Description

本発明は低圧水銀ランプ等から放射される紫外線量を測定するために使用する紫外線強度計の改良に関する。   The present invention relates to an improvement in an ultraviolet intensity meter used for measuring the amount of ultraviolet rays emitted from a low-pressure mercury lamp or the like.

従来、波長の異なる二つ以上の光を放射する例えば低圧水銀ランプからの放射光を測定する場合、複数の紫外線強度計を用意し、各波長に対応するセンサを有する紫外線強度計選択して単独に測定することが実施されている。低圧水銀ランプは185nmと254nmの波長の光を放射する。   Conventionally, when measuring light emitted from, for example, a low-pressure mercury lamp that emits two or more lights having different wavelengths, a plurality of ultraviolet intensity meters are prepared, and an ultraviolet intensity meter having a sensor corresponding to each wavelength is selected and used alone. Measurements have been carried out. The low-pressure mercury lamp emits light with wavelengths of 185 nm and 254 nm.

また近年多用されてきているキセノンエキシマランプは172nmの波長の光を放射する。   In addition, xenon excimer lamps that have been widely used in recent years emit light having a wavelength of 172 nm.
