Optical system alignment can be especially challenging and infuriating, even for a “simple” system. This is due to two main challenges – the inability to physically touch/probe the optical axis (the light passing through the optical components), and the tolerances required to achieve good optical performance (may be order(s) of magnitude tighter than mechanical tolerances. This course will provide optical engineers and technicians the tools for aligning typical optical systems. These tools will include theory, equipment, and the tricks of trade.
