窄带干涉滤光片 meaning in English

spike interference filter

Effect of error auto - compensation and error of the extremely narrow - band interference filter in dwdm system
Dwdm极窄带干涉滤光片的误差与自动补偿效应
The apparatus uses 880 , 950nm nir led as light source , interference filter as homochromy device , si photronic as detector . digital signal comes from ad transformation , processed by microprocessor system
以880 、 950nm的近红外led为光源， 14个窄带干涉滤光片为单色器，以硅光电池为检测器，经ad转换得到数字信号，送单片机处理。
The calculated density of mgf2 with iad was increased from 0 . 70 for conventional process to 0 . 97 . meanwhile we find that the spacer layer has a great influence on the spectral shift . the further the layers are away from the spacer , the less the effect ; in the same way , the iad reduces the spectral shift of nb205 / sio2 narrow band interference filters from 29 . 4nrn to 12 . 4nm ; the iad reduces the spectral shift of tio2 / sio2narrow band interference filters from 24 . 7nm to 8 . 4nm
同时发现间隔层对光谱漂移的影响最大，越远离间隔层的膜层，其影响越小；而nb _ 2o _ 5 sio _ 2多层膜窄带干涉滤光片漂移从常规工艺的29 . 4nm降到12 . 4nm ； tio _ 2 sio _ 2多层膜窄带干涉滤光片漂移从常规工艺的24 . 7nm降到8 . 4nm 。
