A light pipe for an electronic device, such as a barcode-reading device, can include a plurality of light-redirecting surfaces that are each positioned to receive light from a light source within the interior portion of the barcode-reading device and to redirect the light toward an optical element positioned on an exterior surface of the barcode-reading device. The plurality of light sources and the plurality of light-redirecting surfaces can collectively produce a uniform light output at the optical element when all of the plurality of light sources are activated. The light pipe can also include a plurality of optical barriers interspersed between the plurality of light-redirecting surfaces to isolate light from individual light sources. This allows for a segmented light output to be projected onto the optical element. The light pipe can be made from a flexible and resilient material, thereby allowing the light pipe to provide shock absorption.

An apparatus for ophthalmic procedures contains a source of aiming and treatment laser beams, folded mirrors and lens arrays to cause the formation of a static pupil on a delivery mirror for observation and treatment by an operator of the apparatus.

A system to remove cladding light from an optical fiber that includes a core and a cladding that surrounds the core. A volume of an index-matching material contacts an exterior surface of the cladding along a contact length of the optical fiber. The index-matching material has a refractive index that substantially matches a refractive index of the cladding at a predetermined clamping temperature and has a refractive index with a negative temperature coefficient, such that the index matching material distributively removes light from the cladding along the contact length based on the temperature of the index matching material that contacts the cladding.
