    • A device for fabricating a lens includes a mold which molds UV curable resin applied onto a base; an UV source which irradiates the UV curable resin with UV light; and an irradiation rate controller which controls, according to position, irradiation rates at which the UV curable resin is irradiated with the UV light. Preferably, the irradiation rate controller controls the irradiation rates such that an irradiation rate at which a central area of the UV curable resin is irradiated is higher than an irradiation rate at which a peripheral area of the UV curable resin is irradiated. Preferably, the mold provides an empty space around the UV curable resin. According to one embodiment, the irradiation rate controller is a mask which has a higher transmittance to the UV light at a central area than at a peripheral area. According to another embodiment, the irradiation rate controller is a diaphragm which expands an irradiation area from the central area of the UV curable resin to the peripheral area of the UV curable resin. According to still another embodiment, the irradiation rate controller is an optical system whose focal length can be controlled. According to still another embodiment, the irradiation rate controller moves an irradiation area in a radial direction from the central area of the UV curable resin to the peripheral area of the UV curable resin.
    • 用于制造透镜的装置包括:将施加到基底上的UV固化树脂模制的模具; 用UV光照射UV固化树脂的UV源; 以及照射速度控制器,其根据位置控制用UV光照射UV固化树脂的照射速率。 优选地,照射速度控制器控制照射速率,使得照射紫外线固化树脂的中心区域的照射速率高于照射紫外线固化树脂的周边区域的照射速度。 优选地,模具提供围绕UV可固化树脂的空白空间。 根据一个实施例,照射速度控制器是对中心区域的UV光具有比周边区域更高的透射率的掩模。 根据另一实施例,照射速度控制器是将UV固化树脂的中心区域的照射区域扩展到UV固化树脂的周边区域的隔膜。 根据另一个实施例,照射速度控制器是可以控制其焦距的光学系统。 根据另一实施例,照射速度控制器将从UV固化树脂的中心区域的径向的照射区域移动到UV固化树脂的周边区域。
