Amlong Crystal 8 inch Optical Glass Triangular Prism for Teaching Light Spectrum Physics and Photo Photography Prism, 200mm

Good optical quality glass & effectively diffracts sunlight into a sharply define rainbow.

Surpringly good quality; even the box it comes in is nice. Size is as advertised, and it has a very nice weighty feel. I tested some LEDs behind it, and it lights up admirably. Very pleased.

It's a great and unique gift to give someone. They will be a little baffled but then pleasantly surprised.

I use it a lot for flare effect as well as for framing, hiding unwanted objects or subjects. I used to use smaller 7"-version with my 85 mm f/1.2 and 35 mm f/1.4. But once I got 28-70 mm f/2.0 I realized I need bigger version of such prism because front lens is much much wider. The whole set is heavier now but works like a charm.

I have rather small hands and wish that it was easier to hold but overall it is a worthwhile investment.

Very nice looking at the outside colors

Very high quality prism. I can't dock any stars as it is a very nice clear prism and it came in a very nice package. However, I wanted this for the rainbow effect in sunlight. Unfortunately this prism, being an equilateral prism, does not work as well for this effect as right angle prisms. It's still a keeper but I'll just have to find something else to do with this prism.

I find rainbows from prisms very uplifting, and I own quite a few. This one stood out because the rainbows it cast are so very large. I love it!!

Produto excelente. Chegou dentro do prazo.

Large prism, easy to handle.

Great for teacher demonstrations of prism refraction. Nice ornament too.
