Oh. Well, given that I already have that diode, and it's an OSRAM after all, I feel like a big dolt for ordering an OSRAM from o-like to compare. It looks like I'll be comparing it to itself. Btw, the OSRAM I harvested from a pico projector some time back, lased fairly high. Above 455 by my best efforts to estimate.
1) The OP referenced ebay, but I see now that this was actually Rayfoss as well. Is there a current source for the Opnext?
2) Do you know of any 3.8mm housings? My previous 3.8mm housings have had to be custom made. Is there an Aixiz-like 3.8 housing yet?
