The utility model provides a linear dispersion optical lens for confocal spectral measurement, includes negative lens groups and positive lens group, the coaxial setting of negative lens groups and positive lens group, just negative lens groups is the same with the focus of positive lens group, and reverse the setting, negative lens groups establishes in light source one side for the image space chromatic dispersion produces, as the object space chromatic dispersion of positive lens group, positive lens group establishes in testee one side. This reality has the novel advantage that axial chromatic dispersion and wavelength have better linear relation that has. 种用于共焦光谱测量的线性色散光学镜，包括负透镜组和正透镜组，所述负透镜组和正透镜组同轴设置，且所述负透镜组和正透镜组的焦距相同，并反向设置，所述负透镜组设在光源侧，用于产生像方色散，作为正透镜组的物方色散，所述正透镜组设在被测物体侧。本实有新型具有轴向色散与波长有较好的线性关系的优点。
