    Abstract: PURPOSE:To measure in a wide range highly efficiently by scanning a part unnecessary for analysis at a high speed and a necessary part at a low speed in a light emitting spectrum wavelength driving device of a plasma light emission spectral analyzer. CONSTITUTION:A microcomputer 1 decides relation to the number of pulses required for deceleration/acceleration out of the number NT of pulses for the whole scanning driving distance and initializes 20-bit counters 5, 6 and a deceleration counter 4. A clock of 1kHz is inputted from a clock generator 27 to an up/down counter 14 on the basis of a start instruction. The output of a D/A converter 15 is increased in proportional to the increment of the counter 14 and frequency proportional to input current is obtained by a V/F converter 17. When the output of an amplifier 16 reaches a voltage corresponding to high speed frequency, constant speed operation is started and a pulse motor 36 is rotated by a pulse motor driving circuit 35. On the contrary, the driving device starts decelerating operation at a point close to the end point of the measuring range and the motor is finally stopped.

    Abstract: PURPOSE:To obtain a high-precision spectrophotometer having corrected variance in grating constant by using a direct shaft driving type grating spectrophotometer which is mechanically simple and correcting variation of a diffraction grating automatically. CONSTITUTION:The spectrophotometer M is driven from a short-wavelength side, and after light of lambda1 is detected by a photodetector PD, wavelength driving is further carried on to detect light of lambda2. The difference DELTAtheta between both angle positions is obtained by counting input pulses to a diffraction grating driving pulse motor PM from the detection of the lambda1 to the detection of the lambda2. In equations 1 and 2, a diffraction constant (d) contains an error and is unknown, and thetao is also unknown. When the number of grating lines is normal, i.e. No/mm., the DELTAtheta in the equation 2 is obtained by calculation. The number of input pulses to the pulse motor corresponding to the DELTAtheta is calculated and stored in the memory of a computer previously. Which one in the memory the number of pulses corresponding to the DELTAtheta corresponds actually to is retrieved, the grating constant is found immediately and a wavelength origin is determined by the equation 1. Further, a constant 2dcosalpha is also fixed and then wavelength lambda is determined by the rotational angle of the diffraction grating.
