How to assemble a two-lens optical system, a beam combining module, a projector, and a two-lens optical system

摘要

PROBLEM TO BE SOLVED: To realize a method for assembling a two-lens optical system, a beam combining module, a projector, and a two-lens optical system in which the adjustment sensitivity of a lens is improved. A two-lens optical system (100) includes a first lens (1) used for collimation adjustment, which is configured to move only in the optical axis direction of light emitted from a light source, and an optical axis. It includes a second lens (2) used for beam steering, which is configured to move only in two axial directions perpendicular to the direction. [Selection diagram] Fig. 1
