Though the tiny lights of the Coachella Valley set the scale for the mighty size of the San Jacinto Mountains, even that range is dwarfed by the mighty scope and expanse of the sunset.

A childhood spent with a bedroom window facing the train tracks built a skill for identifying train engine paint jobs, but the intervening years of mergers and the geographical distance between Illinois and California have diminished the intense recognition that would have had me swear that black, orange, and yellow meant a BNSF engine.
I recently moved into a new office with a huge, boring, blank wall totally ready for a huge, interesting, dramatic landscape. That naturally meant returning to one of my favorite land/cityscapes, this view of Oakland, Berkeley, San Francisco, and Marin from sabbatical in 2017. For an image I expect to stare at for years to come, I really pulled out the stops in terms of producing the best possible image. Click through to Flickr to zoom in and get all of the details!
For all of the fancy-looking holders and posts and hardware, an optical table is ultimately designed to put specific optics in front of the laser beam as it travels to generate a desired effect. This view of the space leading to our detector shows how many parts can accrue in pursuit of a given goal.
Retroreflectors are used in optics to send a beam of light back from whence it came. While this can sometimes involve laborious alignment of adjustable mirrors, these custom-built “zero degrees of freedom” mounts hold the high-reflector mirrors against perfect-90º prisms to guarantee the correct geometry.
