Light Sources

Resonance makes stock and custom light sources from the soft-X ray to the IR region. Resonance's VUV light sources have calibrated instruments on the Hubble Space Telescope and measured atomic species at orbital altitudes. Thousands of Resonance's VUV photoionization bulbs are used for first alert gas sensors around the world. Resonance Visible and NIR light sources have calibrated satellite remote sensors. Resonance line sources have provided intensity and wavelength standards for instruments throughout the world.

More Light Sources



Resonance Ltd. offers both monochromators that select a narrow band of wavelengths and spectrographs which separate light into a frequency spectrum and record it with a camera. All Resonance spectrometers can operate from the Deep UV to the Near IR. Conversion from monochromator to spectrograph is possible with standard accessories.

Remote Sensors

Resonance Ltd. offers optical sensors that can determine gas composition of the atmosphere or plumes from distances of a few meters to hundreds of kilometers. Our Gas Cameras measure gas fluxes from volcanoes and stacks. Our DOAS systems have been used on many volcanoes. Our non-dispersive IR sensors have produced profiles of atmospheric gases from airborne platforms.

Integrated Systems

Systems with seamless integration between light source, test chamber, spectrometer, detector and software. Applications from Raman spectroscopy to automated reflectance, transmittance and fluorescence measurements.

Photo-Ionization Detection (PID) Lamps

Resonance mass produces an extensive range of RF excited lamps filled with a variety of gases. In these lamps, the natural "RESONANCE" frequency of the gas is excited by plasma in the bulb. Combinations of the appropriate fill gases and window materials are used to select near monochromatic energies in the 10.6 to 8.4 eV range.

Calibration Cells

Resonance Ltd. supplies a line of DOAS calibration cells filled with a variety of gases. These cells can be filled to concentrations ranging from 0 -2000 ppm-m and are designed to fit most standard DOAS systems. Made with quartz or Pyrex, these cells can withstand the harshest environments and are extremely resistant to scratches and contamination, providing a long and reliable lifetime

We design and manufacture VUV/UV spectrometers & spectrographs, monochromators, VUV/UV light sources and systems, remote sensors for gas detection and related products.  With over 30 years of specializing in VUV to IR applications, Resonance Ltd. has built up a complete line of high-end products and systems to address almost any need.  Our modular designs allow for fast and easy swapping between components, greatly increasing the versatility of our products while reducing down-time.
