摘要： An optical slide intended to receive a biological sample for the purposes of total internal reflection microscopy. Such an optical slide includes a glass base substrate and a stack of thin layers of alternating dielectric materials which is arranged on the substrate, the free layer of the stack being biocompatible. The stack has index and layer thickness characteristics for supporting the surface waves at the interface between the free layer and the sample, such that the imaging sensitivity and resolution of total internal reflection microscopy are improved.

摘要： The invention has an object to provide an optical device which can directly and efficiently introduce a planar incident light as it is and can efficiently obtain a planar total reflected light on a desirable interface without using a light guiding plate or an optical waveguide, and is constituted by a reflector having no absorption without depending on an incidence angle. The invention provides a planar optical device characterized by such a feature that when an incident light is introduced like a plane into the optical device, at least apart of the incident light thus introduced is totally reflected by an interface of layers constituting the optical device, while the incident light is not substantially emitted from an opposite side to an incident light introduction side.

摘要： There is provided a lens formed from a circular bottom face (11), lateral face (14) and top face (15) and having a surface light source (13) of a finite size disposed at the center of the bottom face (11). The top face (15) is an aspheric surface rotational symmetric with respect to a z-axis and which totally reflects a part of a component, whose polar angle is smaller than a polar angle Θ0 at the intersection between the lateral face (14) and top face (15), of light emitted from the surface light source (13). The lateral face (14) is an aspheric surface rotational symmetric with respect to the z-axis and pervious to a component, whose polar angle is larger than the polar angle Θ0, and component, totally reflected at the top face (15), of the light emitted from the surface light source (13). A function r=fS(z) where z is a variable representing the lateral face (14) increases monotonously as the variable z decreases in a closed zone defined by 0≦z≦z1 (z-coordinate of an intersection between the lateral face (14) and top face (15)), and has at least one point where a absolute value |d2r/dz2| is maximum in the closed zone.

摘要： Filtering apparatus is provided for isolating a very narrow optical frequency range in the order of a spectral line width. Features include a fixed geometry of a light input member relative to a barrier member as well as an appropriate selection of the media of these two members. The media of the input member can be any material that is more refractive than the barrier member and it has a flush interface with the barrier member disposed at such an angle that the interface angle of incidence is greater than the critical angle of the two members. Thus, all light wavelengths other than the wavelengths of particular concern, are internally reflected in the input member. To permit the desired optical frequency bank to pass, the barrier member is formed of a media having a capacity for absorbing input light in the immediate vicinity of a wavelength that falls within the narrow frequency pass band. The absorption produces an irregularity in the refractive dispersion curve for the barrier media. When the angle of incidence and the interface of the input and in barrier members is fixed sufficiently close to the critical angle for this interface, the irregularity varies the relative refractive index sufficiently to vary the relationship of the critical angle with the angle of incidence and permit the narrow band to pass into the barrier member and on into the output member.

摘要： A dichroic beam separator is described which is capable of efficiently separating a second and/or third harmonic beam from the residual fundamental beam. Because the device consists of a single uncoated piece of high quality optical glass, it has a high threshold for laser-induced optical damage.
