Abstract

Devices and methods for transmitting light through an aperture in a surface substantially without leakage. In one embodiment, the device comprises an optical relay structure having an end configured to transmit light, and an opaque collar positioned around the end and configured to reorient to conform to the surface when the end and the aperture are aligned. In another embodiment, the device comprises an optical relay structure having an end configured to transmit light, and an opaque collar positioned around the end and spring-biased relative to the end, so that the opaque collar is forced against the surface when the end and the aperture are aligned. The devices further may include a stop mechanism for limiting movement of the opaque collar, a registration mechanism for aligning the end and the aperture, and a light source and/or a detector for generating or detecting light, among others.
