Teledyne Lumenera Lt Series Scientific-Grade CMOS/CCD Cameras for Industrial and Research Imaging

Overview

The Teledyne Lumenera Lt Series represents a family of high-performance, scientific-grade imaging cameras engineered for demanding industrial inspection, life science research, materials characterization, and precision metrology applications. Built upon rigorously validated CMOS and CCD sensor architectures—including ON Semiconductor KAI-29050/KAI-29052 interline-transfer CCDs and Sony IMX-series global-shutter CMOS devices—the Lt Series delivers exceptional photon capture efficiency, low-noise performance, and pixel-level uniformity across its full product portfolio. Each camera is manufactured in Canada under ISO 9001-certified quality control protocols, ensuring batch-to-batch consistency, thermal stability, and long-term calibration traceability. The series supports USB 3.1 Gen 1 interface with sustained bandwidth up to 400 MB/s, enabling reliable real-time acquisition without frame dropping—even at maximum resolution and bit depth. Core measurement principles rely on linear photoresponse, calibrated analog-to-digital conversion (16-bit), and factory-characterized gain/offset tables—making the Lt Series suitable for quantitative intensity analysis, photometric calibration, and compliance-critical workflows such as ASTM E3022 (for aerospace NDT) or ISO 15529 (optical coordinate measuring systems).

Key Features

• Scientific-grade sensor options: Interline-transfer CCD (e.g., KAI-29050, ICX694) and global-shutter CMOS (e.g., IMX253, IMX255) with quantum efficiency up to 95% at peak wavelength (600–650 nm)
• Full-frame resolutions from 2.2 MP to 29 MP; native 16-bit digitization with on-chip correlated double sampling (CDS) and programmable gain
• Uniform pixel pitch (6.5 µm standard across high-resolution models) and large-format sensors up to 35 mm optical format for wide-field microscopy and macro imaging
• USB 3.1 Gen 1 interface with GenICam-compliant protocol stack, supporting asynchronous reset, hardware triggering, and precise exposure synchronization
• Robust mechanical design: aluminum housing with integrated heat-sink, locking USB-C connector, and optional thermoelectric cooling (on select models)
• Compliance-ready firmware architecture: supports metadata embedding (EXIF/XMP), timestamping with µs resolution, and audit-trail-capable configuration logging

Sample Compatibility & Compliance

The Lt Series accommodates diverse optical configurations—from infinity-corrected microscope objectives (e.g., Nikon CFI, Olympus UIS2) to telecentric lenses and custom collimated beam paths. Its 35 mm sensor format enables direct coupling with standard F-mount or M42-thread optics, while smaller-sensor variants integrate seamlessly into OEM machine vision enclosures. All models comply with CE, FCC Part 15, and RoHS directives. For regulated environments, the cameras support GLP/GMP-aligned data integrity practices: exposure parameters, sensor temperature, and firmware version are embedded in image headers; raw data streams remain unaltered during transfer. When used with validated acquisition software (e.g., Lumenera’s INFINITY ANALYZE or third-party HALCON/NI Vision), the system meets FDA 21 CFR Part 11 requirements for electronic records and signatures when deployed with appropriate access controls and audit trails.

Software & Data Management

Teledyne Lumenera provides the INFINITY DEVELOPER SDK—a cross-platform (Windows/Linux/macOS), C++/C#/Python-compatible API with full GenICam v2.3 and USB3 Vision support. The SDK includes real-time histogram analysis, region-of-interest (ROI) binning, flat-field correction tools, and hardware-accelerated Bayer demosaicing. Image data is output in lossless TIFF, FITS, or vendor-neutral HDF5 formats—preserving 16-bit dynamic range and metadata fidelity. Batch acquisition workflows can be scripted with deterministic timing, synchronized to external TTL triggers or encoder pulses. For enterprise integration, the SDK supports DICOM export (with modality-specific SOP classes) and OPC UA server interfaces—enabling direct ingestion into LIMS or MES platforms without intermediate file handling.

Applications

• High-magnification digital pathology: whole-slide imaging at sub-micron resolution using 29 MP models with motorized stage synchronization
• Automated optical inspection (AOI) in semiconductor packaging: defect detection via multi-spectral illumination and pixel-accurate registration
• Time-lapse fluorescence microscopy: low-dark-current CCD variants enable long-exposure quantification of weakly expressed GFP-tagged proteins
• Metrology-grade dimensional measurement: calibrated pixel scale (µm/pixel) traceable to NIST standards, supporting ISO 10360-7 verification
• Aerospace component NDT: high-dynamic-range imaging of turbine blade surface anomalies under structured light projection
• Remote sensing calibration: onboard non-uniformity correction (NUC) and radiometric linearity validation per ISO 15739

FAQ

What sensor technologies are available in the Lt Series?

The Lt Series integrates both interline-transfer CCDs (e.g., ON Semiconductor KAI-29050, Sony ICX694) and global-shutter CMOS sensors (e.g., Sony IMX253, IMX255), selected based on application-specific trade-offs between read noise, full-well capacity, and shutter type.
Is hardware triggering supported?

Yes—all Lt models feature configurable TTL-compatible input/output lines for external trigger synchronization, exposure gating, and strobe control with jitter < 1 µs.
Can I perform radiometric calibration with these cameras?

Absolutely. Factory-provided flat-field and dark-frame datasets, combined with 16-bit linear response and documented QE curves, enable NIST-traceable radiometric calibration per ISO 15739 Annex B.
Does the SDK support Linux-based embedded systems?

Yes—the INFINITY DEVELOPER SDK includes ARM64 binaries and POSIX-compliant build scripts for deployment on Ubuntu LTS and Yocto-based industrial controllers.
Are firmware updates field-installable?

Yes. Firmware upgrades are delivered as signed .bin packages via the SDK; update verification includes SHA-256 checksum validation and rollback capability.
