Hyperspectral camera lens unit and hyperspectral camera

2:

• The hyperspectral camera lens unit according to claim 1,
• wherein the Fabry-Perot interference filter is disposed at a position where a chief ray passing through an outer edge of an imaging region of the light formed by the second lens portion intersects an optical axis of the light.

3:

• The hyperspectral camera lens unit according to claim 1,
• wherein the first aperture is located on a side of the incident portion with respect to the pair of mirror portions.

4:

• The hyperspectral camera lens unit according to claim 1,
• wherein the optical system further includes a second aperture disposed between the Fabry-Perot interference filter and the first lens portion or between the Fabry-Perot interference filter and the second lens portion.

5:

• The hyperspectral camera lens unit according to claim 4,
• wherein the second aperture is configured as an opening formed in a support, and
• the Fabry-Perot interference filter is fixed to the support.

7:

• The hyperspectral camera lens unit according to claim 1,
• wherein when viewed in the optical axis direction, an area of an incident region of the light at an incident position on the first aperture is equal to or less than 110% of an area of the first aperture.

8:

• The hyperspectral camera lens unit according to claim 1,
• wherein the optical system further includes an additional optical system that is disposed between the Fabry-Perot interference filter and the first lens portion, and that reduces the width of the light.

9:

• The hyperspectral camera lens unit according to claim 1,
• wherein the optical system further includes an additional optical system that is disposed between the Fabry-Perot interference filter and the first lens portion, and that collimates the light.

10:

• The hyperspectral camera lens unit according to claim 9,
• wherein the additional optical system reduces the width of the light.

11:

• The hyperspectral camera lens unit according to claim 1,
• wherein the Fabry-Perot interference filter includes a substrate including a first surface and a second surface opposite the first surface, and a first laminated structure disposed on the first surface, and
• the first laminated structure includes a first laminate disposed on the first surface and including one of the pair of mirror portions, and a second laminate disposed on a side opposite the substrate with respect to the first laminate and including the other of the pair of mirror portions.

13:

• The hyperspectral camera lens unit according to claim 1,
• wherein the Fabry-Perot interference filter includes a first substrate including a first surface, a second substrate including a second surface facing the first surface, one of the pair of mirror portions formed on the first surface, and the other of the pair of mirror portions formed on the second surface.

14:

• The hyperspectral camera lens unit according to claim 1,
• wherein the first aperture is formed by providing a light-shielding layer in a region of the Fabry-Perot interference filter other than a light-transmitting region while not providing the light-shielding layer in the light-transmitting region.
