Follow-up. I received my beam expander and protective glasses last Thursday. It had to be re-shipped, but Sanwu did re-ship after it became evident that the missing package never made it to me. The beam expander is also nicely made. I've been playing with it, and to be honest, I'm not really sure how to best use it. I thought I'd be able to use it to focus the beam into an even smaller pinpoint, but it does as its name implies - widens out the beam.
Skans did you mention that the beam expander was for the Spiker ? If you didn't you will get it without the adapter and then it will not adjust,i have done that with mine and now awaiting the adapter to arrive ,then it should narrow the beam... Cheers Tassie
Without the adapter you have to focus all the way out to screw it into the Spiker so you cant focus all the way back in which means you will have the wide beam, please correct me if i am wrong but i think that is the problem i will know for sure when my adapter arrives and i can then see the difference.
Well my Spiker adapter arrived today and yes i was right you can narrow the beam to a small dot and impressively will burn cardboard at 35 feet. WOW is all i can say,well done Sanwu you have a very well made and powerful laser there.
I can honestly recommend Sanwu and the Spiker to anyone wanting to buy a high level laser.. Thank you Sanwu expensive but worth the money..
I've been away for a few weeks. I did not order the adapter, didn't know I needed it. Yes, without the adapter, the beam expander is fairly useless on the Spiker. I was going to try and play with it a bit more to get it to work, but, honestly, I was afraid of burning my hand. Ok, so I'm going to go on Sanwu's website and see about ordering this adapter. The confusing thing is that the beam expander will screw into the Spiker without an adapter, but you have to make it so out-of-focus to get it to thread.
I looked briefly on Sanwu's website, but can't find any reference to the adaptor for the beam exapnder - where did you see it? .................Nevermind, I found it...Duh! For anyone ordering the Spiker with Beam Exapnder - adding the adaptor is not obvious. I will need to contact Sanwu and see if they can sell me just the adaptor - there's no option on their website to do this.
I just put my order in for the Adapter and the Beam expander. question, Is the Adapter for the Beam Expander? or do you just use the Adaptor alone on the Spiker.....? My Spiker has been shipped.. just waiting on how everything is pieced together.
Skans, do you still have that problem with the laser dimming? When I was reading that I thought about how Podo mentioned his drivers lower the current to the diode over time to prevent overheating, but I haven't noticed it in my Silver Series and that Spiker you've got looks beefy enough to take a pretty good amount of heat. Nice pics btw!
