Abstract
An optical probe (10) includes an inner tube (30), and a light-redirecting element (54) disposed at a distal end (56) of the inner tube. The light-redirecting element is supported at the distal end by an affixing structure (57) not attached to an optically-working surface (58) of the light-redirecting element.

An optical probe comprising:
- an inner tube;
- and
- a light-redirecting element disposed at a distal end of the inner tube, wherein the light-redirecting element is supported at said distal end by an affixing structure not attached to an optically-working surface of the light-redirecting element, wherein the inner tube comprises at least two corresponding inner tube sections separable from one another along respective joint lines co-axially extending in a direction along a longitudinal axis over an entire longitudinal length of the inner tube, wherein the light-redirecting element comprises a prism, wherein the affixing structure comprises respective protrusions from the inner tube sections, each protrusion having a support surface attached to a corresponding lateral surface of the prism, wherein the affixing structure further comprises respective layers of adhesive between the support surfaces and the lateral surfaces of the prism.
