ZOLIX Omni-V200 Vacuum Ultraviolet Imaging Spectrometer with 200 mm Focal Length

Overview

The ZOLIX Omni-V200 is a compact, high-performance vacuum ultraviolet (VUV) imaging spectrometer engineered for precise spectral analysis in the 80–300 nm range. It employs an aberration-corrected Seya–Namioka (S-N) optical configuration with a 200 mm focal length concave holographic grating—designed to minimize astigmatism and coma while maintaining high throughput and spatial fidelity across the VUV–UV band. Unlike conventional Czerny–Turner monochromators, the Omni-V200’s integrated imaging design enables simultaneous wavelength calibration and spatial mapping without mechanical scanning, supporting both point-source and extended-source measurements. Its operation under ultra-high vacuum (UHV) conditions—down to ≤1×10⁻⁶ Torr—is essential for minimizing O₂ and H₂O absorption bands that otherwise obscure critical spectral features below 190 nm. This makes the instrument suitable for applications requiring high-fidelity detection of atomic hydrogen Lyman-α (121.6 nm), helium resonance lines (58.4 nm, though edge-limited at 80 nm), and higher-order harmonic generation (HHG) spectra from tabletop laser-driven sources.

Key Features

• Aberration-corrected concave holographic grating (1200 g/mm) optimized for VUV–UV imaging performance
• Fixed 200 mm focal length with 32° incidence angle—enabling compact footprint (<350 mm × 220 mm × 180 mm) and mechanical stability
• Wavelength accuracy and repeatability both specified at ±0.1 nm when calibrated with a 1200 g/mm grating—traceable to NIST-certified emission lines (e.g., He I 58.4 nm, Ne I 73.6 nm, Ar I 104.8 nm)
• Dual-output interface architecture: side-mounted slit port for photomultiplier tube (PMT) coupling and rear-mounted C-mount flange for vacuum-compatible scientific cameras (including back-illuminated CCD/CMOS sensors)
• UHV-compatible stainless-steel body with all-metal seals and bake-out capability up to 120°C—ensuring long-term vacuum integrity and low outgassing rates
• Modular mounting options for integration into synchrotron beamlines, laser laboratories, or plasma diagnostics setups

Sample Compatibility & Compliance

The Omni-V200 accepts both pulsed and continuous light sources, including laser-produced plasmas, discharge lamps (e.g., deuterium, hollow-cathode), HHG sources, and synchrotron bending-magnet radiation. Its VUV transmission path requires source-to-spectrometer coupling via differential-pumping stages or direct UHV interconnection. The instrument complies with ISO 14644-1 Class 5 cleanroom assembly protocols during final integration. While not certified to a specific regulatory standard by default, its mechanical design, material selection (316L SS, oxygen-free copper gaskets), and vacuum documentation support compliance with GLP and GMP-aligned laboratory practices. Full vacuum history logs, leak-test reports (helium mass spectrometry), and grating certification documents are provided with each unit.

Software & Data Management

The spectrometer operates with ZOLIX’s SpectraMaster™ control suite (Windows 10/11 x64), supporting real-time wavelength calibration via internal reference lamps (Hg/Ne optional add-on), motorized slit width adjustment (10–200 µm), and synchronized acquisition with external triggers (TTL, LVDS). All raw spectral data are saved in HDF5 format—including metadata headers compliant with the NeXus standard—enabling traceability, batch processing, and third-party interoperability (e.g., Python h5py, MATLAB, Igor Pro). Audit trails record user actions, parameter changes, and calibration events in accordance with FDA 21 CFR Part 11 requirements when configured with digital signature modules and role-based access controls.

Applications

• High-order harmonic spectroscopy for attosecond science and strong-field ionization studies
• Vacuum ultraviolet radiometry and spectral irradiance calibration of synchrotron beamlines
• Plasma diagnostics in fusion research (e.g., impurity line identification in tokamak edge plasmas)
• Photoelectron spectroscopy pre-filtering and photon energy selection in ARPES systems
• Material reflectance and transmittance characterization of multilayer optics (e.g., Mo/Si, Ru/B₄C) used in EUV lithography development
• Gas-phase reaction dynamics monitored via time-resolved VUV absorption

FAQ

What vacuum pumping configuration is required to achieve ≤1×10⁻⁶ Torr?
A two-stage system is recommended: a turbomolecular pump (≥300 L/s for N₂) backed by a dry scroll pump, with a cold trap or cryopanel optional for hydrocarbon suppression.
Can the Omni-V200 be retrofitted with a different grating groove density?
Yes—ZOLIX offers factory-swappable gratings (600, 1200, or 2400 g/mm) with recalibrated optical alignment and updated firmware maps.
Is the slit width motorized and software-controllable?
Yes—the precision micrometer-driven slit (10–200 µm range) is fully integrated into SpectraMaster™ with position feedback and programmable step resolution of 1 µm.
Does the instrument include a built-in wavelength calibration source?
Not by default; however, a compact Hg/Ne pen-ray lamp module (ZOLIX CAL-UV) can be mounted directly onto the entrance flange as an optional accessory.
What camera interfaces are supported for vacuum-compatible imaging?
Standard C-mount vacuum feedthroughs accommodate Andor iStar, Princeton Instruments PI-MAX, or custom back-thinned CCDs with MgF₂ or LiF windows—ZOLIX provides flange drawings and vacuum compatibility validation reports upon request.
