摘要:
The present invention is a lens assembly (10) for an infrared window through which infrared inspection of apparatus within a housing is performed when the lens assembly is mounted in an aperture provided in the housing. The lens assembly comprises an infrared transmitting pane (11) having two generally opposed surfaces (14); and a first protective grille (12) lying against one of said opposed surfaces (14) and having an array of holes (20) formed therethrough that permit infrared inspection of the apparatus through the pane. A second protective grille (12) may be provided on the opposite face and there can be alignment means (21, 32) to ensure correct alignment of each with respect to the other.

摘要:
The invention relates to process for producing a quartz glass optical body which is greatly resistive to irradiation of a laser having a short wavelength. According to the invention a quartz glass body is doped with hydrogen during and/or after production of the quartz glass body to a concentration in the range of 2 x 10 molecules/cm to 5 x 10 molecules/cm . To eliminate reduction-related defects induced by hydrogen in the bulk, the quartz glass body is irradiated with ultraviolet light of a wavelength in the range 150 nm to 300 nm. By such an irradiation hydrogen-induced defects occurring in production of synthetic quartz glass body by means of an oxyhydrogen flame or formed in a high-temperature hydrogen treatment are eliminated and thereby the quartz glass body is greatly improved in a stability against ultraviolet light. A quartz glass optical body according to the invention is especially suitable for use with an ArF eximer laser of 193 nm in wavelength or a YAG fifth harmonics laser of 213 nm in wavelength.
