Wavelight Technologies, a provider of laser systems and spectral instrumentation solutions, is showcasing its WM series of monochromators and spectrographs designed for spectroscopy, optical analysis, and monochromatic light generation applications. The product family includes the WM100, WM200, WM300, WM400, WM500, and WM600 models, offering users a range of configurations optimized for different measurement and research requirements.

The WM100 is a compact, high-aperture, short-focus monochromator that operates across a spectral range of 190 nm to 1200 nm. When combined with a suitable light source, the instrument can be used as a monochromatic illuminator for fluorescence excitation applications, providing researchers with a flexible source of wavelength-selectable light. For users seeking a multifunctional platform, the WM200 combines monochromator and spectrograph capabilities within a compact form factor. According to the company, the instrument is designed to provide performance characteristics typically associated with larger spectrographs while maintaining a low-cost and space-efficient architecture. Its versatility makes it suitable for a variety of optical measurement and spectroscopy tasks.

The WM300 monochromator is positioned as a high-aperture instrument featuring excellent spectral line quality and low stray-light performance. The system incorporates a 284 mm focal length optical design and provides a 30 x 10 mm flat field, supporting applications that require high-quality spectral imaging and wavelength analysis. Among the more advanced systems in the portfolio is the WM400, a compact double monochromator engineered for enhanced functionality and improved stray-light suppression. A distinguishing feature of the instrument is its ability to operate in both additive and subtractive dispersion modes, allowing users to optimize performance for different experimental and analytical requirements. This dual-mode capability provides additional flexibility for applications requiring precise wavelength selection and spectral filtering.

The WM500 serves as a long-focal-length automated universal monochromator. The system is designed to deliver high spectral line quality while minimizing stray light. It supports up to two input ports and two output ports, allowing flexible optical configurations. The input section can be equipped with either a standard entrance slit or an optional crossed input slot, while all spectral slits are automated with software-controlled width adjustment, enabling precise instrument control and repeatable measurements.

At the top end of the series, the WM600 monochromator is available in a double-dispersive configuration referred to as the Double WM300. In this arrangement, the output slit of the first WM300 functions as the input slit of the second unit, effectively creating a two-stage dispersion system. According to Wavelight Technologies, this configuration provides improved spectral resolution, approximately twice the performance of a single-stage system, while also reducing stray light through increased focal length and additional optical dispersion.

The WM series forms part of Wavelight Technologies’ broader portfolio of spectral instruments, which includes monochromators, spectrometers, tunable light sources, and related optical accessories. By offering solutions ranging from compact monochromators to advanced double-dispersive spectrographs, the company aims to address the needs of researchers, laboratories, and industrial users engaged in spectroscopy, fluorescence studies, optical characterization, and photonics research.
