ILLUMINATION PORT FOR AN OPTICAL DEVICE

摘要

Illumination in an optical device (10) is provided via a light conductor (44) combined with a light source (70) or light collecting device detachably mounted to the optical device (10). A seal (94) between the light conductor (44) and the optical device housing (14) prevents moisture and other contaminants from entering the housing (14). The light source (70) or light collecting device may be removable and interchangeable to allow various types of illumination sources to be selected, installed, and replaced without affecting the integrity of the optical device (10).
