High-contrast soap film magnification device

摘要

A surfactant film viewing apparatus having a chassis, film wand, and film wand positioning means. The chassis is opaque and has a magnifying lens and a light aperture to allow ambient light into the interior of the chassis. The chassis, with the exception of the light aperture and the magnifying lens, forms an substantially closed surface. The film wand has a hoop suitable for supporting a surfactant film across its span. The apparatus includes a means for positioning of said hoop in said interior of said chassis such that the position of said hoop relative to the magnifying lens is stable but manually adjustable so the surfactant film can be positioned for viewing by said magnifying lens. The apparatus may include a reservoir for the surfactant/water mixture, and the means for positioning may also include a means for dipping the hoop in the surfactant/water mixture. In an alternate embodiment the wand has multiple hoops each of which is capable of supporting a surfactant film, rotation of the wand bringing the surfactant films sequentially into view.

1. A surfactant film viewing apparatus, comprising:
an opaque chassis having a light aperture to allow ambient light into the interior of said chassis and a lens aperture into which is mounted a magnifying lens, said chassis, with the exception of said light aperture and said lens aperture, being a substantially closed surface; a film wand having a hoop for supporting a surfactant film across its span; and a means for positioning of said hoop in said interior of said chassis such that a position of said hoop relative to said magnifying lens is stable but adjustable by application of manual force so said surfactant film can be positioned for viewing under magnification by said magnifying lens.
