I was just wondering if anyone has done any minimum focus point tests with different wavelengths / diodes using the common Aixis module and collimating lens as the focusing device (just for apples to apples comparison)?
I remember people saying how tight the 405s can get. I know my 445 makes lines as small as a ball point pen in plastic when properly focused. Does the 405 go even tighter? what about 650 etc...? Also what about DPSS? my cheap lil green pen already puts needle size holes in things focused out to infinity.
I just want to understand what the limits of focusing are so I have a better understanding of how the different commonly available frequencies compare to each other.
