Abstract

PURPOSE:To make it possible to execute the wavelength scanning with higher accuracy, by constituting so that a rotary axis of the diffraction grating can move forward and backward against the line connecting the incident and emitting slits, and making it move finely so as to satisfy the prescribed condition by being interlocked with the wavelength scanning. CONSTITUTION:In a simple rotation concave surface diffraction grating spectroscope, the concave surface diffraction grating 1 is fixed to the pin 9 which has been fitted into the fixed guide 8. When a screw shaft 4 is rotated, a nut which is spirally fitted into the screw shaft 4 is moved, and a bar 6 which is fixed to the nut 7 so as to freely rotate is rotated around a rotary axis 5 of the diffraction grating 1, and simultaneously is moved forward and backward. The diffraction grating 1 is interlocked with rotation by the sine bar mechanism, and finely moves forward and backward around both the ends of the scanning wavelength area, and in the center area, respectively. Accordingly, the wavelength scanning of high accuracy can be executed.
