Injection molding of monolithically integrated optical components is disclosed. In one embodiment, an injection molding system includes a moldplate having an array of specially designed cavities. In at least one cavity, different types of photo-curable optical materials are injected in an ordered sequence. In a first instance, a lens material is injected into the cavity and subsequently cured to form a predetermined lens element at the base of the cavity. In a second instance, a filter material is injected into the cavity above the already formed lens element. The filter material is also cured, and an optical filter is formed stacked onto the lens element and contained within sidewall of the cavity. In this manner, a complex optical component having an optical filter automatically aligned with, and monolithically integrated into, a lens element is readily formed in a single injection molding process.
