Why have i not seen laser pointers like this? (laser pointer Idea)

More difficult to implement than other multi-diode handhelds IMO, I like having all my batteries in one place, all my drivers in one place ect.

Plus, it's hard to point a tradition handheld in the wrong place, I imagine it would be fairly easy to shoot your eye out with this

Can you link me? I remember seeing them for that stuff was really bulky.

This what you're looking for?

It isn't *that* bulky Need a good amount of space for the alignment anyway.

Knife edging can be done with mirrored right angle prisms. As seen in this Thorlabs product.

YIKES !!! This Thor Right Angle prism would require a NEAR perfect entrance of each beam into the prism...I imagine NOT an easy thing to do in a lab setting....let alone in a hand held format.....Knife edging in a hand held has been achieved....both by JLSE and myself !!! It is a pain....as is ANY beam combining operation...in a hand held format....It IS DOABLE....but very challenging....but...that's the fun !!
