A liquid filter has a hollow-cylindrical filter element to be flowed through in radial direction from an exterior to an interior of the filter element by a fluid to be filtered. The parent material system may include a low temperature material having a relatively low melting point and a high temperature material having a relatively high melting point. The distal portion includes a tip defining a taper in the distal direction toward the longitudinal axis and terminating at a distal opening. Specifically, a satisfactory CD shift value can be obtained when the flow ratio is from 0. Also described are electronic assemblies such as solar cells using the various compositions and related methods. A method of visualization of eye anatomy includes engaging a patient’s head with a housing, positioning at least one camera coupled to the housing adjacent an eye, wherein the camera has a view vector along a first axis when in a first position, and moving the camera to a second position with a view vector along a second axis that is offset from the first axis.
