Essential components permit individual use for special research projects. Light source and holder for cells widely separated. No temperature influence. Direct reading—no compensation method. Rapid location of absorption maxima and minima Repeat settings of smallest slit widths possible due to new design friction-free slit mechanism. Projected wave-length and transmittance scales (4 ft.) allow parallax-free reading. Built-in chopper diaphragm eliminates dark current and assures strict linearity. Adjustable damping device for galvanometer reduces fluctuation at highest amplification. Direct operation on 1 10-volt A.C. No battery necessary. Measuring range 200 to 2 5 0 0 π\μ.
