Patent number: 8420992Abstract: In microscopes, particularly laser scanning microscopes, for detecting light coming from a sample, it is known to protect detectors from excessively high light outputs by means of shutters in the detection beam path. Further, in order to measure the light output impinging on the detector when the detection beam path is closed, a portion of the light is coupled out of the detection beam path and directed to a monitor diode. Constructions of this kind are complicated and costly. In the microscope according to the invention, a monitor diode is arranged on the shutter in such a way that the monitor diode is situated in the detection beam path when the shutter is closed. This makes it possible in a simple manner to measure the light output in a microscope when the detection beam path is closed even without additionally coupling light out of the detection beam path.Type: GrantFiled: October 15, 2010Date of Patent: April 16, 2013Assignee: Carl Zeiss MicroImaging GmbHInventors: Peter Kuehn, Dietmar Schmidt, Thomas Mehner

Publication number: 20110127406Abstract: An reference light emitted from an LED for auto focus enters a glass cover, on which a sample is adhered to, via a half mirror to an objective lens. The reference light that entered the glass cover is reflected by the boundary surface to be reflected light, and this reflected light enters a dichroic mirror via an objective lens. A part transmits the reflected light and allows the light to enter the camera via the dichroic mirror to the lens. A user rotates a motor-operated mirror while viewing the image of the reference light captured by a camera, so as to shift the reference light image position on the boundary surface.Type: ApplicationFiled: August 29, 2008Publication date: June 2, 2011Applicant: NIKON CORPORATIONInventor: Ichiro Sase

Patent number: 7885528Abstract: A positioning system and method for focusing a charge coupled device (CCD) lens on a selected surface of an object to be measured is provided. The positioning system and method moves the CCD lens downwards to approximate an estimate Z-axis coordinate of the CCD lens, and moves the CCD lens upwards to find an accurate Z-axis coordinate of the CCD lens according to the selected surface of the object. The system and method further moves the CCD lens to a position corresponding to the accurate Z-axis coordinate to focus the CCD lens on the selected surface.Type: GrantFiled: August 14, 2009Date of Patent: February 8, 2011Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Chih-Kuang Chang, Xian-Yi Chen, Li Jiang, Zhong-Kui Yuan, Xiao-Guang Xue

Patent number: 7869706Abstract: A camera head acquires a sample image by shooting a scaled up image of a sample obtained by a microscope body. A memory device records the sample image in a record medium. A CPU detects the completion of the sighting on an observed portion of a sample in a microscope body on the basis of a R. G. B data value of each pixel configuring a microscope image detected by the R. G. B data value. Furthermore, the CPU detects the completion of the focusing on the observed portion by the microscope boundary on the basis of the height of the contrast of the microscope image detected by the focusing completion detection unit. When both completion of the sighting and completion of focusing are detected, the CPU controls a memory device to record a sample image acquired by a camera head on a record medium.Type: GrantFiled: December 4, 2008Date of Patent: January 11, 2011Assignee: Olympus CorporationInventors: Takeshi Minamide, Yujin Arai

Patent number: 7858911Abstract: A semiconductor wafer inspection system and method is provided which uses a multiple element arrangement, such as an offset fly lens array. The preferred embodiment uses a laser to transmit light energy toward a beam expander, which expands the light energy to create an illumination field. An offset fly lens array converts light energy from the illumination field into an offset pattern of illumination spots. A lensing arrangement, including a first lens, a transmitter/reflector, an objective, and a Mag tube imparts light energy onto the specimen and passes the light energy toward a pinhole mask. The pinhole mask is mechanically aligned with the offset fly lens array. Light energy passing through each pinhole in the pinhole mask is directed toward a relay lens, which guides light energy onto a sensor. The offset fly lens array corresponds to the pinhole mask.Type: GrantFiled: July 11, 2008Date of Patent: December 28, 2010Assignee: KLA-Tencor CorporationInventors: Christopher R.

Publication number: 20100308205Abstract: A method for auto focus searching of optical microscopes is revealed. At first, sample a plurality of image signals according to a plurality of sampling positions. Then process the plurality of image signals to get a plurality of energy values. Next calculate a plurality of sharpness values of adjacent energy values and also calculate an absolute value corresponding to the sharpness value. Later check and find out a maximum value of the absolute values to get a sampling position corresponding to the image with the maximum value and use that position as the optimal focus position of the optical microscopes. By the sampling way, the energy values of the image signals are captured so as to save calculation time. Moreover, a sharpness value of adjacent energy value is also calculated so as to check the image captured at the best focus position quickly and reduce focus searching time of the optical microscope. Therefore, the focusing efficiency of the optical microscope is improved.Type: ApplicationFiled: September 21, 2009Publication date: December 9, 2010Applicant: CHUNG YUAN CHRISTIAN UNIVERSITYInventors: MING CHANG, CHIH-TAO TSENG, HSU-HUNG WEI

The tilt angle adjusting mechanism is equipped with the at least two optical inspecting apparatuses so as to adjust the tilt angles of the at least two optical inspecting apparatuses. When the tilt angles of the optical inspecting apparatuses are changed, the focuses of the optical inspecting apparatuses remain at a single position and a subject to be inspected is within the fields of view of the optical inspecting apparatuses. The three-dimensional profile of the subject can be obtained by building the images collected by the two optical inspecting apparatuses.Type: GrantFiled: May 2, 2012Date of Patent: January 15, 2013Assignee: Industrial Technology Research InstituteInventors: Wei Cheng Wang, Shih Hsuan Kuo, Jin Liang Chen
