Abstract
The optical sensor package comprises an optical sensor device with a sensor element arranged inside a housing comprising a cap. A diffuser is arranged in an aperture of the cap opposite the sensor element and prolongs the cap in the aperture or closes the aperture. The method comprises forming a cap with an aperture, arranging a diffusing material in the aperture, thus forming a diffuser, and after forming the diffuser, arranging an optical sensor device with a sensor element inside a housing that includes the cap, such that the sensor element is opposite the diffuser.
Claims13
An optical sensor package, comprising:
- an optical sensor device with a sensor element,
- a cover of the optical sensor device, and
- a housing comprising a cap with an aperture, the optical sensor device being arranged inside the housing,
- a diffuser is arranged in the aperture opposite the sensor element,
- the diffuser prolongs the cap within the aperture or closes the aperture, and
- the cover being arranged at a distance from the diffuser, wherein the distance is adjusted with respect to the cover in such a manner that a maximal angle of incidence of 40° is obtained at the sensor element for radiation of at least one wavelength that is to be detected.
