If you have both diodes you could use a G2 lens in each and measure the focused bar at the longest distance possible, at 20 meters you will have a large bar, something like 30mm x 150mm with a NDB7875.

If it is 14um wide, which axis, that's what I'd like to find and what the size of the other axis is.
