摘要:
A probe light source with uniform spectral output is required to obtain constant signal‐to‐noise ratio in absorption spectra taken with an optical multichannel analyzer. Suitable filters to balance the spectrum of the flash‐lamp source discussed here are unavailable. Instead a device is proposed which equalizes the spectrum of the probe source after it has been dispersed by the spectrograph of the optical multichannel analyzer.
