A new plane grating monochromator is described which uses off-axis parabolas. The optical arrangement is such that extremely sharp spectral line images of constant curvature are realized at mirror angles large enough to prohibit the possibility of multiple dispersion.
描述了一种使用离轴抛物线的新型平面光栅单色仪。其光学装置能在足够大的镜角下实现具有恒定曲率的极其清晰的光谱线图像，从而排除了多重色散的可能性。
