    • The invention relates to a method for producing a plurality of microlenses (10) made of a lens material, involving the following steps, in particular involving the following sequence: - applying the lens material provided for embossing the microlenses (10), in particular a curable fluid (2), preferably a polymer, in fluid form to a plurality of first lens forms (5) distributed on a first embossing side (3o) of a first plunger (3) in order to emboss the microlenses (10), - moving the first plunger (3) and a second plunger (4), which is arranged substantially parallel, namely in an X-Y plane, and opposite the first plunger (3), towards each other in a Z-direction that runs substantially perpendicular to the X-Y plane, - embossing the microlenses (10) by shaping and curing the lens material, the shaping being performed by moving the first and second embossing side (3o, 4o) towards each other in a Z-direction up to a thickness Di of the lens material, characterised in that the lens material of each microlens (10) is separated from the lens material of every adjacent microlens (10) in the X-Y plane at least during curing. The present invention further relates to a corresponding device.
    • 用于从透镜材料制造多个微透镜的装置和方法。 该方法包括:将用于将微透镜压花的透镜材料应用于分布在第一模具的第一压花侧上的多个第一透镜模具,用于压印微透镜,使第一模具和第二模具基本平行地移动, XY平面,并且与第一模具相对,在基本上垂直于XY平面的Z方向上彼此顶部,通过使透镜材料成形和固化来压印微透镜,通过移动第一和第二压花 这些透镜材料在Z方向上达到透镜材料的厚度D1,其中至少在固化期间每个微透镜的透镜材料与在XY平面中相邻的每个微透镜的透镜材料分离。
