I was wondering if a module's lens size effects the visible brightness of a beam...I mean for example a 200mw 650nm red in an Aixiz Module with a glass lens vs a 200mw 650nm red laser in a mini module with a very small fixed "infinity" lens setting? The smaller module would seem to be brighter right in theory because the same amount of photons are packed in a smaller area beam verses a large to small beam comming out of the Aixiz module right? I want to build a really bright 640nm red laser module using a mini brass module with glass lens at 250mw! I saw on listed on a web site...I think it would be alot brighter than a 650nm red at 200mw right due to the power is moer and the nm is lower and aperes brighter to the eye...just one thing different about the 640nm diode it has an emitter size of 60 vs the 650nm 5. is that going to make a difference? Will the 640nm larger emitter allow for burning matches or poping balloons...it is 250mw after all but still a larger emitter.
