SOLD I have for sale 2 WL Spyder III Arctic 445nm lasers for $200 each, plus shipping.
SOLD #1 - 795mW
SOLD #2 - 750mW
I purchased these from another member here who was less than satisfied with his Wicked Lasers experience. If I had received what he did with my first Arctic, I would have been just as disappointed. There were several things wrong with them (no surprises, eh?)
One was producing an ~6 inch "line" at 30 feet. The other was showing some sort of double spot with "wings." In addition one of the "high powered" lenses was threaded on stock that was too small in diameter. That lens simply slipped in and out of the front of the laser!
My original intention was to simply tear them apart and build them back custom and reliably high powered. After I evaluated them, I realized that I could "tune them up" so that a couple of people could have a great laser at a lower price. I decided to go this route instead. I figure eventually, I will be able to purchase a host from someone who's Arctic has died.
So I went to work. First I had to clean back all of that thermal grease that WL seems to think is doing the laser some good up front there. It is now back far enough that it no longer contaminates the threads of the aperture caps or the focusing lenses.
I pulled both focusing lenses to clean them and to get them re-focused correctly. They were both "dirty." However, the one that was producing the "double with wings" was doing so because the lens was broken! I replaced that lens with an AixiZ glass lens.
Once I got the focusing lenses out, I was able to examine the fronts of the diodes. BOTH of them had crud on their windows. I don't know if it was thermal grease or just greasy fingerprints. They both cleaned up fine with acetone and a microfiber cloth.
I reinstalled the focusing lenses using a bit of teflon tape. With everything repaired, clean, and adjustable now, I got them both focused nicely. Here they are at ~30 feet.
I still had the problem of the one lens that was threaded at too small a diameter to work, but further examination and thought made the decision easy for me. You don't really want that "high powered" lens in there any way! As has been noted by other reviewers, the glass is NOT AR coated. It is reflecting >100mW right back into the lens and toward the diode.
I took the "training" lenses and removed the ND filter glass (also not AR coated) and re-installed them without any glass. The fronts now look like this
In addition to allowing the full power of the diode to come out, this also leaves the focusing lenses accessible. I have a tool that I will recommend that whoever gets these buy as well. The tool is from Microtek.
Microtek Illumination - Aixiz Module Lens Adjusting Tool
The tool fits right through the aperture cap and allows you to focus your Arctic. You can focus it up close for burning or to infinity for star pointing or beam work. The laser beam shines through the middle of the tool so you can focus it while the laser is on It is not as convenient as a focus ring, but it preserves the look of the front of the Arctic completely
I think that this is going to be a recommended mod for all the Arctics. Toss the "high powered" lens. Remove the ND filter from the "training" lens. And get one of these focusing tools from Microtek. (I am not affiliated with nor do I gain any income from Microtek)
Here are the LPM shots for your viewing pleasure.
The lasers come with the battery and charger. They do not come with goggles.
Once again, these are offered here at $200, plus shipping (your choice) each
Peace,
dave
