NUGM01T-520nm

[LaNeK779]

assuming that one has no 520nm diode installed, what would be the best to go for? nug01t or ndg7475 ?

if power is close, which yields the best beam specs and what are the recommended optics? G2 and 4x cyls as mentioned above?
in general i prefer a cleaner beam than a couple hundred mw of power

an image of the corrected spots would be greatly appreciated (trying to get myself up to speed again)

Speaking with Dave on the telephonic communicator earlier today, he was saying the G2 provides the lowest losses, yet the three piece glass lens clips the wings so provides a tidier beam at the cost of higher loss. I am going the G2 path with spacial filtering as I have now with M140 diode.

so, what is your source of lenses for the telescope?

I think to made soemthing on this diode. Maybe you know who is most brightness? DPSS 532nm or this diode?. I know that green is the best for human eye but how about this small different in nm?. I read that at day the best is ~555nm, but at night it move to 510 nm.
In most laser show is at night... So?

I wish there was more data on this diode.

Like why would you want to remove the stock lens? Is it not a collimator? Is it a collimator with worse specs than G2? I thought G2 was AR coated for the blue spectrum only. WHat is the % of power loss with G2?

What about beam profile? To compare to the NDG7475 (beam profile of the latter is available at DTRs page). I'd like to have a general idea at least on what beam profile I'll end up with after a prism pair.
