An autocollimating alignment telescope automatically turns a lamp on in the autocollimating operational mode, and automatically turns the lamp off in the alignment telescope operational mode. The telescope has reticles which are replaceable in the field, as well as eyepiece and lamp housings whose mountings are interchangeable. The telescope also has an assembly for preventing jamming of the traveling lens assembly of the telescope, as well as independently operable coarse and fine adjustments for the traveling lens assembly.

An autocollimating alignment telescope, comprising: (a) an elongated tubular barrel; (b) stationary objective lens means mounted in the barrel; (c) first reticle means mounted in the barrel away from the objective lens means; (d) movable focusing lens means mounted in the barrel away from the objective lens means and forming therewith an optical axis, said focusing lens means being axially movable among a range of alignment positions and a focused collimating position; (e) drive means operatively coupled to the focusing lens means for axially moving the same, in an alignment telescope mode of operation, to a selected one of the alignment positions in which the focusing lens means and the objective lens means focus light from at least one exterior target onto the first reticle means, said drive means being further operative for positioning the focusing lens means in the focused collimating position in an autocollimating mode of operation; (f) energizable light source means mounted on the barrel and operative, when energized, for emitting light in the autocollimating mode of operation; (g) second reticle means mounted on the barrel adjacent the light source means; (h) means for directing light emitted from the energized light source means through the second reticle means, the focusing lens means in the collimating position, and the objective lens means to an exterior light-reflecting target which reflects the emitted light impinging thereon, at least a portion of the light reflected off the light-reflecting target being focused by the objective lens means and the focusing lens means in the collimating position onto the first reticle means in the autocollimating mode of operation; (i) eyepiece means mounted on the barrel, and operative for enabling a viewer to view the light focused on the first reticle means in either mode of operation; and (j) automatic switching means operatively coupled to the light source means and the focusing lens means for automatically energizing the light source means when the focusing lens means is moved by the drive means to the collimating position, and for automatically deenergizing the light source means when the focusing lens means is moved by the drive means to any one of the alignment positions, whereby the emitted light is automatically lit during the autocollimating mode of operation and is automatically extinguished during the alignment telescope mode of operation.
