Patent number: 7405819Abstract: A sample substrate adapted for use with fluorescence excitation light with a first wavelength. A reflector is disposed on a base. The reflector includes a reflecting multilayer interference coating with at least two layers. Not all of the layers L fulfill a quarterwave condition: dL·nL=(2N+1)·¼ wherein dL is a physical thickness of layer L, nL is an index of refraction of layer L at the first wavelength, N is an integer equal to or greater than zero and 1 is the first wavelength. Thicknesses of the layers ensure that any fluorescent sample material disposed on top of said multilayer interference coating would be located near an antinode of a standing wave formed by the excitation light with the first wavelength incident on said substrate.Type: GrantFiled: April 25, 2007Date of Patent: July 29, 2008Assignee: OC Oerlikon Balzers AGInventors: Jorg Kraus, Johannes Edlinger, Max Wiki, Heidi Thome-Forster, Claus Heine-Kempkens, Bernd Maisenhoelder, Martin Kaspar

Patent number: 7215850Abstract: A waveguide plate and a process for making the waveguide plate with a plate-like glass substrate (1), carrying a waveguiding layer (2), with at least one coupling grating on the surface carrying said waveguiding layer (2), which coupling grating is formed as a grating of lines with a period between 150 nm and 1000 nm, the extension of said grating being at least 5 cm with lines parallel to one another, wherein the coupling angle (?) varies by not more than 0.1°/cm along a line of said grating and wherein the absolute value of the deviation of the coupling angle (?) on said waveguide plate, from a predefined desired value, does not exceed 0.5°. The deviation from the average value of the coupling angle does not exceed 0.3°, preferably not 0.15° on the whole waveguide plate.Type: GrantFiled: August 23, 2005Date of Patent: May 8, 2007Assignees: OC Oerlikon Balzers AG, Zeptosens AGInventors: Bernd Maisenhoelder, Johannes Edlinger, Claus Heine, Michael Pawlak, Gert Duveneck

Patent number: 6510263Abstract: A waveguide plate comprising a glass substrate (10) covered with a waveguide layer (2) has coupling grating strips following one another a distance apart, in which the coupling angle changes along parallel lines by not more than 0.1°/cm, preferably not more than 0.05°/cm. The deviation from its mean value over the total waveguide plate is not more than 0.3°, preferably not more than 0.15°. The waveguide plate is suitable as part of a microtiter plate for chemical analyses by means of fluorescence excitation. For its production, the glass substrate (1) is covered with a photoresist layer (10) and exposed to a mercury vapour lamp via a deflecting mirror through a phase mask in the vicinity of which it is arranged, for example at the Littrow angle (&thgr;L) or at a right angle, then structured by reactive ion etching and provided with the waveguide layer (2) by reactive DC magnetron sputtering, in particular pulsed DC sputtering or AC-superposed DC sputtering.Type: GrantFiled: February 3, 2000Date of Patent: January 21, 2003Assignee: Unaxis Balzers AktiengesellschaftInventors: Bernd Maisenhölder, Johannes Edlinger, Clause Heine
