Title: Air-cooled type very high temperature observatory furnace
Inventor: ICHIHASHI MASAHIKO
IPC: F27B17/00
Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To contrive to make the whole observation of a sample by providing a vent device which passes cooling air along an inner peripheral reflective wall and a light source in a system which divides a furnace chamber into a light source chamber and a heating compartment with a transparent partition quartz board and collectingly enters a beam of light from the light source compartment toward the sample. SOLUTION: Infrared rays emitted from an infrared light source 9 in a light source compartment segmented with a transparent partition quartz board 7, are partially reflected directly while the rest is reflected on an inside reflective surface of a lower semi-oval spheric body 3 and a semi-permeable reflective surface of an upper semi-oval spheric body 4, thereby collecting light and heating the sample. The lower semi-oval spheric body 3 and the infrared ray source 9 are cooled with air heat exchange accompanied by the operation of a vent fan 12. More specifically, the vent fan 12 provided on the bottom of a housing 1 draws the cooling air pulled in from an intake opening 8 of the cooling air into the lower semi-oval spheric body 3, thereby discharging the cooling air by way of the opening 3b.  This construction makes it possible to cool the light source 9 and the reflective wall and prevent damages resultant from high temperature.

Filed: 1998-08-13
Abstract: PROBLEM TO BE SOLVED: To provide a Raman microspectroscope and a Raman microspectrometry capable of implementing measurement accuracy with a wave number resolution of approximately 0.01 cm-1. SOLUTION: Laser light with two wavelengths radiated from a laser light source 1 is divided into excitation laser light 2 and reference laser light 3 by a prism 4. The excitation laser light 2 is irradiated onto a sample 8 after passing through an optical system to generate rear Raman scattering light. The Raman scattering light is reflected by a half mirror 6, introduced to a spectroscope 11, and diverged. The reference laser light 3 is attenuated to intensity in the same degree as that of the Raman scattering light by an attenuating plate 14, introduced to the spectroscope 11, and diverged. The location of the detected spectrum of the Raman scattering light might be deviated from the original location by the drift of the spectroscope, etc., due to changes in room temperature. However, by performing correction on the basis of the location of the detected spectrum of the reference laser light 3, it is possible to determine the location of the detected spectrum of the Raman scattering light.
