This invention relates to a source for emitting radiation in the infrared range comprising a thin membrane including a radiation element made from a semi-conductive material having a chosen dopant, the radiation element being connected to a frame, the frame comprising connector means for connecting to a power source for conducting an electrical current through the substrate, the radiation element being provided with a periodic modulation of the refractive index constituting a photonic crystal having a chosen period, thus defining an optical resonator at one or more chosen wavelengths, and wherein the membrane is mounted to the substrate through a number of conductor beams distributed along the membrane circumference so as to provide an even current distribution and thus even heating over the membrane.

Infrared radiation source

The present invention relates to a gas detector cell unit comprising a gas cell, the unit comprising an outer housing providing access to the gas outside through a protecting filter adapted to making gas cell safe for use in explosive environments, i.e. a sintered filter, and the unit comprising means for detecting reduction in the circulation through said protecting filter.

Gas detector clogging detection

The present invention relates to a gas detector cell and cell unit for optical detection of a predetermined gas, the cell being provided with optical means for investigating a gas sample present in the cell. The cell is constituted by a volume enclosed in a container, at least part of the container wall being constituted by a membrane, the membrane being provided with openings allowing diffusion of gas therethrough, and the membrane openings being provided with a catalyst for converting the gas diffusing therethrough to said predetermined gas.

Gas detector

This invention relates to a system and method for detecting target molecules using an optical sensor element including a photonic crystal constituted by a membrane of a chosen transparent material, being provided with a number of defined openings in a chosen pattern, a chosen number of the openings providing capture molecules having a high affinity to target molecules, the pattern being adapted to provide resonance at a chosen wavelength, or range of wavelengths. The system and method also moving a first fluid flow containing target molecules through the openings and after this conducting a second fluid flow containing a second reactant being different from the capture molecules but having a high affinity for the target molecules but a low affinity for other possible molecules in the first flow. By illuminating the sensor element at a chosen wavelength thus obtaining a resonance and imaging means for providing an image of the sensor element it is possible to detect tight leaking from the resonator. Analyzing means may then detect the captured molecules as well as the reactant having reacted with them based on the amount of light leaking from the resonator.

Protein specific optical detection

This invention relates to an optical sensor element comprising a photonic crystal constituted by a membrane of a chosen transparent material, the membrane being provided with a number of defined openings in a chosen pattern, the pattern being adapted to provide resonance at a chosen wavelength or range of wavelengths, wherein said openings are provided with a reactive material acting as a receptor for a chosen type of molecules, e.g. proteins, the presence of which alters the resonance and/or scattering conditions in the sensor element thus altering the amount of light propagating out of the membrane plane.
