Throughout my career in the industry I have collected dozens of custom lenses, mirrors, fiber optics and prisms. They don't make sense until you light them. The laser does its job. Some people like model trains. I set up my little Garage-a-Tronics so that the prisms and lenses shoot beams of light around the otherwise hidden optics. I usually use a red laser pointer to light them up. This table-ready laser holder ticks all the boxes. I'm pushing the limits of the red laser. The green laser follows the same configuration and achieves more optics. More fun than expected.
