Holoeye PLUTO-2.1-NIRO-023 Pure-Phase Spatial Light Modulator

Overview

The Holoeye PLUTO-2.1-NIRO-023 is a high-resolution, pure-phase spatial light modulator (SLM) engineered for precision wavefront shaping in near-infrared (NIR) optical systems. Based on transmissive liquid crystal on silicon (LCoS) microdisplay technology, it delivers diffraction-limited phase modulation with high fidelity and low intensity cross-talk—critical for applications demanding accurate control of optical phase profiles. The device operates exclusively in phase-only mode, enabling efficient implementation of computer-generated holograms (CGHs), beam steering, adaptive optics correction, and structured illumination without introducing unwanted amplitude modulation artifacts. Its native 1920 × 1080 pixel array, with a uniform 8 µm pixel pitch, supports spatial sampling at the diffraction limit for wavelengths centered around 1064 nm, making it particularly suitable for Nd:YAG laser systems, ultrafast pulse shaping, and quantum optics experiments requiring stable, repeatable phase maps.

Key Features

• True phase-only modulation architecture with negligible amplitude modulation (< 2% intensity variation across full phase range)
• High spatial resolution: 1920 × 1080 active pixels, enabling complex hologram generation with fine angular resolution
• Optimized for near-infrared operation—calibrated and pre-aligned for 1064 nm, with optional factory tuning available for other NIR bands (e.g., 780–1550 nm)
• Thermal plug-and-play compatibility: No system reboot required when connecting or disconnecting; supports hot-swap during active optical alignment
• Dual-interface control: Video signal (HDMI/DisplayPort) delivers real-time 8-bit grayscale phase patterns via GPU-accelerated rendering; USB interface independently adjusts gamma curve and voltage range to match specific wavelength-dependent LC response
• Factory-characterized phase response: Delivered with calibrated phase-voltage lookup tables (LUTs) and software tools for rapid integration into MATLAB, Python (NumPy/SciPy), or LabVIEW environments

Sample Compatibility & Compliance

The PLUTO-2.1-NIRO-023 is designed for integration into cleanroom-compatible, vibration-isolated optical benches and OEM instrumentation platforms. Its sealed LCoS module meets IEC 60825-1:2014 Class 1 laser safety requirements when used with appropriate collimation and beam attenuation. While not certified to ISO 13485 or FDA 21 CFR Part 11 as a standalone medical device, its deterministic phase behavior and traceable calibration support GLP-compliant experimental documentation when deployed in regulated research settings (e.g., photonics R&D labs under ISO/IEC 17025 quality management systems). The device complies with CE marking directives for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU).

Software & Data Management

Holoeye provides the SLM Display Software suite—cross-platform (Windows/macOS/Linux), supporting real-time pattern loading, LUT-based gamma correction, and batch sequence playback. All phase maps are stored as standard 8-bit TIFF or BMP files, ensuring interoperability with third-party simulation tools (e.g., COMSOL Multiphysics, Zemax OpticStudio). For automated workflows, a documented C++/Python API enables direct memory-mapped frame buffer access and synchronized triggering via TTL signals. Audit trails—including timestamped phase map uploads, USB configuration changes, and firmware version logs—are exportable in CSV format, facilitating traceability in validation protocols aligned with ISO 9001 or internal QA procedures.

Applications

• Dynamic holographic optical trapping and manipulation of micro-particles in NIR biological imaging
• Multi-plane fluorescence microscopy (e.g., Bessel beam scanning, light-sheet generation)
• Wavefront correction in closed-loop adaptive optics systems using Shack-Hartmann sensors
• Programmable diffractive optical elements (DOEs) for laser material processing and fiber coupling optimization
• Quantum information experiments requiring high-fidelity spatial mode sorting (e.g., OAM multiplexing)
• Educational platforms for teaching Fourier optics, diffraction theory, and computational imaging principles

FAQ

What is the maximum frame rate for dynamic phase pattern updates?
The native video interface supports up to 60 Hz full-frame updates; higher rates (up to 120 Hz) are achievable with region-of-interest (ROI) addressing or compressed phase map streaming using custom GPU kernels.
Can the PLUTO-2.1-NIRO-023 be used with femtosecond pulses?
Yes—its low group delay dispersion ( 1 J/cm² for 10 ns pulses, scaled per pulse duration) make it compatible with Ti:sapphire and Yb-doped fiber amplifier systems when operated within specified average power limits (< 500 mW incident).

Is factory recalibration available after extended use?
Holoeye offers optional annual calibration services including phase uniformity mapping, temporal stability assessment, and updated LUT generation—traceable to NIST-traceable interferometric reference standards.
