Patent number: 11022733Abstract: An optical filter having a substrate including a primary bandpass filter at least predominantly on an interference basis and a secondary bandpass filter at least predominantly on an interference basis. Both bandpass filters are designed such that they transmit sufficiently over the entire required angle range in the desired spectral transmittance wavelength interval. The primary bandpass filter contains the small angle shift required by the overall system. It also has a spectral transmittance wavelength interval which is as small as possible according to the requirements of the respective application and restricted by narrow blocking bands. The secondary bandpass filter is designed such that its transmittance wavelength interval is limited by a short-wave edge and a long-wave edge and is adjusted to the primary bandpass filter in such a way that its edges shift over the required angle range only within the blocking bands of the primary bandpass filter.Type: GrantFiled: November 29, 2017Date of Patent: June 1, 2021Assignee: OPTICS BALZERS AGInventor: Thomas Eisenhammer

Publication number: 20080053620Abstract: A first substrate (11a) is positioned on a support surface (7) in a vacuum chamber with an upward-facing first bonding surface (12a) spin-coated with adhesive while a second substrate (11b) is held with downward-facing second bonding surface (12b) to a cover (3) by suction. While the vacuum chamber is being evacuated to a pressure of between 0.1 mbar and 2 mbar, a support pin (9) is extended through central openings (14a, 14b) of the substrates (11a, 11b) and then retracted with the second substrate (11b) released from the cover (3) and carried by radially extended balls (10). The support pin (9) is lowered to a position where the balls (10), acting against the first bonding surface (12a), deform the first substrate (11a). The first bonding surface (12a) being therefore slightly concave, the first and second bonding surfaces (12a, 12b) only touch close to their circumferences.Type: ApplicationFiled: November 2, 2007Publication date: March 6, 2008Applicant: OC Oerlikon Balzers AGInventors: Thomas Eisenhammer, Jeff Ou-Yang

Patent number: 7335521Abstract: A Method for manufacturing an optical disc substrate comprises a first substrate with at least one structured surface, on which an anti-adhesive layer, preferably carbon, is deposited and first layer on top of said anti-adhesive layer. On a second substrate with a structured surface also a layer is deposited. Both substrates are bonded together with the layers facing each other. The separation now easily can take place afterwards alongside the adhesive layer. This way the first layer from the first substrate is being transferred to the second substrate.Type: GrantFiled: June 28, 2005Date of Patent: February 26, 2008Assignee: OC Oerlikon Balzers AGInventors: Martin Dubs, Wolfgang Nutt, Helfried Weinzerl, Thomas Eisenhammer

Publication number: 20050269028Abstract: A method and device for manufacturing a disc-shaped workpiece comprises the steps of producing a first and second disc-shaped substrate, applying an adhesive on at least one of the flat sides of said first and second substrates, bonding said substrates to form said disc-shaped workpiece and removing an excess of adhesive at the outer rim of the disc shaped workpiece by means of a liquid while rotating the workpiece on a rotating table. The liquid is being dispensed by a supply system comprising one or severeal nozzles, used liquid is collected by a suction device.Type: ApplicationFiled: May 13, 2005Publication date: December 8, 2005Inventors: Thomas Eisenhammer, Bernd Heinz, Roger Loow, Cem Yavaser

Patent number: 6860977Abstract: A workpiece is manufactured using a magnetron source that has an optimized yield of sputtered-off material as well as service life of the target. Good distribution values of the layer on the workpiece are obtained that are stable over the entire target service life, and a concave sputter face in a configuration with small target-to-workpiece distance is combined with a magnet system to form the magnetron electron trap in which the outer pole of the magnetron electron trap is stationary and an eccentrically disposed inner pole with a second outer pole part is rotatable about the central source axis.Type: GrantFiled: November 6, 2003Date of Patent: March 1, 2005Assignee: Unaxis Balzers LimitedInventors: Bernd Heinz, Martin Dubs, Thomas Eisenhammer, Pius Grunenfelder, Walter Haag, Stanislav Kadlec, Siegfried Krassnitzer
