Yes more or less.Hello,
at the DTR side, the NDB 7875 has a much smaller dot than the NDB 7A75. Doesn`t that mean, that the divergence is better?
I have this laser and mine does 3.8 watts+. I bought the beam expander too for use with my 1 watt 520nm PLE-Pros.Yep, if you want 4 watts or more, the choices for acceptable divergence are reduced and the choices worse, that is, unless you use a larger lens with a longer focal length, or put a beam expander on it. To have decent divergence at the higher power levels, either have Lifetime or Trinh make a custom pointer, or buy a JetLasers pointer, they have inexpensive beam expanders available.
Screen shot of JL price with beam expander included:
You would need to check on this, but I believe the divergence would be less than .25 mRad with their BE on it.
If you are going to buy a JL, I'd recommend their 465 nm PLE-Pro instead, although 3.5 watts, it is on sale right now and can also have low divergence with a beam expander you can buy with it as an option, below is the sale price right now with the BE:
3.5 watts of 462-465 nm will be brighter to the eye than four watts of 445 nm!
