Resonance, a Canadian developer of electro-optical instrumentation, continues to support scientific research, industrial measurement, and advanced spectroscopy applications through its extensive portfolio of vacuum ultraviolet (VUV), ultraviolet (UV), visible, and infrared spectrometers, spectrographs, and monochromators. Drawing on more than three decades of expertise in VUV-to-IR technologies, the company offers a range of modular instruments designed for high-performance spectral analysis and flexible system integration.

At the core of the portfolio are Resonance’s spectrometer and monochromator platforms, which are engineered to operate across a wide spectral range extending from the deep ultraviolet to the near-infrared. The modular architecture allows users to convert many systems between monochromator and spectrograph configurations using standard accessories, increasing versatility while reducing downtime in research and testing environments.

Among the company's compact spectrograph offerings is the VS7550 Mini Spectrograph, a miniature Czerny-Turner design that combines high speed, broad spectral coverage, and strong spectral resolution. The system incorporates software-controlled slit settings, grating angle adjustment, order-sorting filters, and exposure management. A dedicated VUV version includes a UHV window and laminar-flow purge system, enabling operation down to approximately 112 nm.

For vacuum spectroscopy applications, Resonance offers several monochromator and spectrometer platforms, including the VM92, VM200, VM300, VM300CT, and VM600CT. These instruments are designed to couple directly to vacuum chambers through Conflat-style flanges, allowing researchers to observe and analyze processes in controlled vacuum environments. The systems can be configured as manual monochromators, motorized monochromators, or CCD-based spectrometers depending on application requirements.

The VM92 delivers a compact solution for VUV and UV measurements, featuring high-throughput optics, spectral coverage from 55 nm to 600 nm, and a lightweight design suited for laboratory and vacuum-system integration. Its interchangeable accessory architecture enables users to switch between monochromator and spectrometer operation while maintaining high VUV efficiency. Building on this platform, the VM200 provides enhanced resolution and accuracy while preserving a compact footprint. The instrument supports manual or motorized wavelength scanning and can be equipped with CCD detectors, photon-counting accessories, pulse-sensitive detection options, and wavelength-specific detector configurations spanning from soft X-ray to near-infrared regions.

For applications requiring greater spectral resolution, the VM300 and VM300CT models offer longer focal lengths and higher-performance optical configurations. The VM300CT, for example, supports operation across the 115 - 600 nm wavelength range, features interchangeable gratings, adjustable slits, hyperspectral imaging options, and wavelength reproducibility of 0.005 nm. The system can function as either a monochromator or a CCD spectrometer, providing flexibility for demanding analytical and research tasks.

At the high-resolution end of the portfolio, the VM600CT combines a 608 mm focal length with high-dispersion gratings to achieve wavelength resolution as fine as 0.015 nm. The instrument supports both gas-purged and evacuated operation, enabling measurements in spectral regions where atmospheric absorption would otherwise limit performance.

In addition to standalone instruments, Resonance offers a wide range of accessories, including adjustable slit assemblies, CCD detector arrays, motorized wavelength drives, order-sorting filters, vacuum pumping systems, collimators, and software packages for spectrum acquisition and analysis. These components allow users to tailor systems to specific experimental, industrial, or educational requirements. With its combination of compact vacuum-compatible designs, modular architecture, broad spectral coverage, and configurable operation modes, Resonance continues to provide advanced spectroscopy solutions for applications ranging from fundamental scientific research and materials analysis to aerospace, industrial testing, and optical instrumentation development.
