Electrical power plays an important part and it is a critical contributing element for a most of the developments.Numerous power plants are accessible for the production of electrical energy and the most significant power sources are coal,solar power,wind,atomic,gas,Biomass,and so on.Power is also produced from plasma which is an ionized gas.It is said that while producing power from plasma because of some unprecedented reason the plasma begins to deteriorate which leads to the emission of enormous amount of gases including H-alpha which is of wave length 656.3 nm and it is necessary to design a filter to detect the H-alpha discharges.In this paper,a filter design for the H-alpha emission is discussed.
