発明の名称 (英語) Cryostat 実績あり
発明の概要(英語) (US8248596)
A cryostat includes: a casing having an inlet port and exit port; a cell housing provided in the casing; a temperature controller for adjusting the temperature of the cell; a first optical path tube for guiding a light beam from the inlet port of the casing to the cell housing; a second optical path tube for guiding the light beam having passed through the cell housing to the exit port of the casing; first and second optical windows disposed at openings, exposed to the outside, of the first and second optical path tubes, respectively; and sealing materials having a water vapor transmission rate of 30000 cc·cm2·mm·sec·cm Hg×1010 or lower, disposed at the peripheries of the first and second optical windows to seal the first and second optical path tubes.
特許請求の範囲(英語) [claim1]
1. A cryostat comprising: a casing in which an inlet port and an exit port are formed;
a cell housing provided in the casing;
temperature control means for adjusting the temperature of the cell;
a first optical path tube for guiding a light beam entering the inlet port of the casing to the cell housing;
a second optical path tube for guiding the light beam that has passed through the cell housing to the exit port of the casing;
a first optical window and a second optical window that are disposed at openings, exposed to the outside, of the first optical path tube and the second optical path tube, respectively; and
sealing materials that are disposed at the peripheries of the first and second optical windows to seal the first and second optical path tubes and have a water vapor transmission rate of 30000 cc.cm2.mm.sec.cm Hg * 1010 or lower.
[claim2]
2. The cryostat according to claim 1, wherein the largest diameters of the first and second optical windows are each 16 mm or larger.
[claim3]
3. The cryostat according to claim 1, wherein the first and second optical path tubes contain an ethylene fluoride resin.
[claim4]
4. The cryostat according to claim 1, wherein the sealing materials contain a fluorine-containing polymer and/or a butyl rubber.
[claim5]
5. The cryostat according to claim 4, wherein the fluorine-containing polymer is at least one member selected from a binary fluororubber and a ternary fluororubber.
[claim6]
6. The cryostat according to claim 1, further comprising an aperture window for restricting a light beam entering the first optical window.
[claim7]
7. The cryostat according to claim 1, further comprising a gas flow path for feeding a gas to the first optical path tube and/or the second optical path tube.
[claim8]
8. A circular dichroism spectrometer comprising the cryostat according to claim 1.
