Default Markerlights

How exactly do these work? Are they merely IR beams, or something different?

I think they are modeled after the laser-guided bombs that we can drop from airplanes, but this is a science fantasy game, so they basically work on whatever principles you want them to. If you think, as I'm sure we all do, that it's a little dart that unfolds into a giant neon-green bullseye with the words "shoot me" on it, then that's what happens!!!

Well, I'm wondering because if they are just IR beams, then why the hell can't troops with IR scopes and sights not see the little red beam coming from the bushes?

There's a bit in the original Codex about Markerlights having a "barely-visible" mark... my guess is some kind of optical beam (okay, flashlight) with special properties that makes the 'mark' light up like a disco ball for anyone with specifically calibrated sensors (i.e. other Tau forces).

The markerlight makes a barely-visible spot on its target, so it must use visible rather than infrared light. If markerlights are lasers, like comparable real-world target designators, the spot will show up perfectly if you filter out everything except the specific frequency at which the laser operates. (That'd be what Dra'Tuisich-Novae was saying about sensor calibration. For extra security, depending on the type of laser, you could tweak the frequency slightly before each battle so that your opponent couldn't do the same thing.)

That doesn't mean that using a markerlight will give one's position away like Legio Mortis suggests. Look at laser pointers - they make a clearly visible mark, but you can't see their beam unless it's passing through something like a cloud of chalk dust. If a markerlight spot is barely visible, presumably the beam itself is even fainter.

I am inclined to think they are a little more complicated than the original codex described. The mark they produce is apparently distinctive enough for Imperial troops to recognize as something unique, so I doubt it is just a faint red dot. Moreover, if it was just a laser designator, there would be no reason for the rules to work as they do, with the designator only useable by one target.

I am more inclined to think that the actual data for the Markerlight is being fed from the weapon. So it is not that the firing unit or Seeker Missile is locking on to the little red dot, but rather that they are being fed a direct stream of targetting data from the Markerlight itself, which is only using the laser as a range finder of sorts.

Imo, a markerlight is probably a visible laser beam, likely green (more visible on a wide variety of targets than red), that provides location and range information which is simultaneously uploaded to the Tau Battlenet.

In essence, the 'light includes a laser 'mark', computer, communications uplink and telemetry software; providing a complete battlefield targeting package.

So then, someone with appropriate vision gear could see the beam and where it was coming from?

The beam is probably polarised/masked in a particular way that you need specialised visual gear (read: Tau Optics) to see it properly. All you could/should see with standard gear is the 'dot'. The beam would be invisible unless it passed through particulate matter (smoke, fog, etc).

If it was low intensity, having optical gear probably wouldn't help very much. Laser beams don't really emit light. You can only "see" them when photons are diffracted by particles in the air at an angle that happens to hit your eyes. Of course, if the Pathfinder shined the Markerlight directly into your eyes, it would be pretty obvious where it was coming from. I imagine they are trained not to do that. Basically, Pathfinders should be thought of as snipers but without the actual shot. You don't have the luxury of standing around in the open looking for the source of the marks.
