Abstract
The present invention relates to an optical component and a transparent body used in the optical component. The optical component includes at least one optical element that radiates ultraviolet light, and a package that accommodates the optical element. The package includes a mounting substrate on which the optical element is mounted, and a transparent body that is bonded to the mounting substrate with an organic-based adhesive layer therebetween. The package has a structure in which the ultraviolet light is transmitted through the transparent body but not guided to the adhesive layer, and the ultraviolet light does not directly come into contact with the adhesive layer.
Claims12
An optical component including:
- at least one optical element configured to emit ultraviolet light;
- and
- a package in which the optical element is housed, the package including:
- a mounting substrate on which the optical element is mounted;
- and
- a transparent body that is joined onto the mounting substrate via an organic-based adhesive layer, the transparent body defining a lens body including a raised pedestal provided on the adhesive layer, and the package having a structure in which the ultraviolet light is not guided to the adhesive layer through the transparent body, and the ultraviolet light does not directly strike the adhesive layer,
- wherein an angle θ defined between an upper surface of the pedestal and a lower section of the lens body is greater than or equal to 80 degrees and less than 90 degrees.
A transparent body employed in an optical component, the optical component being provided with a package, the package including:
- at least one optical element configured to emit ultraviolet light;
- and
- a mounting substrate on which the optical element is mounted, the transparent body being joined onto the mounting substrate via an organic-based adhesive layer, and the transparent body including:
- a pedestal fixed onto the mounting substrate;
- a lens body integrally formed on the pedestal;
- and a recess having a lower surface opening, the recess being provided in the pedestal,
- wherein an angle θ defined between an upper surface of the pedestal and a lower surface of the lens body is greater than or equal to 80 degrees and less than 90 degrees.
