OK-- the dishwasher is finished the dry cycle so out comes my biggest spoon-
first you could not be more wrong about the vets here or our attitude towards you and other newcomers-
without new members we will not be as healthy as a forum.
You didn't find what you sought because there prolly is NO info in the data base about the use of ND filter to lower lasers power enough to be eye safe. Most here wil prolly say there is no laser that is 'good' for the eyes-
AT first you said you wanted to take yr laser to a concert- that is still and will always be a bad idea-
BUT at a rave-
you would be OKay as long as nobody gets pissed about being face scanned... and that, my friend, may mean telling a few strangers( even foxy chicks) that 'NO --sorry... but I cannot let you 'play' with my laser'-- when you hand it over to anybody you are taking a huge risk with some innocent persons eyesight-
- they will not understand and prolly think you are a prick but you must stand your ground. You should *never* let anyone run off and cause you to lose any/all control over what they are doing plus once one person gets to handle it many more will also want to do the same and that can become a bad idea very fast.
about the diff. grates -- yes.. if a 100 mW laser goes thru a grating that make 100 beams they will be less than 1 mW each and at a rave keeping a grating one your laser may be a very smart move.
while we try to over-stress safe use and having proper eye ware the truth is this- once you are *EXPERIENCED*- you know where the safe zones(90% of the time) are and then the main reason for eye ware will be when taking measurements for divergance- doing LPM tests, aligment and set up. most of the time our glasses are around our necks or on our foreheads. IF you are very careful you can use your laser around others without them needing eyeware. But you cannot become experienced instantly- aint gonna happen.
and the 'show' is better without goggles.
trip glasses make the show even better.
Your best bet for a rave may be some cheap pointers- nothing you will lose sleep over if it gets taken from you. you can get gratings for them too.
stay hydrated and never take any pills from unknown sellers.--
hope you enjoy your rave
