This is an inaccurate version copied from an original like this one: http://www.aps.org/publications/apsnews/200306/ligo.cfm The beam-splitter should be drawn at 45 degrees!

Indeed a terrible copy of a very old file, the beam should reflect off the front of the beam-splitter, but instead it appears from behind. There are much better illustrations available today. — Preceding unsigned comment was added by 2001:982:5820:1:3C9B:79A1:3EFF:E059 (talk) 15:27, 5 May 2020 (UTC)[reply]
