    摘要： A particle characterisation apparatus is disclosed comprising: a light source; a sample cell; a collecting lens and a detector. The light source is operable to illuminate a sample comprising dispersed particles within the sample cell with a light beam along a light beam axis. The light beam axis passes through a first wall of the sample cell, through the sample, and through a second wall of the sample cell, so as to produce scattered light by interactions with the sample. The detector is configured to detect light scattered from the sample. The second wall of the sample cell comprises a lens with a convex external surface through which the light beam axis passes. The collecting lens is arranged to collect and focus scattered light leaving the sample cell onto the detector, and comprises an aspheric surface.

    摘要： A lighting apparatus including a body (410), a light source unit (310; 420) disposed on the body to generate light, and a lens (320; 440) disposed on the body to refract light generated from the light source unit. The lens includes a light introduction surface (322; 442) for introduction of light; and a light emission surface (324; 446) for passage of light having passed through the light introduction surface, wherein a ratio of a first distance (RF1; RF1') to a second distance (RB1; RB1') with respect to the light introduction surface is less than 1 and a ratio of a first distance (RF2; RF2') to a second distance (RB2; RB2') with respect to the light emission surface is greater than 1 to less than 2.2,
    wherein the first distance with respect to the light introduction surface is a distance between a first reference plane (610; 610-1) and a lowermost end (322-2; 442-2) of the light introduction surface located at one side of the first reference plane and the second distance with respect to the light introduction surface is a distance between the first reference plane and the lowermost end of the light introduction surface located at the other side of the first reference plane,
    wherein the first distance with respect to the light emission surface is a distance between the first reference plane and the lowermost end of the light emission surface located at one side of the first reference plane and the second distance with respect to the light emission surface is a distance between the first reference plane and the lowermost end of the light emission surface located at the other side of the first reference plane, and
    wherein the first reference plane passes through a center (401) of the light introduction surface.

    摘要： A light-emitting device (10) includes: a light-emitting element (1); and a light flux controlling member (2) for controlling light emitted from the light-emitting element (1), the light flux controlling member (2) has (i) a light-incoming surface (2a) which the light emitted from the light-emitting element (1) enters and (ii) a light-outgoing surface (2b), and the following equation (1) is satisfied where r is a length, from a light axis Z of the light-emitting device (10), of a plane that is provided at a certain distance from the light flux controlling member (2) in a direction parallel to the light axis Z so as to be perpendicular to the light axis Z, Æ 1 is an angle between the light emitted from the light-emitting element (1) and the light axis, P(Æ 1 ) is a light distribution property of the light-emitting element (1). This provides a light-emitting device that scatters light without generating uneven brightness on a liquid crystal display panel, reduces a reflectance caused by the Fresnel's reflection, and has an improved scattering ability.

    摘要： The invention refers to an optical system comprising at least two optical elements of which at least one is movable relative to the other in a direction perpendicular to the optical axis of the optical system, wherein the combination of optical elements is adapted to correct variable aberrations of at least two different orders simultaneously of which the degree of correction depends on the relative position of the optical elements. This optical system is adapted to correct aberrations which are variable and dependent on the position of the lens with respect to the subject/imaging plane. Further the optical system is adapted to correct aberrations varying along with defocus of the system. These aberrations may include second order aberrations, meaning defocus and astigmatism, third-order aberrations, meaning comas and trefoils, fourth-order aberrations, for example, spherical aberration, and further higher-order aberration terms.
