It seems like you can choose from a variety of emiters/wavelengths for any given body/chassis style. So whats the real difference between all the different series (guardian, challenger, challenger 2, striker etc.)? Just the battery they use?

The cooldown/duty cycle also varies between the different body styles, but isnt that more dependent on the emitter or is it also dependent on the heat dissapation of the body?

Also they list a range of beam divergences for their difference frequencies. But is there a reference somewhere as to what the specific divergence is for a specific frequency?

Thanks!

Battery capacity, size, style, thermal properties.

Both, a more powerful laser will also produce more waste heat, whilst a larger host will be able to absorb more heat thus run longer or support a more powerful diode.

The difference in divergence is a result of the different laser diodes used. It's not wavelength dependent.

Thanks!

does Sanwu publish any specs for specific wavelength/diodes? or are they third party and you can look at spec sheets of the manufacturer?

Diodes are all third party, specs will vary based on not just diode selection but lens selection too. Most noticeable will be beam diameter/divergence.

You'd need to ask Sanwu to provide these details, or check here to see if someone has the particular combination you're looking for.

I see.

Do certain colors burn better than others at distance? I know 555/532nm (green) is most visible to the human eye, but just because its the most visible, doesnt mean its the most "powerful" right? Like 1W of violet, IR, UV, blue and red are all equal right?

A watt is a watt, but for burning at distance a single mode diode or DPSS will work best. The single mode 405 nm diodes (BDR-209) have great divergence and burn well out to tens of feet.

single mode as in a fixed output level?

No, I'm talking about the nature of the beam coming out of the diode. Try using the search button and look for

single-mode and multi-mode laser diodes
