    摘要： A Fresnel lens can be adhered to a window in an optical apparatus by liquid optically clear adhesive (LOCA). However, during adhesion the LOCA may spill over into grooves of the Fresnel lens, and the grooves can carry the LOCA into an active area of the lens potentially causing visual artifacts and altering the functional and cosmetic optical qualities of the lens. In examples of the disclosure, one or more grooves along the circumference of a surface of the lens surrounding inner grooves of the Fresnel lens can form a barrier ring that prevents the LOCA from reaching the inner grooves.

    摘要翻译： 菲涅尔透镜可以通过液体光学透明粘合剂（LOCA）粘附在光学装置中的窗口上。 然而，在粘合过程中，LOCA可能会溢出到菲涅尔透镜的凹槽中，凹槽可以将LOCA运送到透镜的有效区域，从而潜在地导致视觉伪像并改变透镜的功能和美观光学质量。 在本公开的实例中，围绕菲涅耳透镜的内槽的透镜的表面的圆周的一个或多个凹槽可以形成防止LOCA到达内槽的阻挡环。
