A fiber optic illuminator is provided comprising an optics bed, a light source, a collimating lens, and a condensing lens. The light source is mounted in a fixed position with respect to the optics bed. The collimating lens is mounted in a fixed position with respect to the optics bed and collimates at least a portion of the light from the light source. A condensing lens receives the substantially collimated light output and focuses the collimated light output to optically couple to an optical fiber. The condensing lens may be mounted on an adjustable mount. The tolerances of the fixed optical elements i.e. light source and collimating lens allow the fixed optical elements to be positioned with a minimal amount of variation where the variation is determined by manufacturing tolerances associated with these individual elements and their mounts and couple them to the optics bed.
