Claims

[Scope of utility model registration request]

(1) The light that enters from the entrance, passes through the lens, slit, and first concave mirror, and is separated by the angle analysis grating is the light that enters the second. In the spectrometer, the lens, the slit, the first and second concave mirrors, and the diffraction grating are configured such that the light is condensed by a concave mirror, reaches an exit port, and is received by an image sensor mounted on a substrate. The second concave mirror is arranged to guide light on the same plane, and the second concave mirror is arranged so that the light guided on the same plane until reaching the second concave mirror is reflected at an angle of 1 with respect to the plane and reaches the exit port. 2. A spectrometer, characterized in that a plane mirror is placed between the concave mirror of No. 2 and the exit port, the mirror having an angle with respect to the plane.

(2) The spectrometer according to claim 1, wherein the angle of reflection from the plane mirror by the plane mirror is 90°.

(3) Utility model registration according to claim 1 or 2, characterized in that the exit port is located approximately at the center of a wall surface that is approximately parallel to the plane on which the light of the spectrometer is guided. spectrometer.
