在测量窄带通楔形滤光片的光谱透过率时,我们采用了一个宽度很小的狭缝,同时用分光光度计来记录滤光片本来具有的半宽度。为了使较多的能量进入系统,需要增加所采用的狭缝的宽度,因此我们采用了楔的非零宽度,从而改进了透过光的能量分布。实际上,我们必须根据狭缝宽度来积分楔的波长,半波长由其本来具有的数值增加到它的仪器数值。附加的理论区段表示仪器的半宽度取决于在边界以外透过率为零的具有正方形和正三角形通带的滤光片的狭缝宽度的情况。对于一个正方形的通带来说,除了仪器的数值并无增加以外,狭缝宽度可等于本来具有的半宽度。只有通带的倾斜度才能引起变化。较大的狭缝宽 When measuring the spectral transmittance of a narrowband pass-through wedge filter, we used a narrow width slit, while using a spectrophotometer to record the half width of the original filter. In order to get more energy into the system, it is necessary to increase the width of the slit used, so we have adopted a non-zero width of the wedge to improve the energy distribution of the transmitted light. In fact, we have to integrate the wavelength of the wedge according to the slit width, which is increased from its original value to its instrument value. The additional theoretical section indicates that the half-width of the instrument depends on the slit width of the filter with square and regular triangular passband with zero transmittance outside the boundary. For a square passband, the slit width may be equal to the half-width that would otherwise have been, except that there is no increase in the value of the instrument. Only the slope of the passband can cause changes. Larger slit width
