For what it is, it is pretty amazing. Made a hologram in 20 minutes from opening the box to looking at it in laser light (transmission hologram)
If Hey, that’s just a picture of a red car in red lightIf it is, then how am I putting my finger in it.
I exposed until I started seeing interference fringes. Those meant that something had sagged or moved, and I would be ruing my exposure if there was any photo-polymer left to convert.
Two attempts at reflection holograms were partial fails.
For what it is and what it costs, not bad. $130 bought a laser, battery pack, 20 plates of film, acrylic plastic kit for holding everything together.
Acrylic is not the most thermally stable thing, but hey, my first exposure worked. I will be adding my own improvements, but I got my money’s worth.
I tried a reflection hologram again with a DPSS laser pointer. Astounding.
