A method of producing an optical device from a volume of a curable composition, includes the following steps: —polymerizing a first portion of the volume by irradiating an external surface of the volume with a light irradiation, thereby increasing a transmittance of the first portion for the light irradiation; —polymerizing a second portion of the volume by irradiating the second portion with the light irradiation through the external surface and the polymerized first portion, wherein the light irradiation has a light intensity varying over the external surface between a first light intensity and a second light intensity distinct from the second light intensity. A corresponding system is also described.

A system and method for forming a seal member onto a substrate from a material is disclosed. The system includes a mold comprising an ultraviolet transmissible material, the mold having a first portion and a second portion operatively coupled to the first portion, the first portion having a first cavity, a second cavity, and a channel extending from an outer surface of the mold to the second cavity. The first cavity has a first shape that is complementary to a first side of the substrate and the second cavity has a second shape that is complementary to the seal member. The system also includes an applicator in fluid communication with the channel, where the applicator is configured to provide the material to the second cavity through the channel, and an ultraviolet irradiation device configured to irradiate the mold with ultraviolet light to cure the material when the material is provided to the second cavity, such that the seal member is formed on the substrate.

An imprint apparatus that performs a supply step of supplying an imprint material onto each of shot regions adjacent to each other on a substrate and, after the supply step, execute an imprint process including a contact step, a curing step, and a mold releasing step for each of the shot regions. The apparatus comprises an irradiator that irradiates the imprint material on the shot region with light in the curing step, and a light-shielding member that defines an irradiation region of the light from the irradiator, wherein the light-shielding member defines the irradiation region such that the imprint material in an end portion of a first shot region on a side of a second shot region adjacent to the first shot region is complementarily cured by light irradiation in the curing step performed on the second shot region.

A multi-station stereolithographic group, includes: support and movement apparatus for a modelling plate with respect to a fixed base facing the modelling plate, the fixed base including at least two work stations positioned in respective areas able to be reached by the modelling plate moved by the support and movement apparatus. Such a fixed base includes at least three work stations: at least one first station for forming an object, at least one second station for washing a formed object, at least one third station for stabilising a formed object.

A component mounting system for mounting a component on a substrate, the mounting system comprising a component supplying unit configured to supply the component; a substrate holding unit configured to hold the substrate in an orientation such that a mounting face for mounting the component on the substrate is facing vertically downward; a head configured to hold the component from vertically below; and a head drive unit that, by causing vertically upward movement of the head holding the component, causes the head to approach the substrate holding unit to mount the component on the mounting face of the substrate.
