Abstract: An arrangement for increasing resolution of a laser scanning microscope has a simplified adjustment and lower susceptibility to errors. The pupil beam from the laser scanning microscope is coupled into a shortened common path interferometer, to make wavefronts of a pupil image mirrored at at least one axis and wavefronts of an unchanged pupil image interfere. The area of a pupil from the pupil beam is split into two complementary portions P and Q producing two partial beams separately supplied to at least one beam deflection means by total-internal reflection along the common path interferometer. The light of the interferometer branches from transmitted light of the one interferometer branch and reflected light of the other interferometer branch is made to interfere at a partly transmissive beam splitter layer to cause constructive interference C and destructive interference D of the wavefronts from the two different portions P and Q of the pupil.

Abstract: Eyewear lenses for frameless eyewear may include a stiffening member configured to increase the stiffness of the eyewear lens. The stiffening member may be an integral part of the lens and extend along the upper portion of the lens. At least a portion of the stiffening member may extend forward of a corresponding point on the front surface of the lens. The stiffening member may have different dimensions and cross sections, based on, for example, the stiffening enhancement needed and aesthetic considerations. The stiffening member may be designed to improve the moment of inertia of the eyewear lens to a desired value when compared to an otherwise identical lens without a stiffening member. The increased stiffness caused by the stiffening member may also be designed to achieve a target head force on the head of a user when the eyewear lens is integrated into eyewear.
