Nice little cubic beamsplitter prism. (Get it?) 12 x 11 x 10mm, it's painted black on (3) sides. Low transmission-about 70/30 or 80/20-but it'll be fine for classroom demos, experimentation, or perhaps souping up your fancy laser device.

42819 BEAM SPLITTER PRISM |
Optical grade unsilvered glass prism from Uncle's WWII tank periscopes. This one is 2-1/8" on the hypotenuse, 5-3/4" long, and 1-1/2" on each leg. They may come with small non-interfering chips or surface scratches. Great for classroom experiments or for art projects. These are a true surplus find and they will not last forever so get yours today!

3538 MINI-MONSTER PRISM |
Polished glass equilateral prisms. Equilateral because each edge of the end is the same length, 32mm. Thus, as all you geometry students know, each of the angles is also the same, 60 degrees. These are school grade and are fine for decorative and demonstration. They do a nice job of diffracting light to produce a nice rainbow-like spectrum, but are definitely not up to instrumentation standards. The missing dimension, length, is shown below.

From Sun Catcher®, a transparent prismatic sheet, roughly 4-1/4" x 5-1/4", inside an oval frame, roughly 10-3/4" x 8-1/4" with a variety of motifs. We'll pick (1) of (3) diffraction patterns inside (1) of (6) heavy cardboard frames: undersea critters, fairyland, jungle life, a wizard, dolphins or a garden with butterflies and a hummingbird. It will "transform light into an explosion of multiple hues," and who doesn't like that? Comes with a suction cup to mount in your window, and if you're a minimalist you could cut the cool prism out of its frame and we wouldn't tell a soul.

Dull outlook? Dreary prospects? Put a little edge on things with this pair of cardboard (think movie 3-D) Prizm® glasses that have (1) clear frame and (1) with slight diffracting properties to give brightly colored pictures a pop and a semi-, sort-of, 3-D effect. Interesting for classroom demonstrations. They measure 5-3/4" across with approx 5" temples. And yes, we know how to spell prism; blame the manufacturer.

WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Through our little black-plastic right-angle viewer. It's a 1-1/4" x 1-1/4" hexagon, and Paul says that if you buy (2) you can see eye-to-eye with yourself, which is a little spooky. Great for a little light spying on the street, and if you find a way to stick it over the lens of a small digital camera, you'll get great candid shots.
