Title:
SPECTROPHOTOMETER
Document Type and Number:
Japanese Patent JPH11183251
Kind Code:
A
Abstract:
To obtain an energy-absorbance spectrum without performing any troublesome operation.
An energy/dispersion angle converting section 23 finds the dispersion angles for energy step widths. A pulse signal generating section 22 finds the number of driving pulse signals required for finding the dispersion angles, and only sends the found number of pulses to a stepping motor 112. As a result, a diffraction grating 111 is rotated by energy step widths and monochromatic light having the wavelength corresponding to the rotation is taken out from the grating 111.
