Abstract: A fixed position athermal optical system includes a first lens having a negative refractive power, and a second lens having a positive refractive power, where a temperature coefficient of refractive index for the respective lens materials is configured to mitigate the effect of temperature changes on the operation and performance of the optical system.

Abstract: A compact camera device includes an image sensor and a micromolding lens stack. The compact camera device may include a partial lens holder holding a first micromolding lens that supports the micromolding lens stack. The compact camera device may include a monolithic lensing element including a support portion and a lensing portion that supports the micromolding lens stack.

Abstract: A camera module includes a printed circuit, an image sensor, a lens assembly, and a multi-layer shield. The lens assembly is configured to focus image light to the image sensor. The multi-layer shield is disposed around the lens assembly and around the image sensor. The multi-layer shield includes a shield layer and a light-blocking layer. The shielding layer is configured to block electromagnetic interference (EMI). The light-blocking layer is configured to block ambient light from becoming incident on the image sensor and the lens assembly.

Abstract: A compact camera device with a lens assembly that does not include any lens barrel or lens holder. The lens assembly includes a first micromolding lens and a second micromolding lens. The first micromolding lens includes a first side and a second side that is opposite to the first side, the first side including a first mounting surface. The second micromolding lens includes a third side and a fourth side that is opposite to the third side, the fourth side including a second mounting surface that is directly affixed to the first mounting surface to form at least a portion of a micromolding lens stack comprising the first micromolding lens and the second micromolding lens in optical series. The micromolding lens stack is a self-supporting structure fixed in place within the camera device without the use of a lens barrel or a lens holder.
