This Spotlight is intended to pass on some nuggets of knowledge about how to go about setting up an optical alignment using a laser and some tricks to use to make life easier.

As a lens performs best for rays close to the optical axis (running through its center) and at small angles, all the individual lenses have to be well aligned with respect to an optical axis.

We’ll discuss the optical and mechanical aspects of my favorite and most general alignment technique – a real workhorse method– and in doing so learn a great deal about the nature of these surfaces.

The aim is to spatially overlap back reflex and laser beam to align the optical element exactly perpendicular to the beam. Small deviations in the position can be seen best at a large distance …

We use a known optic, a catalog off-axis parabola, as a reference to both model in Zemax and to align while tracking the position of the focus in 3 degrees of freedom (DOF) and the tilt of the auto …
