O-Like 405nm 400mw Blu-ray

I recently received my second one of these, and it has a problem that the first one does not have.

The focusing mechanism is so tight and hard to turn that it just about takes the skin off my fingers to adjust the focus a little bit. It is very annoying, and makes the focusing almost unusable.

Does anyone know what might be causing this, and how to fix it?

I tried to remove the subassembly containing the lens and the lens holder and the inner part of the focusing threads, so that I could examine both sets of threads. However, when I twisted the lens holder all the way out it hits a hard "stop", and I cannot turn it any further or remove it.

I had this same issue. I was taking the lens assembly apart an ran the focusing ring the whole way out to the stop. Then I wrapped a rag around the focus ring to avoid damaging it and used pliers to unscrew the ring. Next I put the rag around the threads and with the pliers ran the lens assembly out a little further till it was really tight, then put the focus ring back on and run it back down (may have to use the rag and pliers). This crushes that O-ring and makes the focusing easier.

You may jeopardize the waterproofing but I would rather have a focusable laser than a waterproof one.

Also the lens assembly is removed from the host buy running it through the opposite way. Not sure if that makes sense or not. But you need a tiny spanner wrench...

Thank you very much.

(I wonder how you could possibly have figured out how to do this, but figure it out you did).

This worked well. This troublesome second unit is still noticeably tighter than my favorite first unit, but at least now it is usable and OK to work with.

While I was at it, with the ring forced off, I punched out the "waterproofing" glass pane from the front of the focusing ring. Subjectively, I think the dot looks better now. But, one cannot trust my subjective impressions.

I did the same thing to the waterproof lens.

And I pretty much accidentally figured this out. Glad I could help.
 
For the foam insert around the unsupported -ve spring terminal issue, actually one can just cut out some LPDE foam, punch a hole in the middle, and slot it in. Works the same. Need to do a couple of times to get the correct thickness, but any foam helps better than no foam.

Shouldn't take more than 15 mins total to do even for a couple of times to get it perfectly right. :)

Then again, even my cheapo usd33 shipped SD-302 greenie comes with the foam support around the -ve spring.....
 
I found that my 405mW O-like is the best burner I have in the bunch. Between the wavelength,and the ability to focus a very tight beam, it outperforms even my 1W 445nm. Up close (less then 2') the 405 and 445 are fairly close in burning capabilities, but at a distance of 25-30ft, the 405 wins hands down. I am not impressed with the 445 multi-mode diodes that are out there.
 
Thanks for this review. I have one on order and after reading this emailed o-like to verify that the spring is supported before shipping. Posts like these are really helpful.
 
Unless they have recently revised the item, or they do a custom job for you, the spring is not supported.

The spring is very easy to get to, however, so it would not be hard to do your own foam support. I have on my "to do" list to do this with the 2 units I own.
 
just placed a order for the 405nm but before i placed my order i spoke with susie via email ,,,after a few emails she said there will be support foam around the spring,,,i should have it in about ten days ,i do have a lpm and will post a video lmp testing

i placed the order for the 405nm 400mw and the 532nm 400mw ,,after reading some more posts i cancled the order for the 405nm 400mw,,o-like refunded me the money for the 405nm laser but still shipped it to me for free by mistake,,,i sent o-like a email waiting for reply

Mine does not have the foam....actually after multiple inserts of the 18650, the board/spring is not crooked. Not a big deal, just make sure the board/spring is centered in the tube.
 
was wondering if anyone has tested the 405nm 400mw laser from o-like with and without the waterproof lens :thinking::thinking:

mine is peeking at 347 with the water proof lens
