    5mW laser near a airport

    You got to be careful using even weak laser nearby airports. On a different note but related to that topic: There are however exceptions when it comes to pointing lasers at aircraft: At least in my country judges rule in favor of shooting down drones when they are inside the " low altitude...

    Nichia nubm07e from Germany

    Well I got 2 NUBM07E delivered by now - one from a friend, one from a reseller (insaneware) coming with a partial copper Aixiz module. I was able to conduct a limited form of my originally intended experiment 2 weeks ago but only for about 1h, now with 2 465nm in my possession, I am ready and...

    Sanwu Pocket 488nm damaged lense

    Well, now it's too late either way as I deformed the top part of the lens when attempting to heat it up to remove the metal barrel from the old lens to no avail. Essentially, the top part is beyond repair. Well, I tried. I just have to order a whole new top part (likely some more for backup)...

    Sanwu Pocket 488nm damaged lense

    I am going to try removing the metal barrel by heating it with the soldering iron first, I had no luck by brute force. That is my option B, but it's unlikely that I manage to do it without damage to the lenses. Of course, there is light at the end of the tunnel, If the heat wont work, I am...

    Sanwu Pocket 488nm damaged lense

    Could you maybe show me an image of the pick you used. Just tried for half an hour, I wasn't able to unscrew it. Even if I get it out, I have to screw the other one in and there is no chance of not damaging it in the process, maybe option B is easier.

    Sanwu Pocket 488nm damaged lense

    Well I got the 3 element lens from Sanwu delivered (Lens at the top). I am not quite certain how to proceed though. The other two parts are from the Sanwu Pocket laser - I have to remove the remaining parts of the old lens but I can't get it out. Option B would be too remove the lens from the...

    Nichia nubm07e from Germany

    I am generally interested - right now I am waiting for my delivery of the NUBM07e from insaneware ( It's unlisted in their store, but they got that diode either way). I am planning to stockpile a few though, I will get back to you once I got my first delivery and do some tests, hopefully next...

    Sanwu Pocket 488nm damaged lense

    I reached out to Sanwu and they said that the G2 7mm may work but I would probably need the original 3 element lens, which I accordingly ordered. I keep this thread updated on the repair process.

    Nichia nubm07e from Germany

    I need(ed) that 465nm nubm07, the wavelength in that case is really important - still, that's an incredible generous offer, I appreciate it. Yes, I fear the same with the delivery time and I can't wait that long, in reference to Encap's post: to which I absolutely agree, I am going to...

    Nichia nubm07e from Germany

    I appreciate your offer - I am reaching out to multiple resellers and choose the fastest one. Sure it arrives quickly in the country with some DHL premium service - but commonly, I got to add up additional time for customs when ordering from anywhere outside EU - I had a laser from Honk Kong in...

    Nichia nubm07e from Germany

    There are some resellers in Germany for Diodes - but not for the NUBM07E. I did diode pressing, it is pretty annoying though - I would rather avoid it. I need that specific wavelength and a specific desired energy density which is best provided by that diode to quickly verify a mathematical...

    Nichia nubm07e from Germany

    Thanks, I know of DTR's shop though. Delivery time is even with premium shipping quite long unfortunately. That's why I asked for a reseller in Germany (my location). If there is none, I will buy from DTR and have to wait a while I suppose. I am sorry about the violation of LPF rules - I was not...

    Sanwu Pocket 488nm damaged lense

    Unfortunately, the lens of my Sanwu Pocket 488nm got damaged, the beam is unfocused and quite divergent now. Additionally, I possibly lost the spring inside - I am not certain if that one had a spring inside though - it's been a while since it got damaged and I can't quite recall. The diode...

    Hello laser enthusiasts

    Hello everyone I am a (soon) 27 years old computer scientist from southern Germany. I got fascinated of laser by watching videos thereof on youtube. I like the beauty and "pureness" of the laserlight, the fact that light can be bundled so strong that it is able to even cut metals. I already...

    Laser 304 lens cleaning

    The lens on the green one looks like glass to me, but it's hard to tell. I would rather test out the optical cleaning on cheap lasers than on more expensive ones, what kind of cleaning supply would you recommend for acrylic/ glass cleaning ? Someone claimed that lens pens from photography shops...

    Laser 304 lens cleaning

    I recently acquired the Laser 304 collection (https://www.sanwulasers.com/Green_Red_Violet_304_Laser_pointers/p3911805_15832422.aspx). I am satisfied with the product and I will order from Sanwu again soon. I do however wonder how to properly clean the Laser lens. I can see dust particles on the...

    Sanwu Lasers - Offical thread

    Good news everyone, the state of the delivery changed to "The item was posted and is currently being delivered". So it passed customs. I am so excited for my first lasers now :)

    Sanwu Lasers - Offical thread

    So the combo 303 lasers I ordered will be delivered in parts in order to avoid being seized by customs, if I understand correctly.

    Sanwu Lasers - Offical thread

    Thanks for getting back to me, after Immo1282's reply I am glad the batteries are delivered separately. From your experience, are problems when shipping handheld lasers to germany usual ? Right now it is still held by customs.
