The layer includes an inner area and an outer area. A sufficient number of voids can be created in the inner area to form a first index of refraction. A plurality of the voids have a dimension that is less than a wavelength of the light beam. A sufficient number of voids can be created in the outer area to form a second index of refraction less than the first index.

    摘要： A deformable optical element includes an elastically deformable lens. Electrical contacts are directly attached to the elastically deformable lens and configured to receive an applied voltage. The electrical contacts have opposing surfaces configured to develop electrostatic forces in response to the applied voltage. The electrostatic forces deform the elastically deformable lens to create a predetermined optical effect.

    摘要： Raman spectroscopy systems include an analyte, a radiation source configured to emit incident radiation having a wavelength, and a detector that is capable of detecting only radiation having wavelengths within a detectable range that includes at least one wavelength corresponding to hyper Raman scattered radiation scattered by the analyte. The wavelength of the incident radiation is outside the detectable range. In particular systems, all wavelengths of radiation that are scattered in the direction of the detector impinge on the detector. Raman spectroscopy methods include providing an analyte and irradiating the analyte with incident radiation having a wavelength, providing a detector capable of detecting only wavelengths of radiation within a detectable range that does not include the wavelength of the incident radiation, and detecting Raman scattered radiation scattered by the analyte. A continuous path free of radiation filters may be provided between the analyte and the detector.
