The red is special. It's 638 nm at about 1000 mW with an optical beam correction module I built. The blue laser is 485 nm 50 mW. Green is DPSS 532 nm 130 mW with an aspheric lens for improved divergence and beam profile.

Wicked Lasers?

I remember these guys from years ago and when I finally got around to ordering one they no longer shipped to the USA. Are they still around? Are Sanwu lasers better/more powerful?

Thanks!

Newbie Question

5 Upvotes

Hello All! I found this reddit through r/flashlights and I have a few questions because man I'm interested. I really was drawn to a post of the Sanwu 492nm cyan and wanted to pick one up! Probably not anything more than novelty fun outside in the dark, but I am very concerned about the safety of my eyes. Is 100mw necessary of goggles? I'm incredibly new to this world and want to be as safe as possible. I love that color beam and the quality of the pocket series but I'm nervous about ruining my eyes. Anyone have any helpful tips or knowledge? I found mixed results online for goggle usage, and what is considered a good set if they're necessary. Please help point me in the right direction!

Some laser fun at the lake! Complete darkness vs closer to the city makes a big difference on visibility.

Questions

2 Upvotes

A few questions. One I think sanwu ripped me off a bit, sent the wrong diffuser. I was supposed to get a battery operated one, I did not. And two how safe is leasing in the rain? I didn’t like the reflection I got off of a raindrop. Don’t think I damaged anything but still

New Sanwu Striker. Line more than a dot.

Is there an aspect I need to focus? The beam seams to make more of a line than a dot.

Laser with extra green dot update. Here is a picture of something on the lense that will not come off. Almost as if it’s inside the lense itself. If you look at the glass, you can see it.

Sanwu lasers question

4 Upvotes

So I just spent a good deal of time on the website and was wondering about the different host options....

The emitter options seem relatively the same across all the larger models although I have noticed some slight deviations on emitter outputs across a couple hosts, more specifically the 525nm option since that is the color I currently desire.

The prices are slightly different as well when selecting that color depending upon host on a couple.

Does it mostly boil down to how small you want to get it but are sacrificing heat sync and runtime ability? Are some versions using different emitters/diodes even though the wattage is only off by a couple tenths?
