## Abstract

A spectroscope comprises a package provided with a light entrance part, a plurality of lead pins penetrating through a support part opposing the light entrance part in the package, and a spectroscopic module supported on the support part within the package. The spectroscopic module has a light detection unit provided with a light transmission part for transmitting therethrough light incident thereon from the light entrance part and a spectroscopic unit, secured to the light detection unit so as to be arranged on the support part side of the light detection unit, including a spectroscopic part for spectrally resolving the light transmitted through the light transmission part while reflecting the light to a light detection part. The lead pins are fitted into fitting parts provided with the light detection unit and electrically connected to the light detection part.

## Claims

### Claim 1

A spectroscope comprising:
a package provided with a light entrance part;
a plurality of lead pins penetrating through a support part opposing the light entrance part in the package; and
a spectroscopic module supported on the support part within the package;
wherein the spectroscopic module has:
a light detection unit provided with a light transmission part for transmitting therethrough light incident thereon from the light entrance part; and
a spectroscopic unit, secured to the light detection unit so as to be arranged on the support part side of the light detection unit, including a spectroscopic part for spectrally resolving the light transmitted through the light transmission part while reflecting the light to a light detection part of the light detection unit; and
wherein the lead pins are fitted into fitting parts provided with the light detection unit and electrically connected to the light detection part.

### Claim 2 (depends on 1)

A spectroscope according to claim 1, wherein the spectroscopic module further comprises a spacer arranged between the light detection unit and the spectroscopic unit; and
wherein the spectroscopic unit is secured to the light detection unit with the spacer.

### Claim 4 (depends on 1)

A spectroscope according to claim 1, wherein the spectroscopic unit is secured to the light detection unit while in contact therewith.

### Claim 5 (depends on 1)

A spectroscope according to claim 1, wherein the fitting parts are holes penetrating therethrough from the spectroscopic unit side to a side opposite thereto; and
wherein the lead pins are inserted into the fitting parts within the package.

### Claim 6 (depends on 1)

A spectroscope according to claim 1, wherein the fitting parts are depressions opening to the spectroscopic unit side; and
wherein the lead pins have end parts arranged at the fitting parts within the package.
