OMA-CH1 is an Optical Multichannel Analyzer manufactured employing the PCD linear image sensor. This paper develop the design of its software and its use. The system can sample and analyze spectrum immediately and with figuer, can measure wavelenths and relative intensities of the spectrum precicely and quickly.and can study the time nature of light sourses. It has quite strong functions for processing spectrums and a capability of packing and dumping massage. Its menu is in chinese, the operation is conveniently. The system work in the range of the visible light and adapt to different light sources of different intensities.
