Abstract
The spectrometer 1 is provided with a package 2 in which a light guiding portion 7 is provided, a spectroscopic module 3 accommodated inside the package 2, and a support member 29 arranged on an inner wall plane of the package 2 to support the spectroscopic module 3. The spectroscopic module 3 is provided with a body portion 11 for transmitting light made incident from the light guiding portion 7 and a spectroscopic portion 13 for dispersing light passed through the body portion 11 on a predetermined plane of the body portion 11, and the spectroscopic portion 13 is supported by the support member 29 on the predetermined plane in a state of being spaced away from the inner wall plane.
Claims9
A spectrometer comprising:
- a package on which a light-guiding portion is provided;
- a plurality of support members arranged in an inner wall plane of the package;
- a substrate to which the support members are jointed;
- a light detecting element mounted on the substrate;
- and
- a spectroscopic portion arranged between the support members opposed to each other for dispersing light made incident from the light-guiding portion and reflecting the light to the light detecting element,
- wherein the package is provided with a cap provided with the light-guiding portion and a stem in which the support members are arranged,
- an inner wall plane of the cap provided with the light-guiding portion opposes an upper plane of the substrate supported on the stem by the support members, and
- the spectroscopic portion is disposed between a lower plane of the substrate and the inner wall plane of the stem.
A spectrometer comprising:
- a package having a cap and a stem, the cap provided with a light incident portion;
- a support member disposed on the stem inside the package;
- a substrate integrated with the support member;
- a light detecting element mounted on the substrate;
- and
- a spectroscopic portion disposed between the substrate and the stem for dispersing light made incident from the light incident portion and reflecting the light to the light detecting element,
- an inner wall plane of the cap provided with the light incident portion opposes an upper plane of the substrate supported on the stem by the support members, and
- the spectroscopic portion is disposed between the lower plane of the substrate and the inner wall plane of the stem.
