Just as electronic breadboards often rely on integrated circuits (notably OpAmps), external power, and test equipment, optical tables also benefit from more than simple packaged lenses. Here we document the optical tools available at HacDC, many of which are self-made.

Tools

Complex drop-in optical systems, ready to create or analyze complex light fields.

WideBeam Collimated Light Source

A wide beam of high-intensity collimated light is useful for manually checking the results of complicated optical beampaths.

DLP Light Structuring

HacDC has access to some DLP projectors, absent working light sources. These can be used as re-configurable image sources and high-speed light gates.

Fixtures

Generic mounting hardware.

Tilt and Roll Platform

Even if we could afford them, commercial systems are too expensive to permanently dedicate to completed projects (~$500). Instead, we will 3D print or laser-cut a screw-adjusted spring-loaded platform, much the same as the adjustable bed used by many 3D printers.

Adapters

Mounts made to mount optical rails and cages to the table.

Standards

External

Standards set for us by manufacturers.

Internal

Standards we have elected to follow from the above, or have established ourselves, as we build our own tooling.
