    • PROBLEM TO BE SOLVED: To provide a method and an apparatus for quantitatively measuring (determining) the optical quality of a transparent material. SOLUTION: A scatter volume is formed in a sample by emitting a light beam into the sample consisting of the transparent material. The light is scattered in the scatter volume at a predetermined scatter angle (Θs), and imaged on a light-sensitive element. A signal from the light-sensitive element is integrated or accumulated over a part of the scatter volume. A measurement value is measured and indicates the optical quality of the sample consisting of the transparent material. A measurement variable is measured by using only an engagement of a signal not generated from a scatter of the incident light beam on a light entrance face or a light exit face of the sample.

    • 要解决的问题:提供一种用于定量测量(确定)透明材料的光学质量的方法和装置。 解决方案:通过将光束发射到由透明材料组成的样品中,在样品中形成散射体积。 光在散射体积中以预定的散射角(θs)散射,并在光敏元件上成像。 来自光敏元件的信号在散射体积的一部分上被积分或累积。 测量测量值,并指示由透明材料组成的样品的光学质量。 通过仅使用从入射光束的散射不产生的信号与样品的光入射面或光出射面的接合来测量测量变量。 版权所有(C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a method of surely and easily cutting off a bent substrate from a brittle material. SOLUTION: The method of cutting off the bent substrate from the brittle material includes following processes: a process for arranging the curved substrate on a supporting body; a process for directing laser beam having orientation vertical to the supporting body toward a separation line; a process for moving the laser beam accompanied by a following cooling spot along the separation line with 2 steps composed of a 1st step for adjusting process parameters such as the laser output, a laser beam profile, the focus position of the laser beam profile, the proceeding rate, and cooling to notch the substrate up to a prescribed depth along the separation line and a 2nd step for properly increasing mechanical stress corresponding to the parameters to make the notch formed in the 1st process more deep to completely separate the substrate off; and a process for removing the separated processing member.

    • PROBLEM TO BE SOLVED: To drastically improve the stress birefringence of a crystal, to make the refractive index highly homogeneous over the whole volume of the crystal, and to provide the crystal especially as a crystal used for an optical element.
      SOLUTION: The method for producing a low stress, large volume crystal having prescribed dimensions confined in diameter and height, low stress birefringence and a homogeneous refractive index is constituted of (a) a process for growing a crystal having dimensions larger than prescribed dimensions from a melt, (b) a process for cooling the crystal having the large dimensions obtained in the process (a), (c) a process for tempering the crystal having the large dimensions obtained in the process (a), and (d) a process for removing the edge parts of the crystal so that the crystal has the prescribed dimensions confined in diameter and height by cutting each of the diameter and the height of the crystal by at least 5% after cooling in the process (b) and tempering in the process (c). In this method, tempering of the crystal is not performed after removing the edge parts.
