Default Massive Prism@Awesome Price !

Hello people *
I would like to share with you some interesting stuff such as non equilateral prism that allow you to make double total internal reflection, so the laser beam is send back to the emmiter ... there are many other application, for example to play with some light path, or also create rainbow (not tested because no sun at now)
Here it is some picture, sorry for the poor quality, i don"t have my tripod to make good photo *:-/, and my beam is only at 50mW, so we can't see the beam very well, but in reality, it's very bright :

Classic refraction

Double total internal reflection


(+fog)




I found them on ebay(14.5 cm along the hypotenuse and almost 3.8cm long):
http://stores.ebay.com/Optical-Supply
i bought the "chipped" one (5 of them)for 33$, im really surprised of the quality, better than expected, the chips are very tinier and don't bother me, for the price, it's really a big deal !
+ the seller is very friendly and the prism are insanely packaged, don't need to say that i'm very satisfied !
I'm very happy to have found this seller *

Oh.. I would sure love a set of prisms like that, and the price is very good indeed. Anyone feeling generous this holiday season?

Side question: Do you work for Google?
