Abstract
A method of making an integrated depth sensor window lens, such as for an augmented reality (AR) head set, the depth sensor window lens comprising a sensor lens and an illuminator lens separated by an opaque dam. The method uses a two-shot injection molding process, a first shot comprising an optically clear polymeric material to form the sensor lens and the illuminator lens and the second shot comprising an opaque polymeric material to form the separator of the two.
Claims20
In a head mountable device wearable by a user, a depth sensor window lens, wherein a back side of the depth sensor window lens is positioned to be proximate to eyes of the user and a front side of the depth sensor window lens is positioned to be distal to the eyes of the user on an opposite side of the depth sensor window lens, the depth sensor window lens comprising:
- a sensor lens comprising an infrared (IR) transparent polymer and having a front surface on the front side of the depth sensor window lens with a root mean square (RMS) surface finish of no more than 6 nanometers (nm);
- an illuminator lens comprising an IR transparent polymer and having a front surface on the front side of the depth sensor window lens with an RMS surface finish of no more than 6 nm;
- and
- a dam between the sensor lens and the illuminator lens on the front side of the depth sensor window lens, the dam comprising an opaque polymer and having a front surface within 10 nm of the front surface of the sensor lens and the front surface of the illuminator lens.
A head mountable device (HMD) for augmented reality (AR) comprising:
- a visor lens;
- and
- a depth sensor window lens integrated into the visor lens, wherein a back side of the depth sensor window lens is positioned to be proximate to eyes of a user and a front side of the depth sensor window lens is positioned to be distal to the user on an opposite side of the depth sensor window lens, the depth sensor window lens comprising:
- a sensor lens comprising an infrared (IR) transparent polymer and having a front surface on the front side of the depth sensor window lens with a root mean square (RMS) surface finish of no more than 6 nanometers (nm);
- an illuminator lens comprising an IR transparent polymer and having a front surface on the front side of the depth sensor window lens with an RMS surface finish of no more than 6 nm;
- and
- a dam between the sensor lens and the illuminator lens on the front side of the depth sensor window lens, the dam comprising an opaque polymer and having a front surface within 10 nm of the front surface of the sensor lens and the front surface of the illuminator lens.
