Which Collimation Lens to Choose? A Set of Observations for Your Review

[dkumpula]

Glad that it served some use. I've updated the original post to include DTR's latest single-mode offerings including near-field measurements for those of you who are interested in such information. In the time since I completed this rough comparison, I have started to use acrylic and glass lenses for some of my single mode red builds as I can handle the associated loss when combining the latest single mode reds, blues and greens. I still use DTR's G2s or the 'G2 equivalent' from Aixiz for the latest single mode blues and greens. G2 for max power or when using them in a diode mount like LaserShowParts sells and the Aixiz when combining with DTR's bullet-mounts. (The threading is too tight to use Aixiz lenses in LaserShowPart's mounts.)

Have fun with you build!

Many thanks for the update.
Cheers
PS. Does anyone remember where the list of diodes and specs were stored on PL ?
