An optical assembly with having a dust seal incorporated therein is disclosed. The optical assembly has a first portion and a second portion separated by a space wherein at least one optical component is located in the space. The dust seal may be a section of polyolefin tubing or heat shrink tubing that encompasses the space. The dust seal is placed adjacent a section of the first portion and a section of the second portion. Heat is then applied to the dust seal, which causes it to shrink and, thus, conform to the first portion and the second portion. The conforming dust seal seals the optical assembly and prevents contaminants from interfering with the optical components located in the space.
