Abstract

PURPOSE:To amend the error in case the error in wave length and display constantly the correct wave length by providing a photometer having a wave length driving mechanism applying a rotating angle corresponding to the wave length to the rotating stand on which the light scattering member. CONSTITUTION:The light from the light source 6 is passes through the detector 7, the amplifier 8, 9 and made as a light measuring output. The diffraction grating 2 is mounted on the rotating stand 1 and is given a rotating angle by a sign bar mechanism. The photometer is set at the check mode, so that a filter 12 most suitable for the correction of the first wave length lambda1 namely the correction of the wave length lambda1 is selected and the energy peak of the wave length lambda1 is obtained to be memorized in the memory M2. The next wave length lambda2 is also corrected and at this time, the actual pulse number has error of f(lambda1)-f(lambda2) with respect to the pulse number equivalent to lambda1-lambda2 and it is memorized in the memory 14(M2). Said true wave length and the error value are operated 15 and memorized. The pulse of the pulse generator 17 is also transmitted to the error corrector 16 and in the correction formula, the wave length value in which the error in wave length computed from the equivalent error correction function is subtracted is indicated 18.
