Abstract: A white-light interferometric measuring device includes: a white light source that emits a white light beam; a beam splitter that reflects the white light beam; and an interference objective lens that collects the white light beam having reflected off the beam splitter in the direction of an optical axis and irradiates a measurement workpiece with the white light beam, the interference objective lens generating interference between a measurement light beam obtained by reflection of the white light beam off the measurement workpiece and a reference light beam obtained by branching of the white light beam to be converged on the measurement workpiece. Polarization correcting means that corrects the white light beam to enter the interference objective lens to circularly polarized light is arranged between the white light source and the interference objective lens.

Abstract: A lens system includes a tubular vibrating member that vibrates due to an input drive signal; a case accommodating the vibrating member; a fluid that fills the case and immerses the vibrating member; and a pressure mitigating member that is installed in a gap between the vibrating member and the case, further outward than the vibrating member. A foam body made of fluororubber and having a large number of closed cells is used as the pressure mitigating member.

Abstract: An autofocus apparatus according to an embodiment of the present invention is provided with an image acquirer, a pattern controller, and a focus controller. The image acquirer includes an optical system which forms an image of an object at a predetermined magnification and an image capturer which photographs the image of the object formed by the optical system. The pattern controller includes a generator which generates a pattern in a size according to the predetermined magnification of the optical system and a projector which projects the pattern generated by the generator onto the object. In the focus controller, an image of the projected pattern formed by the optical system at the predetermined magnification controls a focus position of the optical system based on the image of the object photographed by the image capturer.

Abstract: An interference measuring device comprises: a light source; a beam splitter that causes the light to diverge into a reference optical path and a measurement optical path and that outputs a combined wave in which reflection light passed the reference optical path and reflection light passed the measurement optical path are combined; a reference light diverging part that causes the light diverged into the reference optical path, to further diverge into a plurality of optical paths and that causes reflection light beams respectively passed the optical paths to be input into the beam splitter; and a plurality of reference mirrors that are respectively arranged in the optical paths such that optical path lengths of the optical paths are different from each other, and that reflect reference light. An interference image is imaged by varying the optical path length of either the reference optical path or the measurement optical path.
