Ultraviolet irradiation device

Abstract

To provide an ultraviolet irradiation device in which an optical axis can be easily adjusted.SOLUTION: An irradiation device (ultraviolet irradiation device) 1 comprises, as one unit: an ultraviolet light source unit 30 that emits ultraviolet light; a first optical mount section 34 that allows detachable installation of a first optical member for performing first optical processing on the ultraviolet light emitted from the ultraviolet light source unit 30; and a second optical mount section 36 that allows detachable installation of a second optical member for performing second optical processing on the ultraviolet light that has passed through the first optical mount section 34.SELECTED DRAWING: Figure 3

Claims

[Claim 1] A UV light source that emits ultraviolet light, A first optical mount section to which a first optical member that performs a first optical process with respect to the ultraviolet light emitted from the ultraviolet light source section can be detachably attached, A second optical mount portion on which a second optical member that performs a second optical treatment on the ultraviolet light that has passed through the first optical mount portion can be detachably attached. It is provided as a single unit, The first optical mount portion houses the first optical member within a cylindrical first mount body. The first optical component comprises a collimating lens and a first pinhole body having a first through-hole with a predetermined cross-sectional shape. The second optical mount portion houses the second optical member within a cylindrical portion, and the second optical member is a second pinhole body having a second through-hole that has the same shape as the first through-hole of the first pinhole body but is smaller than the first through-hole.
