VUV/UV Spectrometers Monochromators

Resonance 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.

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.

Remote Sensors

Remote Sensors

Resonance 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.

Detectors and

Fiber Optics

Resonance provides detection systems that have sensitivity ranges from the soft X-Ray to the Far IR. Amplifiers and signal processing amplifier, D to A converters, computer interfaces and software are provided with suitable software development kits. Also Resonance will build fiber optic and hollow core interfaces to transmit light from 110 to >10,000 nm.
