技术领域
本发明涉及荧光检测的技术领域,尤其涉及一种多波长荧光检测装置,以及多波长荧光检测方法,能够满足96孔板等微孔式检测通道的对多波长荧光检测需求。
背景技术
荧光分析法是指利用某些物质被特定波长光照射后处于激发态,激发态分子经历一个碰撞及发射的去激发过程能产生反映出该物质特性的荧光,广泛应用于进行定性或定量分析的方法。荧光分析方法具有灵敏度高、选择性好、信号稳定等特点,在荧光PCR仪和96孔板荧光分析仪等生化和环境分析仪器中应用广泛,可对食品和水中化学污染物和致病微生物实现快速检测提供设备和技术保障。
由于荧光试剂具有激发波长较窄的特点,单重试剂难以满足多种物质成分检测的需求,多波长的荧光检测装置受到研究的广泛关注。
发明内容
为克服现有技术的缺陷,本发明要解决的技术问题是提供了一种多波长荧光检测装置,其能够满足96孔板等微孔式检测通道的对多波长荧光检测需求,检测更加准确。
本发明的技术方案是:这种多波长荧光检测装置,其包括:多波长颜色传感器(101)、荧光收集透镜(102)、96孔板(103)、激发光透镜(104)、光纤光源(105)、微孔(106);
光纤光源(105)将多个窄带光谱经激发光透镜(104)照明96孔板(103)上的微孔(106),产生的荧光经荧光收集透镜(102)
收集后照射多波长颜色传感器(101);
荧光收集透镜(102)包括:第一光学透镜(102a)、光阑
(102b)和第二光学透镜(102c),其中光阑(102b)与微孔
(106)中检测液体的中间位置共轭,且与多波长颜色传感器
(101)关于第二光学透镜(102c)共轭。
本发明通过光纤光源将多个窄带光谱经激发光透镜照明96孔板上的微孔,产生的荧光经荧光收集透镜收集后照射多波长颜色传感器,因此能够满足96孔板等微孔式检测通道的对多波长荧光检测需求;荧光收集透镜的光阑与微孔中检测液体的中间位置共轭,且与多波长颜色传感器关于第二光学透镜共轭,能够避免激发光透镜出射的激发光进入多波长颜色传感器,因此检测更加准确。
还提供了多波长荧光检测装置的检测方法,其包括以下步骤:
(1)光纤光源通过时分复用的方式产生多个窄带光谱;
(2)窄带光谱经激发光透镜照明96孔板上的微孔而产生荧光;
(3)产生的荧光经荧光收集透镜收集后照射多波长颜色传感器;
(4)多波长颜色传感器的每个探测器具有一个窄带光谱响应,从而对荧光中的多种物质成分进行检测;
所述步骤(3)中的荧光收集透镜包括:第一光学透镜、光阑和第二光学透镜,其中光阑与微孔中检测液体的中间位置共轭,且与多波长颜色传感器关于第二光学透镜共轭,以便避免激发
光进入多波长颜色传感器。
附图说明

光纤光源105将多个窄带光谱经激发光透镜104照明96孔板103
上的微孔106,产生的荧光经荧光收集透镜102收集后照射多波长颜色传感器101;
荧光收集透镜102包括:第一光学透镜102a、光阑102b和第二光学透镜102c,其中光阑102b与微孔106中检测液体的中间位置共轭,且与多波长颜色传感器101关于第二光学透镜102c共轭。
本发明通过光纤光源将多个窄带光谱经激发光透镜照明96孔板上的微孔,产生的荧光经荧光收集透镜收集后照射多波长颜色传感器,因此能够满足96孔板等微孔式检测通道的对多波长荧光检测需求;荧光收集透镜的光阑与微孔中检测液体的中间位置共轭,且与多波长颜色传感器关于第二光学透镜共轭,由于微孔检测液体的中间位置与照明光纤光源的位置不共轭,可通过调节其位置关系可使诱导荧光与激发光的信噪比最大,因此检测更加准确。
