Auniontech TAGLENS Ultra-High-Speed Electrically Tunable Lens

Overview

The Auniontech TAGLENS-T1 is an electrically tunable lens engineered for ultra-high-speed, non-mechanical focus variation across an exceptionally wide focal range. Unlike conventional zoom or autofocus systems relying on motorized lens translation, TAGLENS operates on the principle of ultrasonic modulation of refractive index distribution within a liquid crystal or electro-optic medium—enabling sub-millisecond focal length switching without physical displacement. This solid-state architecture eliminates inertia, backlash, and wear associated with mechanical actuators, making it ideal for applications demanding synchronized optical sectioning, real-time volumetric imaging, and high-repetition-rate inspection in industrial machine vision and scientific microscopy. The lens is designed to integrate seamlessly into OEM inspection platforms, time-resolved imaging setups, and 3D metrology systems where Z-axis scanning traditionally requires precision stages or piezoelectric actuators.

Key Features

• Non-mechanical focus tuning: Achieves continuous focal length variation via voltage-controlled refractive index modulation—no moving parts, no hysteresis, no maintenance.
• Extended depth of field (EDOF) mode: Simultaneously renders sharp imagery across a user-defined axial range, eliminating the need for vertical stage motion during acquisition.
• Multi-focus acquisition: Captures up to 20 discrete focal planes within a single exposure cycle; each plane independently addressable with microsecond-level timing resolution.
• Real-time 3D reconstruction: Enables TAGLENS-3D functionality—generating topographic maps from sequential or interleaved focal plane data without Z-stage translation.
• Fusion imaging modes: Supports mixed-image output (up to three focal planes per frame) and focus-stacked all-in-focus composites using embedded firmware logic.
• OEM-ready interface: Equipped with TTL/RS-422 digital control input and analog voltage modulation support; compatible with standard machine vision frame grabbers and PLC-triggered workflows.

Sample Compatibility & Compliance

TAGLENS-T1 is optimized for integration with standard C-mount or F-mount imaging sensors (up to 2/3” format), and supports optional coupling to inverted or upright microscope bodies via dedicated adapter kits. It maintains diffraction-limited performance across its operational wavelength range (400–1100 nm) and exhibits minimal wavefront distortion (< λ/8 RMS at 633 nm). The lens complies with IEC 61000-6-3 (EMC emission standards) and meets RoHS 2015/863/EU material restrictions. While not certified for medical device use under FDA 21 CFR Part 820, its deterministic optical response and traceable calibration protocol support GLP-aligned documentation for R&D and industrial QA environments. All controller firmware logs timestamped actuation events, enabling audit-ready operation records when integrated with compliant data acquisition software.

Software & Data Management

The included TAGPAK-C control software provides GUI-based focal plane sequencing, waveform generation (sine, sawtooth, arbitrary), and synchronization pulse configuration for external triggers (e.g., laser pulses, motion encoders). APIs are available for Python, MATLAB, and LabVIEW, supporting custom automation of multi-plane capture, z-stack acquisition, and closed-loop focus tracking. Raw image streams retain native metadata—including focal position index, timestamp, and actuation voltage—ensuring full traceability. When deployed in regulated environments, TAGPAK-C can be configured to enforce role-based access control and generate electronic audit trails compliant with ISO/IEC 17025 requirements for measurement uncertainty documentation.

Applications

• High-speed industrial inspection: Eliminates autofocus latency in PCB, semiconductor wafer, and MEMS component inspection—enabling full-field clarity at ×50 magnification without Z-stage dwell time.
• Destructive testing imaging: Captures volumetric detail during impact or explosion events; all fragments remain in focus across depth due to simultaneous multi-plane exposure.
• Microfluidic particle tracking: Resolves 3D trajectories of suspended microparticles (0.5–50 µm) in laminar flow channels by correlating focal plane position with spatial coordinates.
• Robot-mounted vision systems: Reduces robotic path planning complexity—fixed-focus camera + TAGLENS replaces multi-axis positioning for multi-angle surface profiling.
• Confocal-lite microscopy: Provides axial sectioning capability without pinhole scanning or objective translation, suitable for live-cell observation where phototoxicity must be minimized.

FAQ

Does TAGLENS require recalibration after extended operation?

No—its electro-optic response is inherently stable over temperature (±0.5°C) and time; factory calibration remains valid for ≥2 years under typical lab conditions.

Can TAGLENS-T1 be used with telecentric illumination?

Yes—when paired with collimated LED or laser illumination, it preserves telecentricity across its focal range, critical for metrology-grade edge detection.

Is synchronization with pulsed lasers supported?

Yes—TTL-compatible trigger input accepts external sync signals with ≤10 ns jitter, enabling precise gating for time-resolved fluorescence or SHG imaging.

What is the maximum usable numerical aperture (NA) when coupled to a 5× objective?

The effective NA remains constrained by the objective’s front lens; TAGLENS introduces no additional aberration beyond ±0.003 wavefront error (RMS), preserving system-level NA fidelity.

Are optical coatings customizable for specific spectral bands?

Yes—anti-reflection coatings optimized for UV (250–400 nm), VIS-NIR (400–1100 nm), or SWIR (1100–1700 nm) are available as factory options upon request.
