MAUGC Uranium Glass Cube

The Uranium Glass Cube will be a great tool for proper positioning of the cube for transmitted diascopic illumination demonstration /instructional tool for educators to show difference of Phase Contrast annuli Ph1, Ph2, Ph3 , Darkfield –Paraboloid or Cardiod type illumination and out of alignment lamp sources can be visually seen with the MAUGC Uranium Glass Cube.

The Uranium Glass Cube will be a great tool for proper positioning of the cube for transmitted diascopic illumination demonstration /instructional tool for educators to show difference of phase annuli Ph1, Ph2, Ph3 , Darkfield –stop or Cardiod type, working aperture concepts, out of alignment lamp sources can be visually.

Note: The proper positioning of the cube for transmitted, diascopic illumination is with the matted surface facing upward.

Suggested Applications

•Demonstration of angular aperture provided by condenser
•Demonstration of phase annuli, varying in size with magnification
•Demonstration of increased angular aperture with immersion oil between the condenser top lens and the cube base
•Demonstration of oblique illumination
•With turret condenser out of position
•with de-centered aperture diaphragm or oblique insert
•with card or hand under the condenser
•Demonstration of both “dry” and immersion darkfield condensers
•Demonstration of the difference in angular apertures between an Abbe phase condenser set at the largest annulus and a darkfield condenser (either paraboloid or cardioid)
•Demonstration of noise permitted with either brightfield or phase contrast and a wide open field diaphragm (can be shown dynamically)
•Demonstration of the differences in base collection systems, with varying angular apertures and distinctness of angular apertures produced
•Demonstration of the effect(s) of misaligned lamps within the angular aperture
•Demonstration of the effect(s) produced with varying collection of the lamp – varying the collector, varying the position of the lamphouse in relation to a fixed collector, or choosing different selections within a Barer-Weinstein collection assembly
•Demonstration of incident illumination (the cube should be inverted from the Note above) – this can be used for brightfield and darkfield techniques. Turning the cube’s matted surface to the side allows for matching the base illumination cone with that of the incident cone. As well, different objectives (“condensers”, functionally at this point) demonstrate different angular apertures with the cube.
