Holoeye PLUTO-2.1-TELCO-013 Pure-Phase Spatial Light Modulator

Overview

The Holoeye PLUTO-2.1-TELCO-013 is a high-resolution, pure-phase spatial light modulator (SLM) engineered for precision wavefront control in near-infrared (NIR) spectral regimes. Based on liquid-crystal-on-silicon (LCoS) microdisplay architecture, it operates as a programmable diffractive optical element—enabling dynamic phase modulation without amplitude coupling—critical for applications demanding high diffraction efficiency and low zero-order leakage. Unlike intensity-based modulators, the PLUTO-2.1-TELCO-013 implements pixelated voltage-controlled birefringence to impose spatially varying phase delays across a 1920 × 1080 active array with 8 µm pitch. Its design targets the 1400–1700 nm band, making it particularly suited for telecom-band coherent optics, fiber laser beam shaping, quantum optics experiments involving erbium-doped or thulium-doped sources, and hyperspectral illumination systems requiring wavelength-specific phase calibration.

Key Features

• Pure-phase modulation architecture with >95% diffraction efficiency in first order under optimized conditions
• Native 1920 × 1080 resolution with uniform pixel pitch (8 µm), supporting sub-microradian beam steering and high-fidelity hologram generation
• Hot-pluggable operation via standard DisplayPort or HDMI video interface—no system reboot required for SLM insertion or removal
• USB-controlled gamma calibration unit enabling real-time adjustment of voltage-to-gray-level mapping for precise phase-depth optimization at target wavelengths
• Support for 8-bit grayscale addressing via green-channel video signal, compatible with off-the-shelf graphics cards and common image viewers
• Thermally stabilized LCoS backplane ensuring phase stability over extended operation (>4 hours at ambient 22°C)
• Integrated driver electronics with low-latency USB 2.0 interface for synchronization-critical applications (e.g., closed-loop adaptive optics)

Sample Compatibility & Compliance

The PLUTO-2.1-TELCO-013 is designed for integration into OEM optical platforms and laboratory-grade instrumentation where traceable calibration and long-term repeatability are essential. It complies with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity requirements) for industrial environments. While not certified for medical or aerospace use out-of-box, its mechanical housing and electrical interfaces meet RoHS 2011/65/EU directives. For GxP-aligned workflows—including those governed by ISO/IEC 17025 or FDA 21 CFR Part 11—the device supports audit-trail-capable software logging when used with Holoeye’s proprietary SLM Control Suite v4.x or third-party LabVIEW/Vision-compatible drivers. Calibration reports (including phase uniformity maps and wavelength-dependent retardance curves) are provided per unit upon request and may be incorporated into laboratory quality documentation.

Software & Data Management

Holoeye provides native support for Windows 10/11 (64-bit) through its SLM Control Suite, which includes phase pattern synthesis tools, gamma curve editor, and real-time phase error compensation algorithms. The suite exports phase masks in standard formats (BMP, TIFF, RAW) and supports scripting via Python API (pySLM) for automated experiment sequencing. All phase data is stored with embedded metadata—including timestamp, applied gamma profile, and system temperature—ensuring full traceability. When deployed in regulated environments, the software can be configured to enforce user role permissions, electronic signatures, and change history logs compliant with ALCOA+ principles. Integration with MATLAB, Python (NumPy/SciPy), and Zemax OpticStudio is validated and documented in the Application Notes Library (v.2024.2).

Applications

• Dynamic holographic projection in NIR hyperspectral imaging systems, where pixel-level phase control enables tunable spectral filtering and multi-angle illumination
• Adaptive optics correction in free-space optical communications (FSOC) operating at 1550 nm and 1625 nm bands
• Beam shaping and mode conversion of ultrafast fiber lasers (e.g., Yb- or Tm-doped oscillators) for micromachining and nonlinear frequency conversion
• Optical trapping and manipulation of dielectric nanoparticles in aqueous media using structured NIR light fields
• Calibration reference for interferometric metrology systems requiring programmable reference wavefronts in the SWIR band
• Education and research in computational optics, including Fourier optics labs and digital holography coursework

FAQ

Is the PLUTO-2.1-TELCO-013 suitable for pulsed laser applications?

Yes—its LCoS response time (<25 ms for full 0–2π phase swing) supports Q-switched and mode-locked lasers with repetition rates up to 10 kHz, provided average power density remains below 1 W/cm² at the active surface.
Can phase patterns be updated synchronously with external triggers?

Yes—the USB interface supports hardware trigger input (TTL-compatible) for frame-locked updates with jitter <100 µs; external sync is also achievable via Genlock-capable graphics cards.
Does the device require periodic recalibration?

No routine recalibration is needed under stable thermal conditions; however, gamma recalibration is recommended after wavelength changes or if ambient temperature shifts exceed ±3°C from initial setup.
What is the maximum usable optical aperture?

The clear active area measures 15.36 mm × 8.64 mm, matching the TFOV specification; vignetting begins beyond this region due to internal relay optics.
Is custom firmware available for OEM integration?

Holoeye offers OEM firmware variants with simplified command sets and deterministic latency profiles under NDA; contact technical sales for qualification and lead-time assessment.
