Publication number: 20120134026Abstract: An acid and alkali resistant coating for an optical lens comprises: a silicon dioxide layer 1, an antireflection film layer 3, hardening layer 5 applied upon a lens blank 6. Optionally, nickel-chromium alloy layers 2 and 4 are added between the silicon dioxide layer 1 and antireflection film layer 3, between antireflection film layer 3 and hardening layer 5. A layer of nickel-chromium alloy may be added before vacuum coating the antireflection film layer. The layer of nickel-chromium alloy is added so that a hardening layer will be protected and to improve the connection or adhesion of the hardening layer and the antireflection film layer. In addition, a layer of nickel-chromium alloy may also added between the antireflection film layer and waterproof layer. The end product comprises protective antireflection or antiglare film improving acid and alkali resistance.Type: ApplicationFiled: November 30, 2011Publication date: May 31, 2012Inventors: Zhao Zhigang, Cai Xiangyou

Patent number: 8183033Abstract: The invention relates to methods for preparing and performing quantitative PCR analyses, a new sealing device and a new use. According to the invention, a sample vessel containing the samples to be analyzed is sealed by placing a planar sealing device on the vessel to cover the samples and applying pressure on the sealing device in order to deform the sealing device so as to form a light-refracting geometry individually for the samples to be analyzed. The invention offers a convenient way of sealing the vessel and forming analysis-improving optical lenses over the samples simultaneously.Type: GrantFiled: March 21, 2008Date of Patent: May 22, 2012Assignee: Bioinnovations OyInventor: Bruce R Turner
