    Abstract: PROBLEM TO BE SOLVED: To provide a spectroscope capable of measuring a spectrum of an incident light at a high resolution and a large signal-to-noise ratio (S/N). SOLUTION: The spectroscope comprises a collimator lens 12 for converting a monochromatic ray passed through a slit 11 into parallel beams, an echelle grating 13 for diffracting the parallel beams in a predetermined direction, and a mirror 14 for totally reflecting the parallel beams emitted from the grating 13 toward the grating 13 to reciprocate the beams between the grating 13 and the mirror 14. In this case, the parallel beams reciprocated two times between the mirror 14 and the grating 13 are focused on a channel of a line sensor 15 via the lens 12.

    Abstract: PROBLEM TO BE SOLVED: To provide a spectroscope suitable for measuring a spectrum distribution of an excimer laser beam with a small size and a high performance capable of analyzing with a resolution of 0.1 pm or less similar to that of a large-sized spectroscope having a long focal length. SOLUTION: The spectroscope for measuring the spectrum distribution comprises an incident slit 3, a collimating optical system 2 for collimating a measured light passed through the slit 3, a diffraction grating 1 incident with a light collimated by the system 2 to diffract the light at a different diffraction angle in response to a wavelength, a focusing optical system 2 for converging a luminous flux diffracted by the grating 1, and an emitting slit or optical distribution detecting element 4 disposed at a focal surface of the system 2. In this case, a beam size enlarging optical system 5 for enlarging at least a diameter of the grating in a dispersing direction of the light collimated by the collimating optical system is disposed at least between the system 2 and the grating 1.

    Abstract: PROBLEM TO BE SOLVED: To provide an echell spectroscope in which both elements can be analyzed accurately even when a mixture sample of a trace element and a high concentration element is analyzed. SOLUTION: This echell spectroscope comprises an echell diffraction grating 4 for dispersing light from a light source 1 into high order spectral beams, an element 7 for separating the spectral beam dispersed through the echell diffraction grating 4 into spectral beams of different orders, and an image detector 10 comprising a CCD for detecting the order separated spectral beam wherein the image detector 10 is coupled with an actuator 12 for displacing the light receiving face through rotation, movement, or the like.
