摘要:
Sealed precision optical assemblies are provided by a mold-in-place (MIP) process wherein a glass preform for a lens or other optical element is molded and sealed directly into a one-piece metal support for the element in a single precision molding step. The product is a sealed glass/metal assembly incorporating a non-interlocking mechanical seal, the seal being hermetic yet free of supplemental sealing materials, and the optical axis of the glass element being at a precise predetermined location and in a predetermined alignment relative to one or more reference surfaces on the metal support

A die assembly includes a barrel die (4) having a tubular inner face, a sleeve (5) covering an outer peripheral surface of the barrel die, and a pair of core dies (1, 2) for pressing a preform inside the tubular inner surface of the barrel die. At least one of the paired core dies (1, 2) is slidable and guided along the tubular inner surface of the barrel die (4). The sleeve (5) does not transmit light having a wavelength of 5 µm or shorter and has a thermal conductivity of 70 W/m·K or greater.

There is provided an optical unit manufacturing method in which an optical element (45) is obtained by giving compression to an optical material using a mold (15, 16) after thermal softening of the optical material, and uniting of a frame unit (46) with the optical element (45) is required. The optical unit manufacturing method includes a step of forming the frame unit (46) as an integral part of the optical element (45) with reference to a position of the mold (15, 16) while holding the optical element (45) without opening the mold (15, 16) after forming of the optical element (45).

A holder/optical-element assembly (1) includes a cylindrical holder (10) and an optical element (20) disposed within the holder. The holder has an inner periphery surface (11) in which at least one opening (12) is provided, and the optical element is provided with at least one protrusion (21a) extending outward from the periphery of the optical element. Thus, the protrusion of the optical element is supported by the opening of the holder.

The invention relates to an optical element (100, 600) for a vehicle headlight, in particular a motor vehicle headlight, having a first head lens array (1, 6) which is a compressed as a single piece from a transparent material and at least one second head lens array (2, 3, 4, 5, 7) which is compressed as a single piece from the same or another transparent material. Said first head lens array (1, 6) and the second head lens array (2, 7) have respectively a connecting web (29, 39, 49, 59 / 79) which connects the at least one first head lens (11, 12, 62, 63) to a second head lens (21, 22, 71, 72).
