Monochromator for microplate readers

Abstract

一种光学比色分析领域的用于酶标仪的单色器,包括:若干单色光组件和光导纤维部件,光导纤维部件将各个单色光组件产生的单色光通过各自不同的光路分别聚焦于对应酶标仪的比色杯,并由光电池将光信号转换为电信号。光导纤维部件包括:多通道光纤束以及光学聚焦机构,多通道光纤束的输入端接收若干个单色光组件输出的单色光,光学聚焦机构位于多通道光纤束的输出端并将聚焦至该路对应的比色杯的中心。本发明能够随时获得任意输入波长且能量分布均匀的二至十二束单色光,响应时间短且无需机械运动机构。
The invention relates to the field of optical colorimetric analysis, in particular to a monochromator for microplate readers. The monochromator comprises a plurality of monochromatic light assemblies and light guide fiber components. The light guide fiber components focus monochromatic light generated by all the monochromatic light assemblies to colorimetric cups corresponding to the microplate readers respectively through different optical paths, and optical signals are converted into electrical signals through a photocell. The light guide fiber components comprise multi-channel optical fiber bundles and optical focus mechanisms. The input ends of the multi-channel optical fiber bundles receive the monochromatic light output by the monochromatic light assemblies, and the optical focus mechanisms are located at the output ends of the multi-channel optical fiber bundles and are focused to the centers of the colorimetric cups of the corresponding channels. By means of the monochromator, two to twelve bundles of monochromatic light of any input wave length and even in energy distribution can be obtained at any time, the response time is short, and no mechanical movement mechanism is needed.
