  • Projector having stacked optical layers
    Patent number: 10582146
    Abstract: A projector includes a semiconductor die including a digital micromirror device; and a first integral optical layer attached to the semiconductor die. The first integral optical layer includes a first optical lens and a first diffractive optical element. A second integral optical layer is attached to the first integral optical layer. The second integral optical layer includes an aperture stop and a second diffractive optical element. A third integral optical layer is attached to the second integral optical layer. The third integral optical layer includes a second optical lens and a light source mount. The semiconductor die, the first integral optical layer, the second integral optical layer and the third integral optical layer are stacked to form an optical path through the first and second diffractive optical elements, reflect off the digital micromirror device, and pass through the first optical lens, the aperture stop and the second lens.
