Publication number: 20100208257Abstract: In the spectroscopy module 1, a light detecting element 4 is provided with a light passing opening 4b through which light made incident into a body portion 2 passes. Therefore, it is possible to prevent deviation of the relative positional relationship between the light passing opening 4b and a light detection portion 4a of the light detecting element 4. Further, an optical element 7, which guides light made incident into the body portion 2, is arranged at the light passing opening 4b. Therefore, light, which is to be made incident into the body portion 2, is not partially blocked at a light incident edge portion of the light passing opening 4b, but light, which is to be made incident into the body portion 2, can be guided securely. Therefore, according to the spectroscopy module 1, it is possible to improve the reliability.Type: ApplicationFiled: June 5, 2008Publication date: August 19, 2010Applicant: Hamamatsu Photonics K.K.Inventors: Katsumi Shibayama, Helmut Teichmann, Tomofumi Suzuki, Dietmar Hiller, Ulrich Starker

Publication number: 20100201980Abstract: In the spectroscopy module 1, a light absorbing layer 6 having a light-passing hole 6a through which light L1 advancing into a spectroscopic portion 3 passes and a light-passing hole 6b through which light L2 advancing into a light detecting portion 4a of a light detecting element 4 passes is integrally formed by patterning. Therefore, it is possible to prevent deviation of the relative positional relationship between the light-passing hole 6a and the light-passing hole 6b. Further, since the occurrence of stray light is suppressed by the light absorbing layer 6 and the stray light is absorbed, the light detecting portion 4a of the light detecting element 4 can be suppressed from being made incident. Therefore, according to the spectroscopy module 1, it is possible to improve the reliability.Type: ApplicationFiled: June 5, 2008Publication date: August 12, 2010Applicant: HAMAMATSU PHTONICS K.K.Inventors: Katsumi Shibayama, Takafumi Yokino, Tomofumi Suzuki, Helmut Teichmann, Dietmar Hiller, Ulrich Starker

Publication number: 20100103412Abstract: Since a spectroscopic module (1) has a plate-shaped body section (2), the spectroscopic module can be reduced in size by reducing the thickness of the body section (2). Moreover, since the body section (2) is plate-shaped, the spectroscopic module (1) can be manufactured, for example, by using a wafer process. More specifically, by providing lens sections (3), diffraction layers (4), reflection layers (6) and light detecting elements (7) in a matrix form on a glass wafer which becomes many body sections (2) and dicing the glass wafer, many spectroscopic modules (1) can be manufactured. This enables easy mass production of spectroscopic modules (1).Type: ApplicationFiled: June 5, 2008Publication date: April 29, 2010Applicant: Hamamatsu Photonics K.K.Inventors: Katsumi Shibayama, Helmut Teichmann, Takafumi Yokino, Tomofumi Suzuki, Dietmar Hiller, Ulrich Starker

Patent number: 7605917Abstract: A spectrometer 1A is made up of: an optical body 10 within which a light separation path is set along which an object light to be separated propagates; a light entry slit 16 through which the object light enters; a diffraction grating 17 for spectrally separating the incident object light; and a photodiode array 18 for detecting the object light separated by the diffraction grating 17. As an optical member for optically interconnecting the optical body 10 and the photodiode array 18, an optical connection member 20 is provided, with its light entry surface 21 for the separated object light in contact with the upper surface 11 of the optical body 10, with its light exit surface 22 in contact with the photodiode array 18, with the light exit surface 22 tilted by a specified angle relative to the light entry surface 21. Thus, the spectrometer capable of bringing about sufficient accuracy of placing optical elements in a simple constitution while bringing down cost is realized.Type: GrantFiled: July 8, 2005Date of Patent: October 20, 2009Assignee: Hamamatsu Photonics K.K.Inventors: Helmut Teichmann, Dietmar Hiller, Ulrich Starker

Publication number: 20090135420Abstract: A spectrometer 1A is constituted with an optical body 10, a glass member 11 formed with a light entry slit 12, and a connecting flange 20. The connecting flange 20 is provided with an opening 21 to which the glass member 11 is positioned and inserted, and with positioning rods 25 provided in positions in front of and behind the opening 21 as positioned relative to the opening 21. Using the positioning rods 25, when the spectrometer 1A is applied to the measuring apparatus, makes it possible to connect the spectrometer 1A and other components of the measuring apparatus through a passive alignment method simply with high accuracy. Thus, a spectrometer capable of favorably achieving optical connection to light to be optically separated and a measuring apparatus using the spectrometer can be realized.Type: ApplicationFiled: September 22, 2005Publication date: May 28, 2009Applicant: HAMAMATSU PHOTONICS K.K.Inventors: Dietmar Hiller, Helmut Teichmann, Ulrich Starker

Furthermore, a carrier capturing portion 60, for capturing carriers generated at a substrate portion near the light entrance portion 13 and removes the captured carriers to the exterior via an electrode 61, is arranged from a layer portion of the epitaxial layer 102 that is positioned between the photodiode array 11 and the light entrance portion 13. A photodetector of a simple arrangement, which, when applied to a spectrometer, enables the positioning precision of components of the spectrometer to be improved, and a spectrometer using this photodetector are thus realized.Type: ApplicationFiled: November 24, 2004Publication date: October 23, 2008Inventors: Mitsuaki Kageyama, Katsumi Shibayama, Seiichiro Mizuno, Helmut Teichmann, Dietmar Hiller, Ulrich Starker
