Stylus Assembly Alignment with Lasers

[[Is...]]

Has anyone used lasers or range finders to gauge the squareness or straightness of a stylus assembly? An example would be a star probe and checking the straightness of the #2 and 4 tips, distances to them in X axis to verify if they are skewed. We occasionally have issue where a stylus is bumped or somehow otherwise gets mis-aligned.
We are looking for a quick way to verify the squareness/alignment of the stylus to the Y or X axis.

I understand this information is given in the stylus information page with exact measurements to each probe center, our management is looking for something quicker that can be attached to the cmm table and left set up. I.e. lasers set up on the left side pointing back across the X axis of the table and into the shroud opposite.
I also figure if this has been done then the lasers required to get the desired ±0.001mm accuracy would be expensive, i.e. more than $1-2k.

The X/Y values from stylus qualifications can be helpful.
Also we typically square up to mechanically tooling/blocks using the bolt holes.

Quicker than a probe requalification, but accurate to a micron?
...seems like an unrealistically high bar (unless I am misunderstanding).

Zeiss sells an overpriced (imo) stylus setting tool.
For most of my measurement tasks, I just do a visual to a circle w/ crosshairs, on a piece of paper. lol.
If there is a tight clearance, then I use tooling blocks, and a sine plate (for angles)

You can see the offset values in the "Probing system qualification" menu.
Due to the build of Styli and components I generally do not worry if they are offset around ±.008 (Inch).
From this you have:
Stylus Length
Stylus diameter
Shank Diameter
For example:
A 2mm ruby with a 40mm build in length yields about 35mm of useable length in a perfect world.
The standard shank diameter is 1.5mm.
A little math and you have a side clearance of about .00984 (Inch) (Assuming nominal values of Shank Dia and Ruby Dia).
This means I can use that stylus to a depth of about 35mm although it could be angled off by a maximum of ±.008 (Inch) and I wont shank.
