Online mRad divergence calculator, measure output beam diameter and then spot diameter at a distance, input numbers: https://www.laserworld.com/en/laserw...ivergence.html
Beam divergence calculator - you can clearly see the importance if the distance is increased: https://www.laserworld.com/en/laserw...alculator.html
Online Relative Brightness Calculator: https://slickscreen.github.io/laser-tools/brightness
Pulsed Laser Peak Power Calculator (YAG etc.): https://www.ophiropt.com/laser--meas...wer-calculator
Cheap way to measure wavelength: https://tinyurl.com/Measuring-wavelength-cheap
If building a low divergence fat beam pointer, what diameter lens do you need for a given distance from your diode? Find the angle of radiation for the raw output of the diode and determine the size needed at a given FL: http://www.1728.org/angsize.htm

Emergence Theory ????????????? WHoooooaaaaaaa ????? OK....Sure !!!!
Something VERY strange is indeed at the Heart of Reality !!!!!!!!!!!! Something SO strange....I am NOT SURE...I wanna know !!! BUT...If it includes me seeing my dog Terra again....I am ALL for it....ALTHOUGH...I gotta tell ....Our 7 month old Wheaten Terrier....Crochie Doodle...IS JUST A GIFT FROM GOD ! He is such a goofy and sweet dog.....WAY to smart for his own good !!! Again....I am really LUCKY !!!!! See attached pic of Mr. Doodle !!!Comment

Well, whether true or not, I like the theory but I am too woo-woo, I must admit that. Hope springs eternal. Sorry for your loss, now you have me wanting a dog too, they are wonderful, no judgement just friendship.Comment
