Web7 sep. 2024 · Thus, a gradient index lens is what its namesake suggests: a lens where its refractive index quadratically varies radially according to a gradient (Figure 2a). When engineered to the appropriate length, this allows light to be focused onto a point (Figure 2b). GRIN lenses can be machined as small rod-like shapes which can be coupled with ... WebGRIN lenses are typically limited in diameter (0.5–1mm). Thus, imaging with GRIN lenses provides a relatively small field of view, compared to cortical windows, and the implantation of a large GRIN lens can lead to tissue damage, compared to an optical cannula. However, a GRIN lens is the only imaging probe available to image with cellular ...
