[time-nuts] Wide angle light into ST connector/multimode fiber?

[lstoskopf at cox.net]

 I want to get light from a wide angle (30 degrees or so) into a multimode fiber cable to feed a fast MF466 photodiode for short distance sensing.  That fiber is really small to focus on.  Anyone done this...looking at a reflection of a red laser diode  flashing dot a couple of meters away through fiber?
