The interlayer penetration depth in layered superconductors may be determined from scanning Superconducting QUantum Interference Device (SQUID) microscope images of interlayer Josephson vortices. We compare our findings at 4 K for single crystals of the organic superconductor κ-(BEDT-TTF)2Cu(NCS)2 and three near-optimally doped cuprate superconductors: La2-xSrxCuO4, (Hg,Cu)Ba2CuO4+δ, and Tl2Ba2CuO6+δ.
