Patent number: 8380456Abstract: To provide a calibration jig which can perform three-dimensional calibration of measurement errors in a spectacle frame shape measuring apparatus. The calibration jig is used for calibrating measurement errors of the spectacle frame shape measuring apparatus for measuring a shape of a spectacle frame, etc. A trace groove traced by a measuring probe of the spectacle frame shape measuring apparatus is a frame groove formed in an inner circumference of rims of the spectacle frame and provided for engaging with the bevel of a spectacle lens. The rims are secured to a frame body having rigidity higher than that of the rim. The frame groove has a displacement r in the radial direction, a displacement ? in the rotational direction, and a displacement z in the height direction.Type: GrantFiled: February 28, 2007Date of Patent: February 19, 2013Assignee: Hoya CorporationInventors: Takashi Igarashi, Masahiro Jinbo, Ryousuke Satoh

Patent number: 8028650Abstract: A light irradiation device (151) includes a UV lamp (153), first and second optical filters (164, 165) which transmit and block wavelengths within different specific ranges, and a filter switching mechanism (162) which selectively interposes the first and second optical filters (164, 165) between the UV lamp (153) and an optical lens. The blocking wavelength of the first optical filter (164) is relatively longer than that of the second optical filter (165). The first optical filter (164) is interposed between the UV lamp (153) and the optical lens since the start of curing a coating solution until a lapse of a predetermined period of time. When the predetermined period of time has elapsed, the second optical filter (165) is interposed between the UV lamp (153) and the optical lens to replace the first optical filter (164).Type: GrantFiled: March 4, 2005Date of Patent: October 4, 2011Assignee: Hoya CorporationInventors: Masahiro Jinbo, Hiroshi Ota, Takeshi Imizu

Patent number: 7441895Abstract: Aims to enable to supply an optimal and dedicated spectacle lens or spectacle for each spectacle wearer, and also to verify a spectacle wearing state appropriately. A spectacle wearing parameter measurement system, sets a spectacle wearer to be in a distance vision state or a near vision state in which, in the near vision state, at least, one of an eyeball rotation angle and a near vision target distance is changeable optionally; takes an image of the spectacle wearer set in the distance vision state or near vision state by an image pickup device; imports the image; and measures and calculates a spectacle wearing parameter based on the image.
