It looks to be a 1.5mW laser. On that same page they list some phototransistors etc that will work with it, so I would imagine you could use it as a focused range finder of sorts.
Now lets get back to the part that it is a laser, and one that is hitting on the infrared spectrum. A 5mW red laser (around 620nm spectrum) has very little IR bleed out but can still manage to cause eye damage (blind spots). The more IR a laser gives out, the more you need protective lenses to be around it when in use. Even though this is a 1.5mW laser, it is high enough in the spectrum that it would not make for a good "being around people" robotic sensor.
