with lasers, shutters, or translation stages.
Is cooling available for extended dark-current suppression?
No—this is an uncooled board-level camera. Stable operation is maintained within 0–40 °C ambient; for sub-0.005 e⁻/pixel/s dark current, active thermoelectric cooling must be implemented externally.
Can the camera be used with third-party microscope software?
Yes—via Hamamatsu’s TWAIN and GenICam-compliant drivers, the C11440-52U integrates seamlessly with Micro-Manager, NIS-Elements, and ZEN Blue.
What lens mount does the camera use?
It features a standard C-mount interface with 17.526 mm flange focal distance, compatible with industry-standard achromatic and apochromatic objectives.
