hrGRIN lens assembly. (a) SolidWorks schematics of hrGRIN lens assemblies. GRIN lenses (l = 1.7 mm, d = 500 µm) are affixed to a glass window (l = 600 µm, d = 500 µm) and #1.5 cover glass (d = 3 mm) with NOA 71 optical adhesive. A 1-mm thick stainless-steel washer (ID = 1.7 mm, OD = 3 mm) was permanently affixed to the cover glass. The stainless-steel washer portion of the assembly facilitated loading of the assembly into a cannula holder for stereotaxic implantation. (b) Completed assembly next to a small coin (US dime) for size comparison.
