摘要： A phase mask (15) for modulating a collimated light beam passing therethrough, the light beam being diffracted to photoinduce a refractive index profile in a photosensitive optical medium, the phase mask (15) comprises a substrate (17) having an outer surface provided with a plurality of parallel grating corrugations (19). The grating corrugations (19) have a non-uniform relief depth across the outer surface for photoinducing a non-uniform refractive index profile in the photosensitive optical medium. The non-uniform relief depth is defined by a variable thin film layer (21) of variable thickness overlaying the substrate (17). The grating corrugations (19) can either be etched into the variable thin film layer (21) itself or be etched into the substrate (17), with the variable this film layer (21) being deposited on it after etching. Methods to make such phase masks are also provided.
摘要翻译：一种用于调制通过其中的准直光束的相位掩模（15），所述光束被衍射以光敏光敏介质中的折射率分布，所述相位掩模（15）包括具有外表面的基板（17）多个平行光栅波纹（19）。光栅波纹（19）在外表面上具有不均匀的浮雕深度，用于光敏光敏介质中的不均匀折射率分布。不均匀的浮雕深度由覆盖基板（17）的可变厚度的可变薄膜层（21）限定。光栅波纹（19）可以自身蚀刻到可变薄膜层（21）中，或者蚀刻到衬底（17）中，在蚀刻之后可以将该膜层（21）沉积在其上。还提供了制造这种相位掩模的方法。

摘要： An imaging lens includes a lens barrel, a plurality of lens elements and a spacer. The lens elements are disposed in the lens barrel. The spacer is disposed between the lens barrel and one of the lens elements or between two adjacent lens elements. The spacer is ring-shaped and includes an inside layer and two outside layers. The two outside layers are attached on opposite sides of the inside layer, respectively. The spacer has an object-side surface, an image-side surface and a first inner ring-shaped oblique surface. The object-side surface and the image-side surface are formed outside the two outside layers in parallel and oriented toward an object side and an image side of the lens elements, respectively. The first inner ring-shaped oblique surface is formed at an inner periphery of the spacer and connected to at least one of the object-side surface and the image-side surface.
摘要翻译：成像透镜包括透镜镜筒，多个透镜元件和间隔物。透镜元件设置在镜筒中。间隔件设置在透镜镜筒与透镜元件中的一个之间或两个相邻透镜元件之间。间隔件是环形的并且包括内层和两个外层。两个外层分别附着在内层的相对侧上。间隔件具有物体侧表面，图像侧表面和第一内环形倾斜表面。物体侧表面和图像侧表面平行地形成在两个外层的外侧，并且分别朝向透镜元件的物体侧和像侧。第一内环形斜面形成在间隔件的内周，并与物侧表面和像侧表面中的至少一个连接。
