Abstract
本发明涉及使用积分球的分光光度计的结构。以前,积分球固定在样品室内的底座上,因而,必须根据样品和测量目的来准备各种各样的积分球测量装置。本发明的分光光度计将积分球安装座设置在样品室内的底座上,可以任意改变积分球在样品室内的位置,并且可以使用光入射窗口和光出射窗口的相互位置不同或是窗口数量不同的各种形状的积分球。这样就可以根据测量的目的任意选择利用预先准备的几种积分球,从而进行各种积分球测量。
Description
本发明涉及利用积分球的分光测量装置。
在利用普通积分球的分光测量中,使用分光光度计,并在分光光度计的样品室内设置积分球测量用的附属装置进行测量。也就是说,积分球测量装置是作为分光光度计的附属装置而提供的。但在以往的积分球测量装置中,积分球固定在装置底座上。在将积分球设置在分光光度计的样品室内进行测量的情况下,根据样品的种类和形状以及测量目的,改变积分球在样品室内的位置、积分球上的光入射窗口与光出射窗口的相互位置、窗口的数量等都必须适合测量上的需要,并且往往需要特定的积分球。在以往的积分球测量装置中,由于积分球固定在装置底座上,所以存在如下的问题,即用户必须根据样品和测量目的购置各种不同的积分球测量装置。
本发明可以解决上述问题,即利用一台积分球测量装置可以适应于多种样品、多种目的。
在积分球测量装置中,不使积分球固定,而是可以装卸更焕,以便更换使用形状、方向等都不相同的各种积分球。
由于可以对于积分球测量装置的底座装卸积分球,所以可以按照测量目的等来任意选择更换预先准备的几种积分球,而不需要准备多种积分球测量装置。
附图示出本发明的实施例。在图1中,B为积分球测量装置的底座,在其下面设有定位销P,将该定位销配合在分光光度计样品室的底面上的销孔内,因而底座B可以定位设置在分光光度计的样品室内。积分球安装座T固定在底座B上,该安装座T形成倒置箱形并在其中设置光电倍增管D,在安装座的上面与光电倍增管D的受光面相对的位置上开设光透射窗口A,并在该安装座T上以可装卸更换方式安装各种积分球I。此外,在底座B上还安装有反射镜M,用以将分光光度计的分光部分射出的光束导入积分球内。
积分球I的外形如图2所示,其为中空的立方体形状,从上面看,两个角使底部成凸缘形状以形成倒角,在此凸缘部分上穿过通孔h,并通过该孔用螺钉安装在安装座T上的定位位置上。此外,在积分球下面穿出两个定位销孔C,使之与安装座上的定位销t相配合,从而可以定位。
图3以下各图示出为更换用而准备的各种积分球的几个例子,这些是用于二光束分光光度计的例子。图3为标准的积分球,其设有样品光入射窗口Ws、在球面上与其成直角方向的参考光入射窗口Wr、与上述各窗口分别相对的窗口W1、W2及下面的光出射窗口W0。安装时要使W0与安装座T上的光透射窗口A保持一致。S1为测量反射率的待测样品,R1为此时用的标准样品的白光散射板。若这样安装样品S1、R1,则可测量样品的垂直入射中的散射成分。当测量透明样品的透射率时,用虚线表示的样品S2设置在图示的位置上。R2为此时设置在参考光入射窗口上的标准样品。当测量透射率时,窗口W1、W2被标准白光散射板占满。M为固定在底座B上的反射镜。在该标准型积分球中,当测量反射率时,样品的垂直反射光即镜面反射成分由光入射窗口WS出来而不能测量,只能测量纯散射成分,因此,不适宜用于测量含有两种反射成分的全反射光。
图4为适宜用于上述全反射光测量的积分球,窗口W1、W2少许偏离开样品光和参考光的光轴穿通积分球的点,样品S1、标准样品R1在设置时要少许倾斜于入射的样品光或参考光。
图5的例子为测量任意形状样品(例如,透镜、弯曲透明板或厚透明体斜方向的透射率)的透射率用的积分球。在透射率的测量中,图3的窗口W1、W2实质上是不需要的,即使将这些窗口用标准白光散射板占满,其与积分球内表面的反射特性也不是完全一样的,因此,不能进行高精度的透射率测量,但利用图5的积分球可以进行任意形状样品的透射率的精密测量。
图6示出只有光入射窗口Ws(1个)和光出射窗口Wo的积分球,参考光和样品光穿过横向排列的待测样品S和参考样品R,并从共用的光入射窗口Ws射入。在积分球中,窗口尽量少为好,因此,希望采用这种型式的积分球。图6示出测量液氮温度下的样品透射率的情况,DW为保冷用杜瓦瓶,标准样品R为冷冻成不透明状态的水,呈现白光散射板的性质,待测样品也冷冻成不透明状态。
若根据本发明准备各种形状的积分球,则可用一台积分球测量装置进行多种积分球测量,并可提高积分球测量装置的经济性,与用一种积分球无法进行各种测量的情况相比,可以用较少的劳动进行较高精度的测量。
附图的简单说明如下:
图1为本发明积分球测量装置的一实施例的侧视图,图2为表示同一实施例所准备的各种积分球的外形的顶视图,图3、图4、图5和图6为表示按照本发明分别准备的不同积分球的水平断面及其使用状态的附图。
