I was having a particularly long day after which I just wanted to take a rest...but somehow I ended up writing this design. It's a nice barion oval with surprisingly good performance, and even though I hate ovals I don't dislike this design. Works in materials from beryl to rutile (RI = 1.58 - 2.62) with no changes, but I prefer it in tourmaline.
