摘要： An optical resonator fabricated from a uniaxial birefringent crystal, such as beta barium borate. The crystal is cut with the optical axis not perpendicular to a face of the cut crystal. In some cases the optical axis lies in the plane of the cut crystal face. An incident (input) electromagnetic signal (which can range from the infrared through the visible to the ultraviolet) is applied to the resonator. An output signal is recovered which has a frequency that is an integer multiple of the frequency of the input signal. In some cases a prism is used to evanescently couple the input and the output signals to the resonator.

摘要： A multiple wavelength total internal reflection fluoresence (TIRF) microscopy system has an objective. A dispersion unit of the system comprises a high-dispersion optical element. The dispersion unit receives illumination light having at least a first wavelength λ1 and a second wavelength λ2, where λ1≠λ2, and splits the illumination light into a first monochromatic beam having the first wavelength λ1 and a second monochromatic beam having the second wavelength λ2. The monochromatic beams are focused onto a back focal plane of the objective, near an outer edge of the objective, at different radial distances from an optical axis of the objective. The dispersion unit is rotatable in order to adjust angles of incidence of the monochromatic beams onto an interface between a substrate and a sample to be imaged, wherein the angles of incidence are greater than the critical angle of the interface.

摘要： A device for the evanescent illumination of a sample, including an optical illumination element with an optical corrective element and an objective arranged downstream from the corrective element, to evanescently illuminate the sample with a supplied ray beam containing optical radiation with at least two different wavelengths. The corrective optical element has a transverse chromatic aberration which, during the illumination, leads to the optical radiation penetrating the pupil of the objective at different heights relative to the optical axis varying according to the wavelength. The corrective optical element is selected in such a way that the wavelength-related difference of the penetration depths of the radiation into the sample is reduced during the evanescent illumination.
