sely proportional to thesquare root of the surface, so that in spectral energy work, wherethe bolometer strip is narrow, the sensitiveness attainable throughthe bolometer is limited. Since writing the previous paper the present instrument hasbeen considerably changed, and the experience gained… … ,1 amp. holder, the one exposed to radiation is first soldered in place,using rosin for a flux. The unexposed strip is made a little longer,so that it will have a slightly greater resistance, which by subse-quent resoldering is made equal ro that of the exposed strip. Thisis a difficult task when…
