分辨率仍受限于电子束的波长，但此波长远小于可见光的波长。
Resolution is still limited by the wavelength of the electron beam, but this wavelength is much smaller than that of visible light.
这种单色仪由于波长精度高、重复性好、分辨率高而杂散光却很小，因此具有特殊用途。
As wavelength precision and resolution of the instrument is high, but the stray light is less, and the repeatability is good, it has special purpose.
在保证频谱分辨率不变的情况下，通过减少参与FFT运算的点数来缩短运算时间，提高激光波长测量装置的反应速度。
Under the condition of unchanging the spectrum resolution, the latency of the laser wavelength measurement system is improved by reducing the samples of FFT operation.
